went to sleep woke up the next day and i cant play games that use EAC anticheat. am fine on BE and everyother anticheat. I replaced my ram, reseated both ram and my gpu. updated my bio, reinstalled windows 3 times, deleted and updated drivers cant seem to have any luck with anything. i am fearing it is a CPU issue but i want someone to take a look at my minidump thats pretty good at reading/translating it to tell me whats wrong would be appreciated.

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
BugCheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
Else
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: ffff8e811e186e50
Arg3: fffff08ec4699000
Arg4: fffff8037a86d84a

Can you follow option one on the following link - here - and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD - that creates a file in c windows/minidump after the next BSOD
  1. Open Windows File Explore
  2. Navigate to C:\Windows\Minidump
  3. Copy the mini-dump files out onto your Desktop
  4. Do not use Winzip, use the built in facility in Windows
  5. Select those files on your Desktop, right click them and choose 'Send to' - Compressed (zipped) folder
  6. Upload the zip file to the Cloud (OneDrive, DropBox . . . etc.)
  7. Then post a link here to the zip file, so we can take a look for you . . .


also, what are specs of the PC? Dumps can't show everything attached.

that bsod caused by Easy Anti cheat itself

Majority of time, if a driver is mentioned in that text, its the cause.
Anti cheat programs like EasyAnticheat run at kernel level so it would have called CPU to stop.

If you give us the dumps, someone might be able to figure out why.

i can see epic/Easyanticheat has caused that error on other PC in past few years so what games are you trying to play?

Hi yes, to answer your last question first its any game that uses EAC that crashes for example: fort nite,ru st,ap x legends..etc. I am able to play games with other anitcheats such as, r 6,xdef ant,valo rant, and so on and so forth.

Here are my PC Specs:

11th Gen IntelR CoreTM i7-11700f @2.50ghz 2496mhz 8 cores.
Nvidia Geforce RTX 3060 ti
Corsair Vengance LPX DDR4 16GB 3600MHZ ram

Heres the minidump:
