I was trying to screw in a cover on the back of the case and it dropped out. I think it touched something when it slipped and the computer shut off. I then turned it back on and it went on for a few seconds and then shut off. It just keeps doing that everytime I try to turn it on and the standby LED turns on while I turn the PSU on then when I hit the power button a red light comes on and then it shuts off everytime. I hope someone knows a way to fix it or if it is for sure dead. Thanks
