I recently encountered a strange problem:
Sometimes, my PC won't boot. Pressing the power switch does nothing. I checked fans etc. After some time (I replugged the device multiple times, turned the power pack switch, ...). It starts again! Both in BIOS and using software tools, all voltages seem to be fine, once the machine is running, it works as expected.
I know this is no details explanation, and I am looking for some hints on how to figure out whats actually wrong. Could the reason be that I disconnect power supply every night (using an extension cord with switch)?
The power pack is "Cooler Master V750S Semi Modular", and the mainboard "GIGABYTE GA-Z97-HD3". If you need more information I can provide it.
Edit: BIOS is up to date
