XPS 8930, won't POST
Cascading problem began a month ago. Working normally, but after several hours walked into the room to see it restarting (black screen) multiple times. Eventually an error message about needing system repair. I rebooted and ran repair, all is well. About a week later,similar behavior - error about system disk overheating. Replaced the M.2 card as a precaution and installed HW Monitor to watch temps. Maybe a week later, used 8+ hrs, walked away and returned to find it restarting multiple times again, this time ending on black screen and flashing 2-2 amber code. Replaced RAM, no impact. Replaced MB - no impact. Just replaced PSU - no impact. Still flashing 2-2. Any ideas? Could it be the Intel processor?

Are all fans working, eg, CPU, GPU, case fan? What other drives are installed in this PC, aside from the M.2 NVME SSD? Have you disconnected SATA drives (HDD and DVD drive) from motherboard, if any, and tested again?
When you replaced the motherboard, did it already have, or did you install a fresh battery? Or did you just use the old battery from the original board? Make sure the battery is fresh before going any further. And reset BIOS to clear all stored errors:
- Reboot and start tapping F2 when you see the Dell splash screen to open BIOS setup
- Copy down all current BIOS settings, to be safe
- Power off, unplug power cord from rear of PC
- Press/hold power button for ~15 sec
- Open case and remove motherboard battery (check Service Manual for details)
- Press/hold power button for ~30 sec
- Install fresh CR2032 3-volt coin cell battery
- Close up and connect mouse, monitor and keyboard
- Reboot and test again...
If you still get the 2-2 blink code, are you sure the replacement RAM is compatible? Dell systems can be very fussy about RAM, even if it appears to have the right specs.Assuming RAM is fully compatible and you still get 2-2 code, repeat above steps, but remove all RAM except the one in 2nd slot from CPU after step 6, and before doing step 7. Test again at step 9. Then repeat again putting each RAM module one at a time in 2nd slot from CPU between steps 6 and 7, until you test all of them, and/or identify a bum module...
If you can't identify a bum RAM module, run the diagnostics. Reboot and tap F12 to open the menu. Select the diagnostics option and run all of them. This can take a long time, so be patient. Review the report when diagnostics are done, and copy error messages, if any.
