Computer died 2 weeks ago. It is a gaming rig that I built myself and it is watercooled. First thought that the PSU died and bought a new one. That did not fix theproblem. Next bought a new motherboard. It is the same model and everything as the old one was almost 1 year old (same as every other component in the rig). Installed the new motherboard and still nothing.
Here's what it does: After turning the switch on the back of the PSU off then waiting for a second or two. I then flip the switch back on and press the power button. The fans turn on and there is a high pitched beep and then everything dies again. If I jump the 4th and 5th pin on the PSU all of the fans turn on and run till I turn it off. When I first installed then new motherboard I hooked up the power to it and it turned on. The motherbard just had the CPU and Memory on it nothing else. It ran for about 5 seconds and then I turned it off again as there were not fans or anything else. I then installed everything and I get the no power problem again.
I have tried everything that I can think of. What am I missing? O' I also tried clearing the CMOS and taking out the memory and trying one stick at a time to see if that would help. Again nothing.
