i tried doing this to my GA-Z77X-UP5-TH, was i not supposed to do that? i got into the 3d bios, clicked F1, then F7 and confirmed to reset at which stage the machine switched off, then it went into a cycle of trying to start up, fan starts, but then it shuts off again, this went on for about 30-40 secs and i hit reset on the front of the machine, i could then get back into the bios again, to Peripherals, confirmed xHCI mode is set to Auto, then confirmed xHCI was enabled and EHCI Hand-off wasn't enabled, so i enabled it. then the machine went off again and back into the cycle but never actually able to start up.
i tried jumping the cmos reset pins, removing the board battery, disconnecting everything and trying to get any sort of different response but it always does the same thing. can anyone with more experience shed some light on what the problem could be (apart from me being a hacky noob)?
