Windows 7 Enterprise 64-bit
BSOD 0x00000124 seemingly random occurrences

BSOD's - STOP: 0x00000124 randomly several times throughout the day

-As this did not start at day 1 its very possibly a software/OS issues
-While testing the machine on 1 monitor over two days we did not experience issues; could be a video card problem?
-Faulty CPU(s)/Motherboard?
-USB 2.0 monitor hubs plugged into 3.0 ports?

Weve been experiencing frequent BSODs on this machine. While troubleshooting it, all Windows and Lenovo updates/driver updates were run. We did find a fault in the Seagate hard drive, and replaced it with a new unit. Memtest passed all RAM during 3 full cycles. We stress-tested the machine with Prime 95 (on all 32 CPU threads) for over 4 hours; no errors. While troubleshooting it, we did not experience a single BSOD.
After returning the machine back to the owner, the BSODs have begun again. Im wondering if its video-related as hes using 3 24 LCDs, while we only troubleshot the machine on a single 22 LCD. I updated the video driver using Nvidias current driver, as opposed to the possibly-out-of-date Lenovo supplied driver.
I also noticed he had some USB devices (monitor hubs) plugged into the 3.0 ports. We have experienced a few machines throwing BSODs with printers plugged into these ports, so maybe this is similarly related.

Final Thoughts:
Ive attached the .zip of the Windows 7 Forums Diagnostic Tool results. Im wondering if this is simply a bad motherboard we need to RMA. Any assistance would be greatly appreciated; thank you.
