4 BSODs while using chess program. "IRQL_NOT_LESS_OR_EQUAL"

Either of them flags an Emsisoft driver, I would suggest to reinstall or remove it while troubleshooting.

Code:

fffff880`09820378  fffff880`047caa60Unable to load image \??\C:\PROGRAM FILES (X86)\EMSISOFT ANTI-MALWARE\epp.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for epp.sys
*** ERROR: Module load completed but symbols could not be loaded for epp.sys
 epp+0x18a60

I'd wish there was a kernel dump available of the 0x50, or it is that I'm looking into a few things of the registry context that is volatile and thus not saved. The standard setting is to overwrite the kernel dump with each crash to spare space on the hard drive so the kernel dump is most likely already overwritten.


Please do NOT run any cleanup utilities while troubleshooting!

Axe0:
Thanks for the valued insight re Emsisoft anti-Malware. I will remove it immediately and run the chess program.
I have Emsisoft on 4 systems but it is conceivable that it could cause a problem on one system only. I once had a problem where Malwarebytes was causing a huge problem on only 1 of the 4 systems and had to remove it permanently from that 1 system.
What a miracle if the problem could be as simple as that but I'll know soon enough!
Also, I won't use any further Windows cleanups till this situation is fixed.

What memtest did you run? How many passes? A photo would be nice.

In case you don't know, we recommend MemTest86+ for a minimum of 8 passes, 8 passes with 32GB takes a few days to complete.

Diagnostic Test

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

I do not judge based on the current info.

If you did not run memtest86+, next recommended step is memtest86+
