TMPGenc / MainConcept both hang my PC.

Hi,
I was wandering if any of you can give me some hints about this thing happening.
I am trying to encode to Mpg (both 1 and 2) a DivX AVI file on my PC.
I checked the AVI with VirtualDub and it says no bad frames. Even tried to explode the audio to PCM, saving to another AVI, but the problem persists.
The problem is that "randomly" (which means it can happen after a minute from the beginning of the encoding, or at few minutes from the end of the process) I get the XP blue screeen saying "IRQ_NOT_LESS_OR_EQUAL". No evidence on the event viewer.
I am using XP SP1, DivX 5.02, TMPGEnc 2.510 and MainConcept 1.3.1.
The funny thing is that TMPGEnc 2.55, set as single CPU, works. If I set it with 2 CPU, it crashes as above. TMPGEnc 2.510 with 1 CPU crashes, too.
MainConcept crashes always.
I was thinking about a DirectShow problem, I had directX 9 installed, so I reinstalled a fresh PC last night (only OS, SP1, windows update, and the SW's mentioned), but the problem persists.
Tried to "play" with TMPGEnc filters, reading the AVI with others plugins, but nothing changed.
Now I have a ATI Radeon 7500 series graphic card, with Catalyst 7.84 ATI drivers. Tried even with 7.83, this should not be the cause. Howewer I encode without preview-on-screen, to avoid this kind of problems.

System:
MSI 694D-Pro
2x866 PIII CPU's
784 MB Ram (2x128,1x512 PC133)
Sappiretech ATI Radeon 7500 AGP 2x

Just don't know what to do to fix this thing. Any suggestion appreciated.
Bye.

That error indicates a hardware or low level driver problem with your pc, not a problem with your encoder's. Make sure your motherboards bios revision is current. You should also make sure you haven't set your bios to an overly agressive performance setting. You should make sure all of your expansion cards are seated properly. Also check your memory sims. If you adapter cards show some discoloration on the contacts, use a pencil eraser on them. Make sure you are grounded to avoid static damage to the adapter. Their pretty hardy though, and can take a fair amount of abuse. If your not comfortable doing any of this, find a friend who is pc savy, or bring it to a pc repair shop.

It could also be a compatability problem between your PC and Windows XP. Is your PC store bought, or home made?

Last but not least, check your drivers. Specifically your audio, and video, to make sure their current.
