here is something I just thought of. I tried installing all the new parts to my computer the first time and I got what I am getting now (balnk screen, no bios, no beeps) so I put the old equipment back in and it worked fine. However after I tried it a second time the old equipment was doing the same thing. But if the psu was working the before I tried to upgrade and then still working after I tried to upgrade and put the old equipment back in wouldnt that mean that the psu is not the problem?
Also, I went to one of those wattage calculater sites and plugged in what info I had (which was the basic necessities, no cd or dvd players, and it also didnt count the monitor) it says that the most wattage I would need is 300. My psu is 450. So lets say my psu is functioning correctly (I am trying to borrow one from a friend to make sure of it) that would leave my cpu correct?
