We've had some wind/thunder storms recently which has had an effect on our house (Other computers shut down, aircon turned off etc) but my computer staed on through it all. About a day or so later, my computer decided to shut down and not turn back on again. I tried removing other components and swapping stuff out but no luck, so i tried switching PSU's and it worked flawlessly. My only gripe is the fact that the PSU i had in there (which is miles better than the no-brand one i have in it now for testing) is barely a few months old and i believe it's a high tier psu Antec TruePower Classic 650w. Whenever i try and boot my computer with it, nothing turns on at all (Only motherboard light). If i put my ear up to the power supply, it makes a faint BOOP sound and kind of like a hard drive reading sound. "BOOP *2sec pass* BOOP *2secpass* BOOP". Is it really, dead?
