    Welcome to TechSpot

    Looks like the cooler is no longer properly mounted on your CPU.
    Did you move the PC about recently, kick it in frustration, or did the dog perhaps lift its leg against it?

    Can you please fill in your PC specs under User Profile, at the top-left of this page?
    What type power-supply do you have? That may be too small.
    Did you check inside the PC to find if anything is hanging loose?

    The following signature stat what i connected so far. I unplug the rest (i.e CD-ROM, CD writer)
    Alright the problem is:
    1) I can on my computer as per normal and everything work fine
    2) During window , i keep receive notice like "Voltage under running below 4.5"
    3) Window may freeze out of sudden. (but i dun really know what causes it)
    4) I can play game (doom 3 , nfs ) , but not too much multitasking.(else system will freeze)
    5) My CPU is reading range from 50 to 65 degree *c
    6) when ever after freeze, i need to plug in n out the 20 pin ATX connector.(esle the system will not run)
    7) The strange thing is ... it work 100% if i plug in n out the 20 pin or shut down window properly

    CPU , Power supply or mb fault ?
    how to determine for comfrimation ?

    I think it is the dubious PSU from Channel Well (made in Taiwan). Its efficiency is only about 68%. The error-message about low-voltage indicates a failing PSU.
    Get yourself a better PSU from e.g. Enermax or Fortron, get a 400W or better.
