I was out of town for 2 weeks, and had left my computer on. I know there were a few storms during my time away. I came home to find it off, and when I hit power, it won't power on at all. The computer was hooked up to a UPS Cyberpro. My Powersupply is maybe a year or year and a half old, its a Thermaltake Black Widow W0319RU 850W ATX 12V v2.3, EPS 12V v2.91 . I've tried a different power cord from the wall to the PSU, but nothing. Any ideas? Should I try clearing the bios? Take it in somewhere? Buy a new PSU? I'm baffeled.
