Battlefield 2042 Crashes whole PC?

Hello, which MemTest software did you run?

did you change any settings in bios after the update? if so try resetting the bios settings to default and try to launch, you could also try an older version of nvidia driver as well, since the launch of the 50 series nvidia updates have been reeking havoc in some systems, another thing to try is to go back to a previous bios version, what i am having to do my self because of launch issues hope this helps 

memtest86

it shouldn't be a bios issue, given it worked fine for 1.5 years, and the issue started 2 days ago, i then updated the bios 1 day ago and the issue persisted. i guess another thing would be to try removing nvidia drivers with DDU and reinstalling, though i dont believe i had installed any new nvidia drivers 2 days ago when the issue started...

could be your psu even though test show ok, could also be corrupted registry, have you opened command prompt as administrator ran “SFC /scannow” ? the right after run “dism /cleanup-image /restorehealth” , you can also try shutting down, clear cmos pull your ram out and reseat them, bios settings to default and try launching battlefield, Can you launch other games and play fine? 

and have you tried launching the game in clean boot? it very well could also be another program software running in background causing conflicts with anti cheat 

for me it randomly started closing the game after launch saying needed permissions and i had to literally do a clean install of windows, re download everything, trace every file pertaining to ea and battle and manually set permissions for each, i hope yours is lot simpler 

From my experience a PC resetting mid game is usually caused by a CPU or RAM error issue.

In my case the reset was being caused by overclocking RAM which caused memory timing issues. I also had to adjust CPU voltages for the memory controller before things became stable.

When my compy was unstable I would run MemTest86 and MemTest86+ all day long and my computer would pass the test with zero memory errors.

Then I downloaded https://hcidesign.com/memtest/ and my computer started throwing multiple memory errors during the test. 

Basically you launch a bunch of MemTest windows to speed up testing by using more CPU power. Be careful not to test more gigabytes of available physical RAM than your system has because MemTest will start testing the Windows Page File on the hard drive!

Press alt + ctrl + del to see how much available physical RAM is available. If you have 20 gigabytes of available physical RAM then you'd launch 10 HCI MemTest windows with each windows testing 2,000MB of RAM.

10 windows X 2,000MB = 20GB of RAM being tested.

Another thing to try is disabling CPU overclocking features such as AMD Precision Boost Overdrive, Curve Optimizer Voltage Offsets, and AMD EXPO™ Memory Overclocking Technology.

Thanks a lot for your reply! I ran your test with 100% coverage and received 0 errors, so it does not seem to be that...

Today I had a nice stretch of about 5-6 games of normal playing before my PC crashed, right after it crashed and started again I went back to BF2042 and my PC crashed in the main menu while search for a game, i repeated this 3 times and it always crashed while still in the main menu. This leads me to believe that IS some kind of overheating issue... I logged all data in HWiNFO for my last 2 tries but all temps seemed to be fine right before the crash, everything below 60C... 

After the final crash I also once again ran a full power stress test with 100% CPU and 100% GPU usage in OCCT and there were no crashes, with both CPU and GPU getting much hotter than during the crashes. I am so perplexed man...

If the system restart isn't caused by a hardware issue then that only leaves a software issue. The fastest and easiest next step is to plug a different storage drive into the computer and do a minimal install of Windows, Nvidia GPU drivers, and Battlefield. Launch the game and see if the PC restarts in the middle of the game.

This way you can save your current Windows install. I would unplug the storage drive with your valuable Windows install to prevent it being deleted on accident.

If the PC doesn't restart after a fresh Windows install then you've narrowed the problem down to a software issue on the old Windows install. If the computer continues to restart after a fresh Windows install then you've narrowed the problem down to a hardware issue.
