High Pitched Noise Problem

[TomElZ]

Alright lads, well another PC problem with me.

Last night my computer randomly decided too switch itself off. Once I had realized it had gone off I tried to switch it back on again. It wouldn't work but I heard a High Pitched noise coming from the PC possibly the PSU.

I think I pretty much confirmed this by switching the PSU switch off and the sound had gone but once I switch it back on again its back.

Doubt very much its anything to do with my mobo as I've recently just had to get a new one of them.

I did overclock my cpu about a week ago but only from 2.0Ghz to 2.50Ghz and the temperatures where fine. So I doubt that is the problem. My CPU is an AMD Athlon 64 3500+ and my power supply is a Hyper 500W PSU.

Any quick response would be greatly appreciated.

Funny thing is when I don't have music on, I can hear the "squealing" in my headphones. Talk about ear ache



My OCZ Psu has always done it, I've never had any problems with it. BTW I've had it for about 7 months.

Edit: Just read that your computer turned off, does it turn off randomly all the time or was it just the once ?

It was the first time it switched itself off mate. And I wouldn't know because it hasn't turned back on ever since lmao

Just ordered a new PSU so hopefully that will fix it!
