My computer has been acting up lately but tonight has topped it. I was changing wallpapers on my desktop tonight and my desktop was locking up (not the first time it has done random lock ups but was fed up with it by now) so I though maybe its the graphics cards and went ahead and installed the newest drivers it was going smoothly until it started installing the new drivers both of my monitors went black (which always happens to me) but display did not come back at all. So I thought ok I will wait a few mins and it should come back, after about 5mins I hear this roaring fan noise coming form inside my computer which sounded like it was coming from my gtx 660 and gtx 550ti at this point nothing was responding. So I just went ahead and hard shut it down, I have not turned my desktop back on for fear of causing damage to anything. any help is greatly appreciated!
