So recently when playing a video game on my windows 10 pc my screen went black and the graphic card's fan speed instantly increased. After a few seconds my screen reappeared, my game stopped working and a popup message told me my graphics card has stopped working and sucessfully covered. I restarted my game to find out a few moments later that square pixels all over my screen appeared and shortly after my computer restarted. Going back into my video game the square pixels reappeared but quicker this time and my pc restarted. Upon start-up I went into my browser only and my screen went black, fans sped up. Then my screen reappeared and the pop up message stating my graphics card has recovered appeared. This happen immediately after multiple times till finally pixels appeared and my pc shut down. Sick and tired I left my pc. A few days later I tried to turn on my pc and random pixels appeared on start-up and are horizontal dashed lines now. My windows won't load and keeps restarting. A few different messages occurring are ; overclocking has failed, windows couldn't start up. I reset all bios setting and the overclocking has failed went away but windows wouldn't load up. I tried safe mode and that worked but that was it. It seems to me my graphics card is the issue as I changed it with an older one and windows successfully started up. I don't understand why this is happening and without using a new graphics card how I can fix my current one as I feel like it can still work but something is making it not work . I have a nvidia gtx 580 asus graphics card. 64bit windows 10. Asus rampage 2 motherboard .

The problems you are having sound like overheating. If you aren't ready or able to upgrade your current GPU, you could try taking the HSF off, clean out the heat sink, and reapply TIM. You might also need to apply new thermal pads to the VRM's and VRAM. Those types of issues seem to show up most with VRAM issues, and the lines seem to be mostly VRM issues. Since you have both, you likely need to replace those. The speeding up fan is likely the GPU itself overheating. Another possible issue is the PSU is failing, but that usually results in hard shutdowns, not recovery messages.

After doing research online myself I believe that you are right in the high temperature has cause damage to the video cards memory. Unfortunately it seems that this is something that cannot be repaired once destroyed. If anyone else if reading this I would suggest highly that if you are experiencing and overheating issues with your graphics card to deal with it a.s.a.p. Otherwise you'll end up in my situation with nothing to spare but a big bill. I think my graphics card was going down this route either way as I've been battling issues with it over the last year or so. Changed the fans, cleaned it out, tried everything to ensure it was running at optimal temperature but Im not entirely sure what I missed it could be what the user above said about thermal paste or it could be something else. The moral is don't avoid maintaining any computer parts wheather that means cleaning out your computer internally, changing thermal pastes, running diagonostics, and making sure yourself everything is running . I tried but neglected to look at all the maintainence requiredments.
