My system shut down and would not reboot.
The red light on the mobo showed, but when I switch the case button, the green light on the mobo flashes and the system shuts down.
I removed all hard drive power & SATA connections, ram & video and then attempted (after removing the power lead & wating 30? seconds) with the same result.
I also removed the cooler from the cpu, and installed a passive Coolermaster Hyper 600 to isolate an issue with the old fan, but still the problem remained.
I then jump started the psu with everything disconnected except a case fan and the psu started but with a really high pitched whistling sound. I tried this a number of times but the very loud whine was still there.
Not sure if its relevant, but I have kept my system running 24/7 for the last couple of years since I built it and had no previous problems except a fairly new HDD that has corrupted itself twice in the last week (now awaiting RMA)
Any ideas? Is the issue mobo related, or could this be my psu at fault?
