1.	Solve : Powersupply makes high pitch noise?
Answer» Hey, i am helping my friend build a computer, and we seem to be having a PROBLEM. When we put the power cable into the power supply, and turn the switch to ON, it makes a really high pitch noise. This is really bugging the heck out of me because we are so close to getting this job done. Specs: AMD +2800 ASPIRE ATX Mid Tower Computer Case 420W Power Supply XFX Geforce 7800GT 1gb corsair ram 320gb HD CD-RW/DVD-RW drive i really hope IM not the only one with this problem, and i hope its something easy to fix, thanks, zell990 Some el cheapo power supplies display this as well as other problems. These can include no NAME ones that COME with an inexpensive case.so im guess what u are saying is that the Power supply is just crap?Who is the manufacturer? Do you have another to slip in there for a TEST? Is that a new case and PSU? If so, I would contact whoever you got it from.
