I am working on a friend's computer and am a little stumped. I get the CPU Fan Alert, previous fan failure when it boots. I hit F1 to go past that because the cpu fan appears to be running completely normal. It boots, and then when you click on a profile to log in, it immediately goes to blue screen and shuts down. I can't even get the blue screen error code before it shuts down, but assume it is tied to the cpu fan alert on boot. The computer is not getting hot...it doesn't even have time to get hot before it shuts down, and it happens when you try to login every time. Can't even get into Windows to look at drivers etc. Any suggestions?
