I just purchased a new motherboard, processor, RAM, and power supply for my Desktop. I have been trying to boot the computer using my hard drive from my old setup which had Windows 7 on it. Whenever the computer boots it goes from the bios screen to the Windows Boot page with the logo but then it goes straight to a Blue Screen. When the Blue Screen comes up it only flashes for a tenth of a second and then restarts so I can not read it. The same thing happens when I try to boot the computer in safe mode.
Just looking over Tom's Hardware when I found this thread. I had the same problem. Did what you said. No more problem. Thank you all for answering these questions, even though I did not ask. Thank you again!
