About a few months ago my older laptop started freezing without bluescreen after a few minutes to a few hours after booting up. The weird thing about it is that once I hard restart after the freeze it will never happen again until I reboot/shutdown the computer, so if I keep it running after a hard restart it never freezes.
Things tried:
Fresh Win10 install
Memtest
Event log just shows the hard reset

CPU temp is high because its doing a Windows feature update in the background for the last hour.
Try stress testing the GPU.
If the laptop freezes and an audio file is playing does it keep playing, stop, or repeat a short snippet of it?. (can be seconds or a few milliseconds, which sounds metallic)
Sometimes audio stops immediately, sometimes audio continues playing for a few seconds after screen freezes and then stops.
I'll put the GPU stress testing.
Yes, try this.
Could also be an issue with the SSD, try using CrystalDiskInfo.
Hmm, guess not. Looks like both drives are fine. What is the CPU usage like when the freeze happens? Open task manager and leave it in the background right after logging in.
Are you able to select whether you use optimus or either graphics chip in the BIOS? If you can, try force it to use either the integrated graphics or the discreet one.
No.

About 5 hours of Nvidia gpu stress testing, no freeze.
Try youtube videos with furmark in the background to keep the laptop using the dedicated chip. Furmark doesn't test the video decoder hardware which can cause problems.
Currently been running for over an hour without freeze. Furmark + Firefox with 1080p video + Chrome with UHD 60fps video.
Currently I'm thinking its the motherboard, but don't want to spend 100$ on a new one unless im sure.
Sounds like an issue with power states, try updating the bios before replacing the board.
I've had bad ram produce this exact issue before, albeit was a desktop. Just like you I ran memtest with no errors but after swapping in known good ram the problem seemingly evaporated.
