Display is not working on the monitor. How to fix it?

Display is not working

There are times when you turn on the system and you find out that the display is not working, not only screen but also the mind goes blank! Not anymore, This post has tips you can follow to figure out the problem and think of solution.

If the problem is not blank screen but a blue screen with errors, refer to the post about blue screen of death and how to troubleshoot it.

 

display is not working

Monitor is off

Well, make sure the monitor is turned on. Check the LED. If no light comes on after several attempts, proceed to the next section.

Computer in sleep mode

If you went away from the computer for sometime and returned to a black screen, it is likely that the computer is asleep. Move the mouse, press buttons or any key. If none of those actions work, press the power button.

Loose connections

Check the data cable

Make sure that your monitor’s data transfer cable is properly connected to the computer. It should be firmly in place. Most new displays uses a DVI or HDMI cable and port.

Check the power cable

Ensure the monitor is getting power by verifying that is a light (blue, green, or orange) on the front or bottom of the monitor’s panel.

When you see no lights on the monitor, make sure it is connected to a working wall outlet. If the power cord is removable from the back of the monitor, replace it with another power cable. If you still cannot turn on the monitor after trying another wall outlet and cable, the monitor is broken and should be replaced.

Check  LED status

If the monitor status light (mostly located on the bottom of the monitor’s bezel) is orange or flashing, the monitor might be in a suspend mode, to come out of it move the mouse or press a key on the keyboard. If this does not help, reconnect the data cable to the computer and back of the monitor, and then restart your computer.

Try with different cable

If your monitor is getting power, but you don’t see an image, the data cable may be the issue. Try another DVI, HDMI, or VGA cable with your monitor.

Turn up the brightness and contrast

When you’re able to view your monitor’s settings menu even though the screen is blank, maybe  you need to increase the brightness and contrast.

Failed POST

If the computer doesn’t pass Power On Self Test, it won’t turn on and your monitor will remain black. If you hear beep sounds when you turn on your computer, run through the POST troubleshooting steps to find out the problem.

Hardware Problem

If you have followed the tips above and still have the same issue, your computer may have either a improper monitor, video card, or motherboard. The best method of determining this is to try the suggestions below.

Get someone else’s computer a computer monitor and connect it to your computer

If another monitor works on your computer, it means your monitor is bad and that might be the reason display is not working. While it may be possible to have the monitor serviced, it is often cheaper and easier to purchase a new one.

Connect your monitor to the other computer

If your monitor works on the other computer, the chances are that your video card is bad. Remove video card from the affected computer and install it in another computer. If it does not work in the other computer, the video card is probably not working and needs to be replaced.

If your monitor and video card works with another computer, your motherboard probably has an issue. You can attempt to troubleshoot motherboard problems. If you find out the motherboard is bad, or you are unable to successfully run diagnostic tests, motherboard replacement might be needed.

Tips for buying laptop

buying laptop

Things to check out while buying laptop

When purchasing a computer, it is likely that you are going to have a general idea of what you may like in the computer or how you would like to configure the computer. Below is a listing of the various components likely to be found in a computer, and recommendations and tips for components

Battery usage

Determine how long the battery is expected to last under normal use. Many manufacturers will indicate a battery usage time but this may be at the lowest possible settings; ensure that the manufacturer clarifies what the standard battery usage life is when using the portable computer in all power modes.

Display

All portable computers come with a display. While it is almost always possible to hook up an external monitor when traveling with the laptop, the display is an important consideration. When looking at the display, ensure it is large enough for your needs. If you want to reduce the cost , go for smaller screens, unless price is an important consideration we highly suggest that you purchase a laptop with at least a 12″ or larger LCD and recommend an LCD size of 14″.

Drives

Drives are can be an important consideration, overlooked sometimes though. Portable computers can come with various drive configurations, for example:

  • One drive bay where the CD-ROM and the Floppy drive are interchangeable. For users who utilize the floppy drive often, this may be an issue; however, for other users who do not utilize the floppy, this actually makes the computer lighter and thinner with one drive bay.
  • Two drive bay portable computers have a floppy solution as well as CD-ROM solutions. These computers will be a less expensive computer when compared to the other solutions; however, it adds on the weight to computer.
  • No drive bay portable computers allow for a laptop to be extremely light and utilize external drives instead of internal.  while it may appear to be a portable solution, many manufacturers will charge you an additional price for the external drives, which will eventually be needed.
Hard drive

Hard drives have and always will be an important consideration to think about when purchasing a new portable computer. Like a standard computer, the hard drive will be the destination of all your files and information, and if that drive is to become full, that drive must be replaced or another external drive needs to be added to the computer. When looking at the space of the hard drive, always get the maximum size hard drive, considering you will always have plenty of files to store.

