Re: PC turns off after few seconds after on button
Anything 4 seconds into the boot cycle is not even hitting windows yet, so ignore anything on the software side. It turns ON after 8 seconds by itself?
If it shuts off and you have to turn it on again after 8 seconds to get it running then it sounds like a power supply issue, it isn't providing enough power on the cold boot.
If the motherboard is shutting down after 4 seconds then powering itself back on 8 seconds later, the motherboard needs replacement.
