Yesterday my processor fan starting running non stop after a couple weeks of it running fast occasionally. I took things apart to clean it to check if that was the problem. When I hooked everything back up and powered it on I got a beep code. It consisted of 2 second long beeps that just kept going until I disconnected power. I made sure everything was tight, reseated the RAM, tried again. The PC powered and booted no problem. I got a pop up telling me that my system had recovered from a serious system error. I ran a disc check, that was fine. Now after a few minutes of running the processor fan is right back to running constantly. When I try to shut down it acts like it's going to, I get the "Windows is now shutting down screen" and then it just stays there. I have to physically shut it down every time.
