    Hi,
    Here Is My Current PC Spec...
    P4 2.8GHz 512k 800FSB (OCed 5% to 2940MHz)
    ASUS P4P800S-SE
    512Mb DDR400 RAM
    64MB 8x AGP GF MX4000
    350w PSU

    Right, I Built The System Yesterday And was Running For 15hrs (Rebooting When Installs Finished) And All Of A Sudden it just shut down without any warning like we had a power cut.
    Now I have tried it and it wont even turn on except for the little joult on the fans and the LED on the motherboard. I have tested everything to narrow it down and i have found that when i remove the 4 Pin Plug which comes from the PSU to the motherboard the system powers on.. but obviously dont work cos the CPU needs that.
    Could This Be A Sign For A Bad PSU??? I have tried the PSU on my AMD Motherboard and it powers up fine but it doesnt use the 4 pin plug
    Any Ideas Will Be Tried??

    Possibly but i think its more likely that the PSU is a tad too dinky for that system ... when i fire up 6 or 7 Volcano fans, my HDDs never power up heehee

    Well, Actually i lied... i over clocked it to 3.3ghz .. so i suppose the VCore voltage made the PSU Blow cos when i tried the PSU in my AMD system it all powers up fine.. cos it dont use the 4 pin plug..

    Lol.... yeah, OCing does produce results such as that.................

    And you'll definitely want to upgrade your PSU if you're going to be OCing with that CPU.
