if you hadn't mentioned power outage, i would first suggest checking the power supply input type switch to make sure it is set to 110 not 220

Last post sounds good to me, just let me add. BUY A DECENT UPS !! Those weenie little power bars are useless when it comes to power spikes.
A good UPS can run you some $$ but will save your PC in the event of a hard spike. I've seen power spikesliterally MELT the so called "surge protector", you buy in computer stores, into a lump of white plastic.
If you PC and DATA is worth more than a UPS, buy the UPS, why rely on a twenty dollar powerbar.

So you are sure that there is juice where the PC is plugged in? Does the fan in back of the machine, in the power supply, work? Also check to make sure that the switch, that some power supplies have to set the volts to 220/50 as opposed to 117/60 isset to 117. This switch is in back on the power supply if there is one. It sounds like you have a definite power supply problem and theyb are cheap enough. Make sure you purchase a supply that is compatible with your system and as much wattage as you can afford.
