So I bought and installed a brand new PSU, this time around that seems to have solved part of the issue, now with my OS drive (seagate 250GB) the system will POST, but after the verifying DFI data, it simply hangs. I borrowed my friends 250, which was installed on the same motherboard as mine, and now it POST's then I get the boot error (even though the drive is loaded with Windows), after it attempts a network boot (even though the windows DVD is in the drive). When I attempt to access the BIOS, I get a blue bar running across the bottom of the screen, and nothing else loads, the LED displays 75, but I have not been able to locate any documents regarding these error codes (Phoenix BIOS). I have pulled the jumper to clear CMOS, but even after doing this it does not seem to affect the system at all. There is another jumper for clearing CMOS, but it is in a rather inaccessible area. Worse thing is that the companies website does not list any of this type of motherboard. dfi lanparty dk 790gx-m2rs What should I try next?
