while i still believe its possible heavy 24x7 torrent downloading could have been a factor, its more likely (like other posters said here) that you have a bad/unclean PSU/UPS/whatever that is causing electrical damage? my place in pune has the worst electricity supply i've ever seen, constant fluctuations spikes/dips so i have a corsair vx450 and APC UPS and hope thats enough. if i turn on a normal incandescent bulb you can see the damn thing flickering all the time with the bad power
even the UPS sometimes "clicks" on and off at a high rate even when there is no actual power cut, just due to the bad fluctuation
