PC is AMD FX 8320 CPU 8Gb RAM , Windows 10 64b
I have a Asus M5A99FX PRO R2.0 motherboard. PC has its flashback LED blinking five Long flashes and Two short flashes then repeats when the PC is off, the green power standby LED is lit. The only way to turn the PC on is to turn the power supply switch off and then at the same time hold down the power button on the front of the PC and turn the power supply switch back on ,the computer with then Boot OK.
The PC will reset and restart OK it’s just when the PC is completely powered down that this behavior occurs.
I have already cleared the RTC and replaced the bios battery, re-flashed the BIOS. I’ve never used the flashback utility and I have nothing plugged into the flashback USB port in the back of the PC. Other than having to use two different switches to turn the PC on it works fine. I have also tried disabling the flash back USB port.
Any ideas?
