I have a 1 1/2 yr old HP Pavilion Elite M9340f Desktop computer. For a while now it's been crashing. It comes up to a blue screen with the F11, F10 setup, etc options. It stays there. Occasionally during this time I would also experience CPU Fan Failure error and it would immediately shut down. When I could finally get it back up, I finally just formatted the HD and reloaded windows. As soon as I did that, it didn't crash, and no CPU fan failure errors. (coincidence?) Anyway, That resolved things for a month. The next time this happened.. I reloaded windows, it resolved things for a week. NOW, all I get is CPU Fan failure error and it shuts down immediately. Let me just add, that ALL fans appear to be working properly. I even disconnected and reconnected plugins etc and also took a can of air and blew everything clean. I still get the CPU Fan failure error and it shuts down immediately. Also, I made sure the fan and heat sync were seated securely and properly. This is a store purchased computer from Best Buy, not home built (Which was probably my first mistake). I cannot get into the BIOS. It shuts down too fast and responds to none of the keyboard commands. Any ideas? or am I looking at a new MB? Thanks!
