Problem description: I got a free Dell 7480 from work. After buying a new battery and NVME drive for it I can't seem to figure out why it keeps randomly shutting down. The longest I've had it going is about 10 minutes but sometimes it gets to the point where it can't even get into Windows. It will shut off completely then power back on as if it was booting normally. Seems to maybe get worse once it's been on for a while which makes me think thermal issues. However looking at the Thermal Log in the Bios shows no events, there are events in the Power Log though. Attempted fixes: - I bought a new battery, on the off chance it didn't like running just off AC. - Bought a new fan/heatsink module (I used the included pad which had no cover, just in the box? Maybe that's not good?) - Reinstalled Windows - Checked in HWiNFO for temperatures, they are high but it's not consistent when it shuts down. Recent changes: It had no HDD when I got it so it should be fresh, I updated as many drivers as I could before it would shut down. -- Operating system: Windows 10 Pro 64bit. System specs: Dell 7480 with an additional 8Gb of ram added, WD SN570 added as well. Location: New Zealand. I have Googled and read the FAQ: Yes.

I'd run https://www.memtest.org/ to check the RAM health. If it loses power during the test I'd disconnect the drive and try the test again.

I ran Memtest86+ for nearly 11 hours and it passed 11 times, no errors...I assume that means the ram is OK?

Would it be worth trying a different OS? I mean to do diagnostic stuff. It’s clearly something related to Windows as was happy to stay in Memtest for 11 hours without a reboot.

If you can get into Windows I'd try running https://www.hdsentinel.com/download.php and see if it sees any issues with the drive. You could also try booting from a version of Linux on a USB if you want to. Was the drive disconnected when memtest was running?

Sorry, should I do that? I'll need to wait for a cold boot (seems to be usable for the longest time from a cold boot, which led me to thermal issues but who knows now) to give that program a shot, will look in CrystalDiskInfo as well.
