My friends computer still has a black screen, for those of you who remember. For those of you who don't... My friend fried the video card in his computer, then he bought a new one. So, like an idiot he takes his CPU out of the socket and lays it down in the bottom of the computer case. To make a long story short: I bent the hairs on the CPU back & I FOUND a new video card & bought thermal compound. I put the video card in, put the CPU back in, put thermal compound on the CPU & put back on the HSF. Then turned on the computer & it went to a black screen. What is wrong? It won't even go to BIOS.
