Well for starters I would take the side of the case off, then power it on and look at the fan making the sound. Some times the bearings go bad, if this is the problem replace the fan. John
I built a home pc a while ago. recently, it won't start properly any more. by that, i mean, after i press the start button, i will hear the cpu fan running really abnormally loud.
then i have to shut down the computer. unplug the power cord to the computer case, and unplug one of the power supply to the mother board.
then i will wait for a minute or so, plug them in again, it will then start properly.
can anyone tell me why? and if it is ok to do it forever? will it damaage my pc, etc?
