Hello,

My PC has worked fine for a year till today my CPU FAN (i5 750) stopped working but my pc still posted (i learned that it was not working because post said so) - so it scared the *** out of me and I turned off the pc.
The problem persisted for about 10 min (during which time I tried to turn it on a couple of times - unsuccessfully). Then, suddenly and unexpectedly the fan worked again, just as as if nothing had ever happened... I am scared!! lol nothing makes sense since i didnt touch anything...

System
-Motherboard P755D EVO
-CPU i5 750
-ATI HD 5850
-G. Skill 4 gb RAM
-HAF 932

Never overclocked anything- everything is stock, including the CPU Fan.

Please could you give your expert advise on what the problem may be? I heard this series of mobo p7p55d are prone to problems.. What do you think?

THank you so much for your ideas!!!

Maybe the fan is just dieing, the simplest solution would be to replace it.

No. The Bios controlls the fan according to heat, if the fan is off meaning the cpu is cool enough. It should turn on as soon as it gets a little hotter.

Lol.. maybe it depends on the power plan you have set? play with it a bit and check if it comes back,Snet could be right. You could try running a game or creating a rar archive and see what happens..if the fan goes off after a few secs of running the game, then it will be fine, you would have a power saver plan or something.

hmm... weird thing since it had never happened to me and fan is stock..
Anyways, You guys are probably right and I should not worry since computer is running just fine and is 100% stable so far :p 
thanks !!
