My previous thread is pretty far back so to recap, I had had 50+ BSODs
with 5 or more different reasons given.

I installed the May update over my current win10 and then downloaded a
whole version and installed that over it. No change.

Debugging was hard because it sometimes crashes before it fully boots
and sometimes within 30 seconds. Worked fine in Safe Mode

So I used that source of media, I forget t he name, and re-installed
win10 keeping my personal files and nothing else, no installed programs
other than what comes with win10 out of the box.

Then I installed Firefox, nothing else.

Guess what? it still crashes with a BSOD. Sometimes before FF is
started. One reason was less than or equal and another was something
else.

I thought this should prevent crashes?

Unless it's hardware. I had run Memtest86 for 8 hours iirc before
with no errors. Last nght 17 hours with no errors, 7 full passes?

What else could be the problem?
Optiplex 755 Win10 Pro 8 Gig RAM Originally with Vista or 7
installed. Does that matter?

Should I try safe mode? What is the point?

Check the thermal paste between your CPU and motherboard. Sometimes it
can dry out and cause this kind of problem. If you don't have any
thermal paste around to re-do the layer, I've read that you can use
anti-seize compound as a temporary fix.

Forget that advice. I should have read your OP more closely. Sorry.
