View Full Version : Graphics Corruption Issues in Games

I have started having graphics corruption issues in 3d apps (games). 10-60sec into a game the computer locks up, and I see blocks of V-shaped patterns on the screen. The problem is repeatable and happens every time I launch a game. I have no problems at the desktop, internet, etc. Only games. Up until now my system has been perfectly stable. I have made no recent changes to the system cofiguration.

I have checked temps, and they do not seem to be the problem. The GPU never got over 78C at crash. Besides, I've seen it run a bit warmer after a couple hours of gaming before I started having the problem. My processor and chipset temps are all within spec as well: CPU - 37C, motherboard - 33C, and chipset - 45C (the nForce 4 chipset runs warm, but well witin spec). The heatsink on the card is clean and free of dust, as is the rest of my system.

I also checked my power supply with a voltmeter. The rails are all within spec: +12.10, +5.15, and +3.31 at time of crash. I never saw the voltages varry more than 0.1 volt. The PSU is designed to run two cards in SLI (it has two PCIe 6-pin connectors), but I'm only running one card so far. I tried switching PSU connectors to the vid card. I even tried using the 6-pin power adapter that came with the card instead of the 6-pin connector from the PSU (uses two 4-pin molex to provide power to the vid card).

My RAM is stable - I ran Memtest for over 24 hours with no errors. Ran SuperPI and Prime95 with no problems.

I had been running the 91.31 Nvidia graphics drivers for a month with no problems. I tried rolling back vid drivers to 84.25 but still have the problem.

Finally, I was able to borrow a PNY Quadro FX PCIe card and ran 3d apps all evening with no problems. I know it's not an apples-to-apples comparison, but it's the only PCIe card I could get my hands on.

Seems to me I have narrowed the problem down to the video card. Looking for other troubleshooting suggestions. Is it time to request an RMA for the card?

Thanks in advance.

Sounds like you covered everything. I would say there's an above-average chance it's your video card.
