Question Strange Start up behaviour with i9-9900k and maximus xi core mobo

[Durwesh Naeem]

So recently i bought a i9-9900k and a maxmius xi core. So everything is working perfectly fine with stock, XMP I and XMP II bios settings, as i ran all timespy and firestrike tests, played the witcher 3 while streaming for a while. But i have a slight problem. when i am running XMP I or II bios settings mind you cpu is not overclocked by me. when i turn off my system, flip the PSU switch to off from the back. when i turn on while flipping the PSU switch on then pressing the power button on the case, system boots for a second shuts off and then turns on itself after a second then everything is working fine, this only happens when the psu switch at the back is flipped off( Also this issue does not occur when bios is at stock) . so for example if i shut down my system and do NOT flip the psu switch off and then turn on system from the case this issue does not occur. i have tried this with one DIM and also flashedback to the old bios versions still no help. is this a problem ?

Usually a PC does NOT unplug from the outlet or switch off from the psu switch, it is kept permanently on power. If you want your to pc have a long nice life dont do this anymore.
