PC wont turn on after power outage

    We just had a power outage this morning and when it came back on I tried to start one of our computers but it wouldn't turn on. I opened it up and did a visual inspection of the mother board and I don't see any damage (popped capacitors). It doesn't smell fried either. I hooked up to another PSU and it still would not turn on. I checked all connections and they are fine. The light on the motherboard lights up showing it is getting power from the PSU.

    Any idea what would be blown on this computer? Thanks in advance for the help.

    disconnect all cables to drives, remove all cards & ram except for videocard & 1 stick of ram. reseat those 2. if have onboard video but using a card then try onboard video.

    From my orginal post...
    PSU is not the problem.

    **Side Note** ddp can you point me to where it says that you cannot have links in your signatures. I have found info that says no HTML, but links are ok. As long as their are not to pirated content or contain affiliate codes.

    Well I have already moved the Hard Drive and RAM to another computer and those are working fine. The computer ran our time clock at work so it needed to be running. Probably right about the MB. On the few blown MB's I have seen one or many capacitors have buldged and leaked. I didn't see this and the light worked so I wasn't sure. Well its not worth the trouble of getting a new MB. These are 4-5 year old eMachine Celrons. They have servered our purpose. Time to go search the net for some cheap PCs. I should have ordered a few more of the $69 ones I found 6 months ago. Thanks for the help.

    yes also dell sell some cheap ones for $200 including a flat panel 17" display and a core 2 duo e4500 which is pretty decent and plus you can do the "pin mod" on them to run on the 1066 mhz fsb
    -hope this helps

    buldging capacitors are not caused by power fluctuations, they are usually caused by the "bad formula" that a scientist stole and used in capacitors a few years back. -im1992
