I had a BSOD with Hypervisor_Error every time I close BF2042 and i didn't use Hyper-V.
After a lot of fail try with Windows Update / sfv check etc.. I finally decide to activate Hyper-V in the "Enable or Disable Windows features".
There was some updates and i had no BSOD after that so i finally disable again Hyper-V and since yesterday i had no BSOD after that.
I cross fingers, if it can help.
edit: after +48 hours of uptime en multiple BF2042 open and close, bluescreen again.
If ya did update bios, ya should load OPTIMIZED DEFAULT and SAVE them.
Sometimes a cmos reset (hard reset bios) is required.
Check youre manaul from MB how to cmos reset bios (by connecting 2 pins for some seconds, without power connected to youre system)
cheers
