Ok, so I recently upgraded to Windows 7, about a week ago. Since then I have been getting BSOD's when I am not using my computer, generally when it goes to sleep for a while. I work 12 hour days and every time I come home the computer is either off or has the "Windows recoverd from a BSOD" message. ALSO, my computer will run it's CPU at 90-100% constantly after I open Firefox and iTunes, this will continue untill I restart, then it will go back to 2%. I am using an AMD Phenom quad core processor with the 64 bit retail version of Windows 7 with 6 gigs of ram. I was using Vista 64 bit before I upgraded. Is there a way to fix this or should I just try reverting back to Vista?
