Re: What PC hardware diagnostic stress-testing freeware can you recommend?

Hi Mike,
Thanks for asking, where I was hoping to pick folks' brains to locate
specific debugging software to stress test the mouse and its drivers.

The mouse is a USB optical mouse, which is so worn that whatever
manufacturer was printed on the outside is long gone, but the "Mouse
Properties" in the control panel says the manufacturer is Microsoft
and that it's an "HID-compliant mouse".

But it's easier to just remember this instead:
o Win+R > control mouse
[I strive to do everything from the Win+R menu that I can.]

Looking at the same info in the Device Manager for the mouse:
Win+R > devmgmt.msc 
I noticed I have it set to be able to wake the computer but for the
computer not to turn it off in low power situations, which is fine.

The Sieber USB Device Tree Viewer tells me something completely different
though, as it says the "idVendor" is Lenovo, and the iProduct Language 
is "Lenovo USB Optical Mouse", which I didn't expect since the Device
Manager said it's Microsoft.  Oh oh. Logitech also shows up, so maybe the
USB tree view is "remembering" old devices since the app has been running
for days on end. Let me kill & restart it after clearing out all the USB
entries by running the Sieber "Device Cleanup" tool.

Nope. All three, Microsoft, Lenovo, and Logitech show up in the Sieber USB
Device Tree Viewer for that port. Go figure.

Well, what I'll do is swap in another mouse, but all my mice are old, so
maybe it's time to buy a new one.

Naah. You thought that when you saw the MemTest86 results. 

I saw that you said that it was 32, oh, more than a week ago, but I didn't
correct you 'cuz it didn't matter and we were working on tougher problems,
like solving how to set up the Hirens Boot CD over USB for BIOS instead of
for UEFI.

It's been 16GB all along. :)

Well, I dunno. I was just using the PC normally. For me, normal is not
gaming, nor do I run simulations, nor CAD design, etc. 

That was the whole point of the 24 hour test of "WhySoSlow", which was to
check the PC in normal conductions. For sure, I could have run any number
of CPU and GPU and RAM stress testers during that time frame which would
have maxed out everything, but the point was normal use.

Normal use for me is email, reading the news, editing some photos, editing
some MS Word documents, installing some software, etc. You know, normal
stuff.

I don't understand the pagefaults either. 
Why is it dumping stuff out of RAM if it has plenty of RAM?

I also don't understand the kernel responsiveness either bearing in mind
usually the first BSOD is related to a kernel error of some sort:

Hmmmmmm... I need to learn more about these page faults.
