Hey guys, i have a bit of an issue, i was moving my rig from one case and packing it in to another, but when i tried to boot up my i wasn't getting a reaction on my screen, fan's were spinning, but no signal, i restarted a few times, then i checked my PSU, turns out a didnt connect it correctly, any way when i set every thing up the Windows boot logo freezes then i get a flash and the "blue screen of death" for a second and my PC restarts, im running Windows 7 Ultimate 64bit, i know its outdated, but i like Win7, can any one tell me how to resolve this issue without re installing? I tried Win repair but that never works, thank you all in advance.
