  1. Hello everyone..

    When i'm using my computer,the computer suddenly turned off and it cannot be turned on back..
    There is no power led lights,the fans are not rotating even a 1milisec...
    This problem occured 2 weeks after i upgraded my gpu and i added 1gb ram on my pc
    This problem also occured 2 years ago when i'm playing game and that time my computer on a different mobo
    The 2 years ago problem occured after i have used my computer about 3 years(no change of hardware)

    After i changed the psu..the computer is working again.Now the problem is occured again with different type mobo,psu,and gpu
    The 2 years ago problem seem better,because the cpu fan is responding by trying to rotate(the fan rotates a very little,little movement)..and also no power led lights,only my monitor is on(the monitor is using power from my psu)

    Current problem is same but this time,there is no movement at all on my cpu fan..only my monitor is on..

    2 years ago problem pc spec:

    Intel D101GGC motherboard
    400 watt psu(no brand)
    Gecube ati radeon x550 GPU
    Pentium 4 3.00ghz HT
    512mb ddr

    Current problem pc spec:

    Biostar G31-M7
    475 watt psu(replaced the psu above about 1 year ago)(no brand)
    Sapphire HD5670(replaced the gpu above)
    Pentium 4 3.00ghz HT(same cpu)
    2 gb ddr2

    Anyone can help me?

    Thank you..

    Do you have another psu to try out? It sounds like the psu might have given it last breath power.
