Hi all,

I just took this in trade. It has no HD and only 4GB RAM (PC4-2666V) - otherwise, she looks ok.
My goal is to simply load W10 but it has an administrator BIOS password that I can't get past.

I've Googled this and read a dozen threads. I've tried a couple of Command Prompt fixes but no luck.
There's also a fix by unsoldering the BIOS chip from the mainboard - but I'm not going there.

On every boot-up it posts an error and forces a restart - but the error is different each time:

DRIVER IRQL NOT LESS OR EQUAL
PAGE FAULT IN NONPAGED AREA
PFN LIST CORRUPT
SYSTEM THREAD EXCEPTION NOT HANDLED
KMODE EXCEPTION NOT HANDLED
SYSTEM SERVICE EXCEPTION
KERNEL SECURITY CHECK FAILURE
ATTEMPTED EXECUTE OF NON-EXECUTE MEMORY

And every two or three boots, it shows a Windows 10 desktop for 5 seconds right before it reboots (Again - no HD installed).

I've never seen this behavior before.
ANY insight would be hugely appreciated.

Thanks, guys.

Seems like you have two problems.

One: You don't know the BIOS Password.
Two: The system seems to be generating memory page faults

Issue two might be more of an issue. You should probably try swapping out the RAM with a stick of known good RAM, but the RAM might actually be fine, and there may be damage to the motherboard that makes this PC a non-starter.

There's no jumper, only the bios chip.
The onboard diags say the RAM is fine - not a guarantee, but a start.
