    The fan on the Power Supply keeps going on and off. It spins for about 1 second then turns off then turns on. Sometimes the fan spins for more than 1 second and it makes a weird squeaky noise. I haven't cleaned my PC properly in months... I used a hair dryer to blow away the dust but problem is still occurring. Should I open up the PSU and clean it further... or is it time for a new PSU?

    A ahir dryer probably would not provide the appropriate air pressure to do a good job, I suggest trying to clean it with a can of compressed air. These can be picked up for about $3 at walmart, kMart, just about any store that sells electronics. Alswo a cleaning about every two weeks would be a better scheme. I take 5 computers out to my work shop at least every two weeks for a good dust removal. But then I have a small compressor with an air nozzle and turn the pressure down to about 20 PSI.

    How about giving us your hardware and/or pc make and model. If this psu has more than 1 fan, it could be it is meant to go on and off with needs, but you have told us absolutely nothing about the psu or the computer so it is really impossible to help you.

    My PSU has 2 fans... but both are meant to work at the same time because I had this computer for a couple years and that is how it has always ran. My PSU is Cooler Master 1000 watts.
