My buddy's computer started acting up recently, where it started to freeze or restart his computer while he was doing intensive tasks(tabbing out of games to do some web searching, raiding in games, etc...). So after some searching online he replaced some parts in order being: HDD, Power Supply, Memory, and Videocard. After replacing all of these we gave up and went with a new motherboard as well. AM3 motherboard w/ matching processor(not sure what his model is at the moment). When he starts his computer now it says "CPU Fan Error" while his fan is working. So after bypassing it he now gets the blue screen of death. Any suggestions at this point? I told him to try reinstalling windows 7 but haven't heard any word yet(he's been at work now since). If this does not fix it, any suggestions of what to do? From what I understand if a CPU is dead then his computer wouldn't start up at all... it's getting frustrating since we're so close to Diablo 3 launch!
