I've got an older Dell I'm trying to get back into working order. I mainly use it to run a few older games and that's really it. I'm more of a console gamer. 


The fan on my video card went out and it was idling at around 90 degrees Celsius. If I opened a program or tried to run anything my screen would start flickering with all kinds of random colors and then either stay that way or freeze up. Since I didn't want to do any long-term damage I bought an aftermarket heatsink to replace the dead fan. It works great and the idle temperature is now 40 degrees Celsius. However, the problem persists. The computer boots up fine and I can start Windows. If it just sits on the desktop it acts fine but if I try to open anything within a few seconds or minutes the screen will start flickering. I tried uninstalling the card and removing its drivers to see if reinstalling everything would help. It didn't. Usually it just locks up but earlier after flickering it threw a BSOD with a "NMI: Parity Check/ Memory Parity Error" message.


I'm not sure if the card is toast or if I have some kind of driver issue going on. Is there anything I should try?

Sorry to double post but I've solved the problem. I removed sticks of RAM until the problem stopped. The culprit appears to have been a faulty 512mb ram stick.
