Hello. I’ve got this issue in my pc for a few years now (I’ve had this pc for last 5 years). My pc will start and then immediately shut down and same thing keeps on repeating as in a limbo. To fix this, I move/ play with the 24-pin connector (psu to mb main cable) till it comes out of this limbo and starts. Sometimes it starts off and display comes, but most of the time the display is blank and I’ve to reinstall the BIOS cell to reset it and the display comes after this.
Often times, while working or even while doing normal internet stuff, the pc will suddenly shut down and then won’t start and give this same problem. Also, sometimes when I do the normal shut down, the pc automatically starts up after 3-5 seconds and I’ve to hold the power button to shut it down.
I’ve narrowed down the problem to be either with my PSU or the Motherboard but I can’t put my finger on which one it is. Please help me with this issue. Thanks

– disable the auto-restart feature in Windows
– check your CPU temp readings in the BIOS. If the temp is too high, you’ll have to determine the cause (usually a dust-clogged or improperly seated heatsink/fan).
– flash to the latest available BIOS, version 1408
– manually configure your BIOS settings, do not simply “load defaults” & leave it at that
