Problem with computer shutting off on its own

730 Views 5 Replies 3 Participants Last post by  johnpost
ok, so my computer is shutting off on its own... at first i thought to clean the fans and the heat sink.. so i did that.. afterwards i hear this high pitched sound that seems to either be comeing from the processor or power supply, since they are so close to eachother... it still shuts off when it try to run windows normaly, right now im in safe mode with networking...i ran the set up to check to see if the processor temp was ok, its runing at about 185 degrees farenheit, i did see that the 3.3v was hitting 3.65 or so and was making the bracet go red...

its a pentium 4 with windows xp..

does anyone have any suggestions?

well so far ive done everything but the house fan part, ill re-check the the heatsink to make sure they are connected correctly, i also had a nother question, i noticed theres a silicon like substance between the processor and heat sink, now do i need to replace that when i put the heat sink back on or is it fine as it is?
