Power Supply Meltdown Help Needed

[Geezer_OMO]

Last Monday my computer power supply failed. I had shut it down the night before and the next morning it was dead. I took it to a local computer shop and they tested my power supply and they confirmed my fears.

Hence, I ordered a new PSU (both corsair) and sent my old one in under warranty. On Friday I installed the new PSU and it worked fine for one day and now it is dead as well!!!!!!!!! My computer was running fine and then it just quit. So, what could be causing this? Is this just bad luck with regards to PSU or is there something else frying my PSU? The surge protector is fine and my back up computer works fine with it. Any ideas what could be causing this???? I need help as I am at a loss......
