Dead PSU?

[Platinum]

Ok so I was just on the PC and it shut itself down, now when I try and power it on I get 2 quick beeps constantly repeated, the PSU doesnt sound healthy making a odd noise.
The PSU is a Enermax Infinity 650 Watt, tried a different kettle lead and that didnt help.
Any ideas?

check your mobo manual for bios beep/error codes. sounds something like ram / cpu are messed up... either way it'll give you a hint. doesn't mean the psu isn't messed up too though, but i wouldn't expect an enermax to kill anything else if it went up.

Its definatly the PSU beeping not the mobo.

Short the green cable on the 24pin plug with any black one (paper clip?) - does it power up and spin?

2 beeps = PSU protection active. (red light as well)

unplug it from the wall, leave it for few minues and plug it back in.

I would also run your PC without any HDDs, DVD roms etc and then add them until it trips again.
