Hi, I am having problems with my motherboard I just bought. I am building my own PC and I bought everything brand new. When I installed everything(following the steps in all manuals very carefully), my new computer didn't start, like not even the fans of the case and CPU started working. However my motherboard LED light was on, so I knew that there was power applied. When I pressed the power button on the case I heard a loud and quick noise, like something shortening out. I unplugged everything and trased back all my work. Nothing was wrong, except the fact that I might have overpowered the motherboard. My motherboard powers through two outlets- one 24-pin and one 4(or optional 8-pin) outlet. I connected the 24-pin power cable from the supply to the board and then I wasn't sure, if I should use the 4-pin connection or the full 8-pin one. My PSU had both options. So I did used the 8-pin connection. Is overpowering possible, and if it is, does that mean that my board is toasted? I dismounted everything and nothing was burned, shorted or just plain looking wrong. I corrected my mistake and the computer didn't started again. I don't know what to do. I ask for help from anyone. If you need more information please let me know. Thank you.
