OVERKILL
$100 Site Donor 2021
I've actually never lost a CPU, it's incredibly rare for them to die unless they are severely overheated and/or overclocked. RAM? Removed a dead stick from an HP laptop two weeks ago. Intermittent BSOD's, but not the same ones the OP is experiencing. Page fault in non-paged area is a pretty common one pointing to RAM.Over the years I have had similar type errors on a PC when something on, or, the MB itself is nearing death. My last one, the processor pooped the bed completely. It's no lie to say every desktop I have owned eventually went down this road, long after I kept it way too long. Over ten years in some cases.
The errors are intermittent. In most case it was not the main RAM, but as I stated before, the core ram. You can run tests, and most likely it will pass, until, well, it fails again.
I would be looking, at least be fully backed up and ready, for a new MB processor package.
Now, motherboards, had one or two outright fail, but several of them could be fixed with a limited re-cap (with the exception of the Nvidia chipset laptop ones, those had pin/package problems, not capacitor ones and were typically not worth trying to fix), as it's generally the capacitors that poop the bed and start making the board flaky. Have had to re-cap video cards too, for the same reason.
My oldest computer here is an 8088 from the mid-to-late 80's, was my first computer. It had something short out on the board though the last time I tried to fire it up, so it needs some work. I have a G3 Powerbook that still works perfectly, 1st gen iMac, a Slot-1 Pentium III system (which I posted pictures of recently), and a 486 SX/25 that I need to put back together. Hoping to find a 486 DX/4 100 for a retro gaming rig and an original Voodoo card.
My DD is still a 2010 vintage Mac Pro, lol, though it has a more recent CPU in it.
