BSOD After ESET Update to NOD

[PleaseHelpMev2]

I'm not sure if this is the correct section so if it isn't please move it. I aplogize if it isn't i am just running out of ideas & need some kind of help!

On my Brother's desktop that is on windows 8.1. ESET Smart Security is the A/V on the PC. Upgraded to ESET NOD & when it asked to restart. The PC will boot & get a BSOD, then go into automatic repair. I've tried all i could think of to fix this & get it back to starting up as normal. I tried system restore but apparently ESET is preventing that & we don't have a Windows 8 disc of any kind. the Desktop was sent years ago as is. I tried googling to see if there were commands using the cmd to disable or delete ESET but i couldn't come across anything!

I'm running out of ideas to be honest & losing hope that i've completely just ruined his PC. The PC boots, BSOD's then goes into automatic repair. That's as far as i can get & i can't find any fixes to at all on my end. I'm assuming if it were that easy i just need a way to turn off eset or uninstall it even, but i can't get the PC to even boot into it's OS/Desktop at all. Please, If anyone know's a fix i will try anything at this point!


EDIT: I also cannot boot into safe mode either as it also crashes/bsod trying.
