BF 2042 Hard crashes (Reboots PC) no error after 20-30 minutes

I'm no longer able to play anymore due to the constant crashes. I can sometime get in a quick game , however I always seem to crash before finishing. It even crashes if I leave it running in the menu !!!

I have :

• updated drivers ( Graphics (inc. a complete clean install), M/board chipset , and anything else that I can update)
• updated windows ( even did a complete fresh install of Win 11)
• repaired systems files, clear DX Shader and EA App caches, repaired game files
• Excluded Game folder from Anti virus

I do not have this issue with other games ( e.g. played Fallen Order for well over 8 hrs , and no issues). I get no error messages ( just reboots), and I can't see any errors showing in Event viewer either.

 Attached DXDIAG file 

Any Ideas ?

Thanks
