XP BSODs, restarts... for a year. Help?

I don't know if this will help - but it might. I
installed and re-installed ABBYY FineReader many times.
It kept halting my computer (XP Pro/SP1) with the BSOD.
the ABBYY helpdesk took about a week to answer each of my
emails. I finally kicked it off my system and got
TextBridge. It seems that ABBYY is in Russia, of all
places, and they simply couldn't fix the problem.

Greetings techies and smarter-guys-than-me:

I have been having a problem with my PC for a year now
and
have done all I can think to do to cure it. The problem
is that XP will randomly stop with a blue screen,
perform
a "memory dump," count to 100 and restart. It happens
regardless of whether I am online or off. It happens
irrespective of what software I am using. The specific
message changes, but is
usually "IRQL_NOT_LESS_OR_EQUAL."
The message screen sometimes recommends "try changing
video adaptors" or "If you have recently added new
hardware or software, try removing it" but I haven't
added
anything. Sometimes it recommends disabling "advanced
chipset features such as ram caching or shadowing" (or
something like that)--disabled in BIOS; no change.
This
is a since-day-one problem.

The only equipment the upgrade advisor complains about
is
my Acer scanner. I removed, disconnected and
uninstalled
it... no difference.

So far, I have tried: Changing video cards (disabled
the
onboard video and installed a geforce4 PCI card, which I
have re-uninstalled); changing ram modules and
configurations (every possible one); scanned for viruses
(obviously); altered BIOS settings about a dozen times;
updated the BIOS; sought out updated drivers for all
hardware; run Windows Update pretty regularly; upgraded
to
SP1; run all the Windows maintanence stuff... that's
about
all I can think of.

Here are three stop errors I got just this afternoon:

Error: "IRQL_NOT_LESS_OR_EQUAL."
Technical information: 0xa (0x2, 0x0, 0xb8eoo1cc,
0x8050060b)

Error: "IRQL_NOT_LESS_OR_EQUAL."
Technical information: 0xa (0xf9a0e1fe, 0xff, 0x0,
0x8052f02f)

Error: "DRIVER_IRQL_NOT_LESS_OR_EQUAL." [notice the
difference here]
Technical information: 0xd1 (0x8051, 0x2, 0x0, 0x8051)
[yeah, 8051 twice]

Error: none
Technical information: 0x8e (0xc5, 0x805321a2,
0xf7b2ec4c,
0x0)


Anyone have any ideas? System information follows (much
