    Welcome to TechSpot!

    Can you give us the exact details on your PowerSupply please?
    It looks like it might be some generic PSU with no properly controlled power-output.
    If available, borrow another brand-name - like Enermax or Antec - PSU from someone (preferably 400Watts or over) and put that in your PC to see if that makes any difference.

    sure the psu came with case
    +3.3v 14amp
    5v 23amp
    12v 14amp
    5vsb 2amp
    5v 0.5amp
    12v 0.8amp
    this is all on a sticker on side of psu . no access to other psu

    As I said before, try another PSU.
    Yours unfortunately is a generic one with very limited capacity.
    Go buy an Enermax or Antec or Thermaltake of at leat 450Watts to cover your needs.

    I don't think a 450w PSU is needed for his system. A 350w should be more sufficient as long as it's a good & solid brand/model.
