The power supply is not the problem so I think it is a faulty video card, monitor or the motherboard. Try switching monitors first.
If you have the motherboard installed properly with standoffs in the case the board would not short out. Covering the spots where the motherboard makes contact with the screws with paper, cardboard or electrical tape is not needed in my opinion.
thanks for the help & info, but see I assembled the PC outside of the case exactly as it is now just that now it is inside of the case...when it was outside everything worked, it booted up and I was able to use the computer normally... now the only difference is that I tried different monitors (outside the case I used an old CRT, inside the case I moved it to a room to use an LCD screen...but would that really make it not even boot?..)
If it works out of the case, but not inside the case..what are my options? The only thing I can think of is that the case is shorting something ?
I SWEAR this computer is WEIRD!!!!!!! .... I left it as it was over night, now I go to turn it on and guess what....it works FINE now..? w-t-heck ? haha, man I wonder how many updates will I have to make on this post (it is kind of annoying to myself, so I know it must be annoying to those of you trying to help...I appologize)...I will post if things go south again and I cannot figure out anything
