Acer Predator PTX17-71 randomly locks up / crashes / freezes

I'm about 1.5 years in on my laptop so it is out of warranty, and I've started experiencing consistent lock ups - the screen remains visible, everything stops, audio will hang and repeat and stutter with whatever 1ms clip was playing last, and the only way out is to hold down the power key to shut down.

When I restart it will be usable for an unpredictable amount of time, after which it will happen again.. sometimes within a few minutes, sometimes I can play a GPU intensive game for 2 hours and not have it happen. I do seem to be able to reproduce it if I launch a browser, start playing music, launch Cursor, try to do some work, then it generally usually lock up.

I've done a lot.. I used Windows event viewer to find the last entries before the 'Critical' event that indicated the unexpected power failure. Initially I saw:

ACPI thermal zone _TZ.TZ01 has been enumerated.

_PSV = 0K_TC1 = 2_TC2 = 3_TSP = 4000ms_AC0 = 0K_AC1 = 0K_AC2 = 0K_AC3 = 0K_AC4 = 0K_AC5 = 0K_AC6 = 0K_AC7 = 0K_AC8 = 0K_AC9 = 0K_CRT = 383K_HOT = 0Kminimum throttle = 0_CR3 = 0K

which the 0k indicated Windows wasn't receiving valid cooling policy data from ACPI. I reinstalled Intel's DPTF (Dynamic Platform & Thermal Framework) drivers from the Acer site and I think that cleared that up. I also reinstalled Predator Sense. I also purchased a cooling fan to sit under the laptop. None of this fixed the problem.

I eventually saw through the HWInfo64 utility that the temp was being reported properly

So I chased this down, eventually proved that the temp and power were ok, then also saw some networking related errors in the event log:

Connectivity state in standby: Disconnected, Reason: NIC compliance

and The driver \Driver\WUDFRd failed to load.Device: PCI\VEN_8086&DEV_A71D&SUBSYS_167B1025&REV_01\3&11583659&0&20Status: 0xC0000365

So I chased that down as well. Here's what's been done:

  • I updated BIOS to 1.09 (latest), reset to defaults
  • I reset Windows (kept files), it even locked up while resetting at one point
  • I opened up the system and tried to swap out the RAM but I didn't have compatible set, so I just reseated the RAM
  • I tried swapping the location of the M2 drive on the motherboard, but it wouldn't boot that way so I switched it back to bay 1

Next I plan to do a full reinstall of Windows using a USB image, basically try to wipe the system back to basics, but I'm not hopeful.

Any other ideas or suggestions for what I can do to salveage the PC? It has some nice gear.. a 1TB M2 drive, 64gb RAM, a GTX4090 video card, I hate for this thing to become a doorstop and waste my $2500 spent. Are there repair options? Or sell it off piece by piece and by something other than Acer?
