Ok, I got this computer from some one who had a power surge and frted the power supply, he filed an insurance claim and got a brand spanking new one, heres the deal I bought a new power supply not made by dell, it said that it would replace the one I had though, Heres the problem, the computer seems to be running but the screen will not come out of standby, It wont show anything. I wen as far as replacing the video card with a gforce 4 i had laying around. Any thoughts?
