: Does PC suddenly restart when it hits BIOS?
: Does PC suddenly restart when it hits BIOS?
So I built a new PC and it runs great, except one problem... The computer will randomly reboot to BIOS, with the M2 NVMe drive not detected. If the PC is fully powered down and then powered back up, the drive is detected and it boots as normal. This only occurs when the computer is idle (though maybe this is a coincidence). It might happen once every 3-4 days, it's frequent enough to be annoying but not frequent enough to interfere with day to day use. I thought at first it was one of the other drives (and this did help me weed out a dying HDD) but after disconnecting them the problem has not abated. I have tested the M2 drive with chkdsk, crystalmark, hwinfo and HDDscan and every single one returned perfect health reports. I have updated the BIOS to the latest version and checked the voltages on the RAM. I'm beginning to run out of ideas about what it could be beyond RMA'ing the Motherboard itself with the suspicion that it might be a bad NVMe slot. Does anybody have any ideas??

I have updated my BIOS to the newest version and checked the voltages on my RAM. Please tell me which BIOS version I used. Did you clear your CMOS after flashing the BIOS? If not, please turn off the power, unplug the computer from the wall, take out the battery, hold down the power button for 30 seconds, wait a bit, and put the battery back on. You forgot to say what kind of power supply (PSU) you had. If your unit came from an old machine, please tell me how old it was and what machines it ran before. How are you cooling your processor? Maybe loosen the pressure on the CPU mount so things work better. The computer is turning itself off sometimes when it should be on, because my M2 NVMe drive isn't showing up. If I wait until everything is completely shut down and then turn it back on, the drive will be found and it will start normally. When you touch the metal part of your case or stick out your bare feet onto a tiled (not wood) floor without carpeting, do you feel any strange tingling? That might mean you have an electrical grounding problem.
I changed to AMI BIOS version 7E12v1E, which was released on August 13th and has not yet hit Beta status (there are two other newer builds still in Beta). The CMOS should now be cleared. I'm wondering if it's safe to clear the CMOS again? My power supply is a brand new unit from this build: an MSI MEG AI1300P with 80+ Platinum and 1300W rating. The processor uses its own dedicated heatsink, which comes attached already. All temperatures on the PSU stay normal; I have never seen them spike in any monitoring tool (and even if they did, it would only shut down when idle for hours). There is no extra pressure on the cooling mount. I don't feel anything tingling or strange. Thanks for your help!
Some extra details... My RAM works with memtest (and it's new) I have two monitors; one uses HDMI to my GPU, the other uses DisplayPort. Maybe I can buy another drive and copy this one over as a backup. Let me do a long format on that drive now and see if fixing it works there. Maybe the factory setup is broken somehow? That feels far-fetched but it could be true.
