Computer fried?

  1. I recently had a problem with my computer. It randomly turned off and simply wouldn't turn back on. I thought it was a PSU problem so I replaced the PSU but no help. Later my TV(not monitor) broke, so I came to the conclusion that something was wrong with the outlet that they were sharing(along with some other things that wouldnt work such as phone charger)

    I replaced my old rosewill 400w PSU(came with case) with a brand new Antec SmartPower 500w PSU. However, now the computer still won't turn on. When I first put in the ANTEC PSU and turned the computer on, the lights/fans/cpu fan all came on but nothing showed up on the screen, it said "NO SIGNAL" which led me to believe something about the video card but everything was in right and plugged right. and some of the front LED's werent displaying correctly so i plugged out the front LED/power switch plugs from the motherboard and plugged them back in correctly. Now, the computer simply won't turn on just like before I installed the new PSU. Did my motherboard fry when the power messed up? Or what else can I possibly troubleshoot? As of now, the computer will not turn on or even act like its turning on. The switch of the power supply is ON and everything...I'm out of ideas, anyone have any clue?

    PC Specs:
    Rosewill case w/ 400w rosewill PSU(later replaced by antec smartpower 500w)
    ASUS K8N S754 Motherboard
    AMD Athlon 64 3400+
    1GB Muskin PC3200
    ATI Radeon 9800XT 256MB AGP

    (1) 120GB HD and (1) 80GB HD
    DVD-RW Drive
    Floppy Drive

    So if anyone has any ideas on what went wrong please feel free to post!

    try another power outlet first, then
    1. open up your pc and see if there's any burns or damage to anything,
    2. reseat all devices and cables
    3. plug in some speakers and see if you can get some beep codes
    4. swap parts with another working pc
    5. invest in a good quality surgemaster. no cheapie 5$ ones
    post back your results =)
