Well about a year ago i bought a graphics card for my computer, and after i stuck it in my computer and tried to start it up, it wouldn't. So i called best buy and asked them what the deal was and a guy told me i must have not has a large enough power supply to support the card, So i went and bought a bigger power supply, hooked that up, problem solved.
Well recently i reformatted my computer sort of on accident and now the graphics card acts like it did before i bought my new power supply, when its in my computer just won't boot, and when its out everything runs fine. I did not take my new power supply out or remove/add anything i didn't already have when it was working.
My question is, Why isnt my power supply working right