Lock

Does the portable computer include any locking system? If yes, what locking system is included? This can be important for users who are on the move .

Memory

Memory is and has always been an important consideration when buying laptop. Determine the amount of memory included in the computer as well as verify if that memory can be upgraded in the future. The more memory the computer has, the more efficient the computer is.

Modem

If you need a modem, ensure that a modem is included with the portable computer. In addition, verify if the modem is an internal or PC-CARD (PCMCIA) modem as you may require all the available PC-CARD slots in the future. PC-CARD modems are type II.

Network Card

Ensure that a network card is included with the portable computer. In addition, verify if the network card is an internal or PC-CARD (PCMCIA) network card as you may need the available PC-CARD slots in the future. Network PC-CARDs are type II that for most computers allows for an additional type II to be connected.

Processor

The computer processor is and will always be an important consideration when purchasing a computer. Today, with multiple CPU/Processor manufacturers, it may be more confusing as well as more cost efficient to look at the different processors available. Compare the different processors in line with your requirements and go for the best one while buying laptop.

Sound card

Sound cards are important, however, the majority of all computer users will find that most standard sound cards will suit their needs. However, some users may enjoy purchasing more advanced sounds cards that will increase the amount of speakers that can be used and in some games and programs and the sound quality.

When looking at the sound aspect of a portable computer, many laptops do not have sufficient sound and will require external speakers or headphones. Ensure that the sound quality meets your needs.

Weight

Weight is another important consideration when buying laptop as the computer will be carried; the lighter the portable computer, the more easy it will be to carry.

Video card

Video cards are becoming an extremely important factor when buying laptop. While this may surprise some, a video card can make or break a computer when it comes to playing games. Most games today require additional video memory as well as special video modes. With a video card with little video memory or without these modes, the computer will be unable to play these games. In addition, the advances in video cards can dramatically increase the user enjoyment of the game being played.

Brand

When looking at purchasing any brand of portable computer you will hear good and bad feedback. Regardless if the feedback is good or bad, these stories are always based on the experience of that user. While it may be true that the user had a bad or terrible experience with that computer, all computer manufacturers have had users who have had a bad experience and there is no such thing as a bad or perfect computer manufacturer.

Add-ons

Free add-ons? Some computer companies may entice you into purchasing a computer by giving you free add-ons. These add-ons may be advertised as free, however, ensure or ask if the add-on price is not just being added to the overall computer price.

Unless you have done your research on the additional add-on, do not consider the add-on. While in some cases it may be beneficial to get a printer, scanner, camera or PC Cards with a computer, you may be paying premium for the additional add-on, or in the case of the printer, you may have to pay premium on the ink in the future. Do you research, ensure that if you get an additional hardware or add-ons that the hardware will suit your needs and that it does not end up being something that is not going to be used.

Documentation

While most manufacturers today are reducing the documentation included with their computers, it is still a good idea to find out what documentation if any is included with the computer.

All computer manufacturers will include some paper documentation; however, does this information include documentation about upgrading the computer in the future? How to connect the cables to the computer? Documentation on how to use the software such as the additional included software?

Note: It is important to distinguish between paper documentation and on-line documentation. On-line documentation, which is being found more today, is information that is either locally on the computer or can be accessed via the Internet. If the information is available over the Internet, see how that information looks and if it suits your needs before purchasing the computer.

Location

We use location to describe different cases. First, what is the location of where the computer is purchased: If the computer is purchased at a local retail store, can the computer be returned to that store if unsatisfactory? If the computer is purchased through mail order or directly through the computer manufacturer or reseller, where can the computer be returned if unsatisfactory?

Second, can the shop location of where the computer was purchased service the computer? If not where is the closest location to where the computer can be serviced?

