|I have a Dell Optiplex running Windows XP. Used as a home computer. It is usually left on 24/7. It hung up the other morning and when I shut off and tried to restart, no boot, just the fan slowly, over the course of 30 seconds, revving to a previously unheard of pitch. At that point, I shut it off and headed to work. Some forums dealt with something similar and said that letting it sit for several hours may fix it, that it could be heat related. Got home that night and no dice, same thing. The inside is fairly clean and this pc has not had any issues since I purchased online at Ebay 2 years ago. There is a yellow LED on the motherboard that stays lit, if that helps.|
Not a very technical person, any help would be appreciated.
