Computer problem(s), video card, operating system or hard drive?

After using Google Earth 5 for a few minutes, the screen crashed and I pressed the restart button, however werid red lines and green square began to appear on the screen, is this a video card, operating system or hard drive problem? The monitor works perfectly because tested on another computer. Red lines and green boxes appear on boot up (BIOS, not OS), so what is the problem?



system specs:

1. AMD Phenom 9500 (2.2 gHz)

2. 6GB of DDR 2 RAM @ 667 mHz

3. 1X Western digestal 250GB SATA II hard drive

1X Hitiashi 1TB SATA II hard drive

4. nVidia Geforce 8400 512mb PCI-E 2.0x 16

5. Realtek 7.1 intergrated sound

6. AMD 790x chipset from MSI

7. a DVD reader and a DVD writter (both IDE)|||Quote from philip

Most prbabale cause is operateing sys.





Ask your self this, if the lines comes up during bios and not OS, how the hell would it be the OS when it hasn't even loaded the video drivers?



You have video corruption sir. http://freestone-group.com/video-card-st…

This is a link to a video card stress test. Video corruption is an automatic diagnostic, but just to be sure, download this and run it.|||Most prbabale cause is operateing sys.



how to fix reinstall the operateing sys.

It should run okay on the integrated video. You might have to get into bios to change the video setup, sometimes it is automatic, sometimes not.|||Well, it obviously can't be an OS problem if it appears before the OS is loaded. Likewise, it can't be a hard drive problem if it happens before the hard drives are initialized at boot time.



If you've ruled out the monitor as the source of the problem (which I wouldn't do until I'd tried the same computer with a different monitor) then the video card is very likely the problem. Try using a different video card temporarily to check for sure; if you don't have another card, see if your motherboard has a built-in video card.|||1. Shut off system

2. Disconnect power cord from back of puter.

3. Hold power button down for 10 seconds. (purges any residual power)

4. Open computer case.

5. Remove video card.

6. make sure fan moves easily and no excessive crud (if it has a fan)

7. After cleaning replace card firmly.

8. power back up.



It may be either card wiggled loose or excessive crud as both can cause this problem.

Or worse case scenario is that the video card died, easy enough to fix...

Definitely a video card issue.|||Sounds like a video card or video driver problem. Make sure the system is not getting too hot inside when under load.

download latest nvidia drivers and install over the ones you have. Make sure your memory is not running too fast in the BIOS. ie 800Mhz. BTW what were you thinking buying DDR2 667 Mhz Memory with a Phenom you should have at least got pc6400.
