Hello Guys,
I have got a problem:
I have just changed my bios options to OC (Overclock) mode. After 10 minutes I have just changed to normal mode (also restored default settings) and then restarted my PC. After logging in in Windows, 10 secounds later, I will get a blackscreen. My PC is still on, but I have got a blackscreen.

I have just read on some forums that the graphic driver is a problem. I have restarted my pc to save mode and there was no crash. Then I deinstalled the graphic driver. Still no crash. After installing again the driver, the crash appears again. I also tried to install an older versions. Can someone help me to fix this problem?
