I built a computer like four months ago, but now there seems to be a high pitch noise coming from what i believe to be the powersupply. The powersupply unit is the one that comes with the Antec sonata ii, The 450watt smartpower 2.0.
When the computer is turned on it has a quite annoying high pitch sound coming out of it. When i turn off the power, the pitch changes to a little lower pitch, but it is still there. When I either take the plug out of the wall or flip the switch on the powersupply on the back, the noise stops. So am i right to assume that the powersupply is causing my problem?
So, is there anyway to fix this problem and do you think the psu will blow soon? The sound is very annoying and if it cant be fixed i will probably replace the current unit. I just recently started college and I didnt notice any computer stores in the area so I will probably be getting the new PSU at bestbuy :\ .
I need enough power to run 7900gt, amd 64 3700+, 1 floppy, 1 harddrive, 1 cdrw/dvdrw drive and onboard sound. I assume i do not want to go under 400watts when looking for a new unit. If bestbuy has antec or forton supplies i'll probably get one of those, but if they dont, what other units should i look into getting that will be around 100 dollars?
