1 gig of corsair pro memory
250 gig sata drive
winfast 7800gt pci express graphics
when i play cod 2 on computer after about an hour the colours change from green to blue red etc
then it freezes up and crashes
it plays cod and cod uo with full settings and no problems
please help as im going mad with this problem
also i installed a adsl modem usb
and it keeps losing its drivers so i reboot then it comes up with insert boot disk

if i swap the sata drive from sata master port 1 to sata master port 2 it will fire up without a problem
and i can then put the sata disk back into master 1 port
thanks for your help

Reduce the cod 2 settings. If that works, then the video card may be overheating. Make sure its fan is running at the correct speed, and its heatsink is securely mounted.
If those are ok, then remove the computer's cover, and run an external fan blowing on the video card. If that works, then your system needs either more powerful or additional case fans.

WRT the SATA problem, the SATA 1 port may be bad.

thanks for the advise ski
i run 2x 120 fans as well and 1 side fan inside a raidmax ninja 500watt case

You're welcome.
What are the temperatures and voltage readings in BIOS?

[alanpryor]

temp for processor is 28 degrees celcius
temp for memory is 35
fan is working spot on on graphics card

Have you tried the lower setting yet ?

[saphalline]

Drivers. Check all the drivers. And DirectX. Make sure all of that is up-to-date. Could also be a BIOS problem, but try the drivers first.

i have lowered settings and problem persists jiggy m8
i will download new drivers and install also having problem with prince of persia as well
thanks for your help guys much appreciated

[alanpryor]

What are the BIOS voltage readings?
Also, remove the computer's cover and run an external fan on the video card.

i put a new pci express card into the machine and the problem went away
verdict faulty card

Glad you fixed the problem. Now you game without interruptions. :D

I had almost the same problem, 'cept once the level loaded, the comp crashed. I believe it was the graphics card sucking too much juice from the puny PSU in my old eMachines. The voltages at IDLE were nothing short of pathetic
