lol - Actually it is the other way around, a faulty PSU can cause other problems with hardware componenets. It is the PSU that powers the components, not the components - what a load of rubbish.
If you get that on a regular basis you might want to check the power stability in your area - PSUs are rated to work between a given range (usually 90-135VAC) that is extreme, ideally it should be 110-125) a too low voltage at the AC is a PSU killer.
Now a GOOD quality PSU will feature special cutoff circuitry to protect itself, same for short circuit and overload......so if one of your hardware component has a short or whatever the PSU would shut off.
Did you buy a ready made system ? Most of the time cheap components are used, including a cheap generic PSU.
Don't pay that scammer his $59 - just get a DECENT PSU and install it yourself. The PSU is held by 4 screws, has a main connector to the motherboard (you can't go wrong) and the molex connectors for your drives (again can't go wrong, they are all keyed to fit properly) don't let anybody scam you and blame your PSU problems on your hardware.
