Went blue screen. took it to Comp Usa and was determined motherboard cause VIDEO CARD bad? I am not so sure

yes it can be fixed

I would suggest adding it to the computer possibly as a secondary card if possible. Once the card (if it works) is installed run a benchmark or a game and see if the ps blue screens if not you can be pretty sure the card is ok. If the card does not boot at all and nothing shows up on screen it is bad

Hope this helps

Hook a spare monitor to the video output usually on the back, if picture is okay! the problem lies in the inverter board, "just below the screen" or the backlight behind the LCD display, or the video cable from the screen to the motherboard has come loose from the plugin. But if both show the same symptom it means the Video Graphics Card is defective, normally built into the motherboard.

Could be your video card(GPU) or bad pixels in the monitor itself.The best way to tell for sure is to borrow a monitor and hook it up to your machine.If the line is on the other monitor the GPU is bad,if not your monitor is bad.

It sounds like the on-board audio is dying, you could replace the motherboard but it is not necessary. You can pick up an internal sound card for around $20-$30, here is an example of the kind you would want.

Because they are so cheap and easy to install, i would say this is the solution that will save you the most time and frustration if you're willing to spend a little cash.

hello,

is your video card is on-board on the motherboard? if so, put external video card compatible with your motherboard and power it on.

your on-board video card is faulty you need external video card!!

hi this does sound like your graphics card has a conflict with another device, your best bet would be to go to the site of your graphics card manufacturer and download the latest drivers for your card, un-install ( actually delete ) the graphics card from the system, ie...add and remove programs, look for drivers for your graphics card, then remove, also go to your device manager and delete it from the hardware so there is no trace of it ( don't worry it will still work it will just default to minimal settings on re-boot) re-boot the system, if it says found new hardware and tries to install your card click no you don't want to install it, then find where you downloaded the drivers and install them and then that should stop the blue screens, games..this also could be the sound card has a conflict with something, as i know allot of games just crash to the desktop for this reason, try doing the same for the sound card, download, remove and install, as above...any more probs just reply and i will see what else there is, if you can also post the blue screen error on here to will be helpful as you can determine what the cause is...hope this helps

Try redownloading the drivers for your Nvidia Graphics card, but make sure you download the proper ones. It could be the video card, but it could also be a number of other problems. Usually the blue screen will say near the top of it what the blue screen was caused by though.

The BIOS is unable to access the video system in order to write any error messages to the screen.

This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.

If its onboard VGA (Video Card chip built on the motherboad, which I believe it is with a Compaq computer), it is possible the video chip went bad or might be a RAM problem. You can try to open up the case (unplugged of course) and take the RAM out and put it back in, or if you have more than one RAM chip try each one separately.

If you had another computer that uses the same type of RAM, you could try the RAM chips in another computer to make sure it is not the RAM that is causing the beep code.

But 1 long and 2 short beeps usually points to the video card/chip or the motherboard failure.

Boot into safe mode by pressing F8 about 10 times during the post screen. Then completely remove your video drivers. Then reboot, into windows normally, go to the Nvidia web site and download the latest graphics drivers for the video card that you have. If this does not solve your problem, then you may have bad video memory on your video card.