Third, if the computer is purchased directly from the computer manufacturer and is shipped through mail, how is it shipped? What is the time period for the computer to arrive to your destination? What happens if the computer is damaged during shipping?

Refurbished

Refurbished is a term used to describe a computer or a hardware device or component in a computer that has been used; however, it has been looked at and determined to be in working order. However, because the product has been used or purchased, it cannot be sold as new.

Refurbished computers have a lower price and are a good deal for users looking for a better deal. However, compare the price of the refurbished computer to a new computer and the number of years it has been used.

Service

Service is an important consideration to look at when you are buying laptop, new or used. The service is how many companies describe the repair of a computer if it or a component within it is to become broken. Below is a listing of recommended services.

  1. Is the service onsite, meaning a technician will come to your location to replace or fix a bad component. If the service is onsite, is it for the complete time of the warranty?
  2. If onsite is not offered, what is and for how long?
  3. Can the computer be taken to a local service center? If yes, what is the closest authorized service center?
  4. What is the time frame the service takes to occur? For example, if the computer has a bad component, what is the time it takes for a technician to come onsite and replace that component, or what is the time it takes to have the computer sent in to be fixed? Finally, if that time frame is not accomplished, what is the company willing to do? Would they be willing to provide you with a loaned computer?
  5. Because the computer is a portable computer, is International Service available? This allows users who may be in a different country to have their computer fixed in that country.
Software

Software, for many computer users especially new users, is thought to be an important consideration when buying laptop. Granted there is software that we highly recommend looking for when purchasing a computer, such as word processor or spread sheet program, some computer companies may over hype the software package. Below is a listing of what to look for when looking at the software included with the laptop.

  1. Does the software include Microsoft Office or Corel Suite? These packages allow you to have a word processor and a spread sheet. For the majority of all users, this should be an important consideration.
  2. Is the software full versions of the software or is the software demo programs or shareware programs?
Support

Things to consider when looking at the support options of a computer are mentioned below.

  1. Is support open 24 hours, 7 days a week? If not, what are the hours?
  2. Is support open on holidays? If not, what days are it closed?
  3. What support options are available? Phone? E-mail? Web? Chat?
Upgrade

While this option may not be considered at first when purchasing a laptop computer, it is an important consideration. Below is a listing of different options to look for when looking to upgrade a portable computer.

  1. What can be upgraded in the computer? RAM? CPU? Hard Drive? If available to upgrade, what are the maximum amounts or is it specified within documentation provided with the computer?
  2. Whether the upgrades are something that the end-user can do or does it require a service center to install?
Warranty

Finally, what warranty is offered by the computer manufacturer? How long is the warranty? Does the warranty cover both hardware and software issues?

Warranty can cause frustrations for most users. A warranty of at least 1 year is highly recommended. Many cheap computers only come with a 90 day warranty; meaning if a part goes bad, you pay for the part as well as the service. This may not be an issue for users who just need a cheap computer and are willing to replace parts and service the computer.

 

Scams

Be careful for the below scams and tricks when buying a laptop computer.

Get what you pay for

Make sure you are paying for what you get. It has been known that computer companies may list a processor being a specific speed but may actually have a different speed into the computer. This, unfortunately, can be very easy as any user can ‘over clock’ a processor, making it appear as one speed but in reality being a completely different speed. For example, you may buy a 733MHz processor but instead get a 500MHz.

To determine the processor speed, open the computer and look at the processor itself( this might be difficult though). Do not look at the processor through a software program or through BIOS as these values can be changed or tricked.

 

Legal software

When purchasing a computer, ensure it comes with legal software. Many end-users or small computer companies who build or sell computers may provide you illegal copies of software. Verify that the software that came with your computer is on a standard CD and not a burnt CD. A burnt or home-made CD will be a different looking CD and have a gold or green bottom. Make sure that if the software requires a license or registration number that it was included with the computer. An example of software that includes these certificates is Microsoft Office and Windows.

Blue screen errors in windows and how to fix it.

There are multiple types of blue screen or blue screen of death errors in a Microsoft windows based OS. Before fixing it, it is neccessary that you should know the types.

If you get only blue screen without the error codes, probably the problem is with video card or the monitor. Check your video card and monitor in this case.

If you are getting a blue screen and then your computer suddenly reboots without being able to read the text in the blue screen, follow the steps below. when you are unable to get into Windows to perform the steps below, boot the computer into Safe Mode.

