PC producing a large number of blue screen errors

[Darkans]

So I've had this PC for a while and recently it's been blue screening a lot, sometimes it refuses to boot after just giving me more blue screens. Originally I thought it was the ram so I've tried various combos of all the sticks but nothing seems to work.

Errors including exception not handled, critical process failure, bad pool header, kernel errors and the like. Any ideas? Faulty windows install perhaps?

Have you checked your ssd or hdd?

I have no other drives to plug in to test atm, now it's not booting at all just giving me the same error "critical process died". I'll see if I can get a different drive to test, thanks.

What's the total spec?

Is the system clocked at all and if it is set it back to stock/defaults.

Remove all but one stick of memory and run memtest - check each stick (will take a while).

I can't run anything atm it won't even boot in safe mode, just keeps saying critical process failed so I think the drive has gone, I'll be able to test it tomorrow and will update then.
