Question Windows 10 BSOD: NMI_Hardware_failure

[Emyrryl]

Greetings,
I've prowled and lurked through here for various answers to PC issues for years and am usually pretty successful with what's already been asked.
This time I am in a position where I am wracking my brain and Would need some specific help looking into what recently started causing these blue screens in varying frequency about 6 days ago. I've tried a few things ( gone through most of my used drivers reseated hardware etc etc.) Trying to figure out the cause of this recently started bluescreen. The last step being removing what I had thought was a faulty stick of ram due to staving the blue screen off for about 24 hours. Below Are both of the most recent crash dumps
(Both crash dump addresses are as: NTOSKRNL.exe+3fdaf0)
Any help is greatly appreciated

Update with additional info: I have received a new error when attempting to POST out of bios of a "USB device over current"
Which I isolated to the madkatz R.A.T. Mouse I was using, I am going to dig into this further, if this is the cause I will further update this.

In both dumps the nfextlag.sys driver would appear to be at fault. It's referenced in the lead-up to both bugchecks, in fact it's the last driver call before the bugchecks. Both dumps show considerable networking activity in the lead-up to the bugchecks too.

The nfextlag.sys driver is a component of ExitLag, which is described as a 'virtual VPN', that fits well of course with the copious networking activity we can see. The version of nfextlag.sys that you have installed is almost 9 months old now, dating from Oct 2023...

I would advise contacting ExitLag for an update or for assistance. Alternatively, remove ExitLag from your system completely.

Going to try and update first, if I receive it after updating uninstall time. I couldn't stay in the machine long enough to prowl through the dump. I owe you a beer, mate, thank you for the response, I will update on next blue screen or if a few hours pass with no issues!

Absolutely owe you a drink of your choice, reinstallation has stopped the issue, Both ram sticks are back in and things seem to be on the working side. Thank you, Ubuysa.

No problem, happy it's working.

A drink of my choice? Well, a bottle of Louis XIII de Remy Martin Rare Cask Grande Champagne Cognac would be nice, thanks. You should be able to pick one up for around $35000.....
