: 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.
Here is your motherboard link: https://download.msi.com/archive/mnu_exe...WKWIFI.pdf Did you check if that manual fits what I found? How did you put in the RAM? The guide says to put the first piece of RAM into DIMMA2 (see page 28). Also, read those other key notes on the site.
Now I want to check if Reliability History or Monitor are recording any error messages or alerts right when a blue screen happens. Are they keeping track of those details right before or exactly when the crash occurs?
Maybe it's just a physical connection issue between your NVMe drive and the M.2 slot. Try reconnecting or unseating the drive, making sure the M.2 screws or latches are tight on the back of the card before you put it back. If that doesn't fix things, try using another M.2 slot instead. You don't need to move the drive or reinstall Windows; just make sure everything is connected right.
I think there aren't any blue screens of death right now—it's just a power loss (though I've never actually been awake when this happened). The Event Viewer and other tools show nothing at all, and there are no log files to read. That was my next move: I'll send you the report back later, but it might take a few days before the issue shows up again because it's super inconsistent.
