And it crashes every 2 hours. Black screen appears. When rebooting a red highlight messege
says that my hard drive is not detected , "please select a proper boot device". After second reboot windows loading normaly. Temperatures are fine.
what you need to do is take another Hard drive and put it in the machine. at this level there are only a few things that can cause this kind of a problem. if the computer has the same problem with a different hard drive you know it is a problem with the motherboard. if that is the case then i would just RMA the board. if it fixes the problem then there is either a problem with your install of Windows 7 or your Hard drive has issues.