If you are unable to boot into Safe Mode, you may have corrupt Windows system files, a defective memory chip or a damaged hard drive. You should run hardware diagnostic tests to determine if the memory or hard drive is causing the blue screen errors.

**right-click on My Computer or Computer, from the start menu or desktop.
**Click the Properties option.
**In the System Properties window, click the Advanced tab.
**On the Advanced tab, go to Startup and Recovery section and click the Settings button.
**In the Startup and Recovery window, uncheck the Automatically restart check box.
**Click OK.

Blue screen errors

Windows NT, 2000, XP, Vista, and later versions of Windows have a blue screen error that is similar to the example shown below. These error messages often contain more detailed information and will contain information that you can search and find. If you’re not getting a blue screen error that looks like the example below, refer the fatal exception error troubleshooting.

 

blue screen error

Locate the line containing all “capital letters with underscores” instead of spaces, such as the above example, BAD_POOL_HEADER. Write this information down. If you do not see anything written in all caps with underscores like this, skip this step.
Get either the STOP: error message at the top of the error, or in the “Technical Information:” portion of the error. For example, in the above error, it is STOP: 0x00000019, write the first portion of this error message down.
Finally, if technical information is shown, write down the file and the address.

Once you have the above information, you can start troubleshooting the issue.

slow running computer? fix it by following these simple steps!

Are you wasting time waiting for an application to respond? Probably you might grab some coffee while it loads, or you can try figuring out the reason for slow running computer.

slow running computer

A lot of things in life goes slow, we can live with it. But a slow running computer isn’t so much of a fun.

The steps mentioned below will give an outlook on what can be done when a snail speed computer gives you a hard time.

1. Reboot

Rebooting the computer which is running since a long time might help. Sometimes the PC can be a mystery box and a simple reboot can fix the issue.

2. Temp files

The computer creates the temporary files while running programs. Deleting temporary files can free up space on hard disk and speed it up.

There are several utilities for it. Disk Cleanup is one such tool to delete temp files and other files no longer needed.

Alternatively, we can use the command %temp% from the “Run” option. once inside delete all the temp files.

3. Background programs

Disable or remove the “startup programs” which automatically starts when system boots.

To check out the program running in background and how much of cpu they are using, open “Task manager”.

Any Antivirus or security utility scanning the system in the background can slow down the computer.

4. Less Hard drive space

Make sure there is atleast 200-500 MB of free hard drive space.

“Swap files” can improve performance

5. Damaged or fragmented hard drive

Use “chkdsk” command or other utility to check hard drive physical corruption level.

Run “Defrag” to arrange data in best order on disk.

Get information about drive errors by reading “SMART” info using tools.

6. Check for malware

Malware and spywares can be the cause of multiple problems in computer. A regular malware scan on slow running computer saves the computer system from unexpected problems. Beware of the suspicious and fishy links when you browse through the internet. This link will provide you an insight on different types of malware.

7. Virus scan

viruses can make your computer really slow. Install a good “antivirus” to keep the viruses in check. You can use some free online antiviruses too if you don’t have one installed for active protection.

8. Windows Update

Keep your windows updated by installing updates regularly.

Update the browser plugins.

9. RAM upgrades

To run programs smoothly we need sufficient RAM. Increase the size of RAM on older computers.

To know how much RAM is installed, check “system properties” or use the command “msinfo32”.

Also run the program “windows memory diagnostic” to check the damage to the RAM at any point.

10. Overheating Processor

Use proper cooling solution(fan or liquid cooling) to ensure the processor doesn’t heats up soon during high activity.

Make sure the “Heat sink paste” or “Thermal Compound” has not dried up completely on the processor surface.

11. Reinstall everything

After trying the above solutions, if you still have slow running computer, Format disk and reinstall OS. Well, don’t forget to backup important data before formatting your disk.

12. Hardware Problem

Finally the failing hardware can be the reason of computer running slow. A bad Hard drive, RAM, CPU, or Motherboard can be the reason for slow or freezing computer system.

Further, you can run tools like, “ultimate DLCD” or ” Hiren’s Boot disk” to diagnose the problem.

Mostly the steps mentioned will provide a solution. If not, then definitely you got to contact helpdesk.
