Question about Gigabyte GV-NX76G512P-RH NVIDIA GeForce 7600 GS 512MB Graphic Card
AMD Athlon64 3500+
MSI K9NU Neo motherboard
1.5GB DDR2 667 RAM
NVIDIA drivers, version 177.39
Windows XP SP3
I have had the Geforce 7600 GS card for more than two years, during which it worked fine. Recently however, while playing UT2004 columns of discoloured pixels appeared on the screen. Upon restart these pixels still appeared, although in different places with each screen to be loaded. The appear from the moment the POST screen of the startup appears. The Windows logo appears (also with pixel columns everywhere), and the system shows a blue screen of death and sets the screen to power saving mode.
The display is also garbled when booting into linux (Ubuntu and SUSE). Only in safe mode is the display not garbled (but it is still garbled during the initial startup phases).
My motherboard and graphics card updated with the latest BIOS. Various NVIDIA drivers have been tried, but none of these fix the problem.
The problem is definitely isolated to the graphics card: Another graphics card in my PC works fine, and putting the 7600 GS in another PC (completely different configuration) gives the same problem.
The problem was thought to be overheating, since the temperature was high at times. This was fixed with an extra fan attached to the graphics card. The problem was fixed when running undemanding tasks, but as soon as a more demanding task (game / benchmark) is required the problem returns. As soon as this happened the again displayed the problem from the boot screen.s t
During many restarts the PC worked only twice, but under load the problem returned. It is as if putting the card under load triggers the problem. Temperature could not be a problem: cooling the card to very low temperatures outside the box and then inserting it also resulted in a garbled display during boot up.
It seems that the fault lies with the graphics card, and that this fault is not due to overheating and not due to software (not BIOS nor drivers or operating system).
Please advise on where the fault lies (and if possible, how to fix it). Thanks.
From experince I would still say this is a heat issue, I just went though this with my HD4870 ATI card. I was using an after market cooler wich was insuficent for cooling. All the symptoms point to a heat issue. Also since the card is 2 years old, its a good chance the VRM's have fried and any heat causes the card to basicaly shutdown in a manner of speaking. you could try getting the Accelero S1 cooler that would replace the fan on the card, then attach 2X120mm fans. Only problem is you can buy a newer better card. for example the 8600 GT is about 80-90$
