I have a MSI NX6800GT, which I bought along with the rest of my computer around August 2005. I wake up yesterday in my apartment and notice that the power had gone off, not sure for how long. I turn my computer back on it sounds weird. Sounds sort of like: vrrrr vrrrr VRRRRRRR vrrrr, over and over. Everything seemed to be running fine and I leave it on. Later on in the day it crashes, all these weird little boxes cover the entire screen and I have to turn the computer off. This is artifacting correct? This has never happened before. So I open up my computer and take the video card out. Well there is a huge layer of dust seperating the heatsink and the fan. I'm thinking maybe that's where the noise was coming from (but why now)?
I give that a thorough cleaning and put it back in. I turn on the computer and check and make sure all the fans are running. They are and the crazy noise is gone. Not even 20min later the computer crashes again. So I've left it off for 10 some hours and just turned it on now. I'm just waiting for it to crash again...
Would the power cutting off screw up my video card? If so, what are my options?
EDIT: Also, I don't think swapping it out and putting another one in is an option. The only people I know have notebooks or old Dell/Emachines.
