liquidsnakehpks: it is the problem 450w is what he has and the system requirement is over 500w [600w + at peak ] , hope he does not damage the pc more before its too late. i lost my motherboard with the same mistake [ i had 300w and the pc needed +450w]
cjrgreen: Very few PCs actually need 500-600W. That's a myth. Only high-end rigs that are overclocked or kitted out with high-end GPUs need that.
But a crappy 450W power supply probably doesn't even furnish 250W.
And there is still no evidence whatsoever that this is the OP's actual problem. Adfvising the OP to replace a power supply when it is not known to be the problem is irresponsible.
any pc these days which use a good graphics card requires 500w minimum, i have seen similar issues and replacing the psu with a better rated one was the best solution, hes pmed me the problem. Its a new system so a drive failure or a software problem is doubtful.
but i could be wrong, i have suggested from what i felt had the same issues with my own system.
