Hey guys, my secondary computer has been getting blue screens when I try to do anything with graphics (such as gaming) or sometimes if I simply turn it on, so it's random. I'm not sure if it's overheating, or if maybe the HD is going bad... First, here's what triggered it... A long time ago I tried to add a new graphics card (8x) and the slot was 4x. Nvidia said that the new card would adjust in speed, so no worries. I did it, and it started having blue screens, so I uninstalled the drivers, and re-inserted the old card, along with its updated drivers. Ever since, it just restarts randomly. I can't pay games at all either. I don't know what the problem is here... It COULD be overheating, but I don't think the temperatures are bad, according to Everest. The temperatures on this old computer are actually better than my new one! I thought that maybe my HD is going bad? I don't know of any other parts witch exception to the card or HD that could have possibly gone bad. Please help if possible, as it's driving me crazy that I can't figure this out!
