Okay so I was pulling some hair off my motherboard and bumped the powercable that connects the PSU to the Motherboard (not the 4 pin one, the bigger one that is like 16-pin) any way the system all of a sudden just shut down all I can think is that I bumped the cable lose so I pushed the cable to see if I bumped it lose and turned the system back on and now I have a blank screen. The monitor acts as if the computer was sleeping (you know the power button turns amber instead of blue but the "no signal" never appears). Now when I mean no screen shows I mean their is no POST screen at all, it's pretty much dead. But the thing is the hard drive starts up spinning and all my fans start spinning (the 4 pin molex ones, and the CPU fans which are connected to the board). I tried swapping out videocards and that didn't do (and the one I swapped it out is from the system I am now using to post this). Also all my lights turn on (the power cn one which is connected to the mb). So all I can think of is CPU or Motherboard...please I need help bad! I need this system up and running in 11 days for a LAN party or else I am out $35 bucks. And I am almost positive the DVD drive works. But the PSU works as it spins up my fans and I have some case lights that did light up (I pulled them as I hated them but used for test). PLEASE I NEED HELP ASAP!
