My computer has the following problem: every time I start my pc, I get one of the following problems after a certain time period, sometimes a few seconds after loading my profile, sometimes after more than 20 minutes. The problem comes in 3 variations: 1) Frieze: the screen simply freezes; in other words, the site or the program that's open at the time; stay there, mouse and keyboard refuse to function. Nothing works anymore, such as website animations are frosen, and so on. 2) Spontanious reboot: the pc reboots by himself, without me asking it. One moment everything is Ok, the next the screen is showing the regular boot codes. 3) black screen: the screen simply goes black. The pc stays on, but keyboard and mouse don't respond anymore, not even caps lock leds. The pc appears to have entered sleep mode, but it won't do anything anymore, no matter what you do, or how long you let it stand up. Here follows the DirectX diag report. I'm a hardware noob. I checked for virusses and spyware, nothing. I also did fragmentation and such, (altough no system format) and it doesn't help a thing). EDIT: the problem occurs every time, and it occurs about 5 to 10 times before the system seems to be stabilised.
