Video and USB Sharing Same IRQ - Help!!

[Spagina]

I'm having a problem with my video card in 3D applications. Namely a lot of crashes and hangs, thus the name of my rig down in my signature. I'm running Windows 2000 Pro and as I went through the IRQ List, I noticed that the video card and the motherboards USB were both sharing IRQ 10. I've tried everything to fix the crashing in 3D games and I'm thinking now that this shared IRQ between the USB and video may actually be the culprit.

I have one problem though, I don't know how I would go about changing the IRQ of either the video or USB short of disabling the USB IRQ in bios. If anyone could let me know how I could change the IRQ of either the video or USB in Windows or BIOS, please let me know. Here are my relevant computer specs...

AMD 1Ghz T-Bird @ 1Ghz (Not overclocked.)
MSI Kt7-Pro2A w/ v2.7 BIOS
Visiontek Geforce2 GTS 64 MB w/ v12.90 Beta Drivers (Driver version irrelevant, video has crashed with every Nvidia driver known to mankind and probably beyond.)
Hercules GameTheater XP w/2.02 Drivers
512MB Ram
WD 40 GB 7200RPM
Windows 2000 Pro SP2

If you can help me with this problem, I would be forever thankful. Thanks for your time.

Have you tried disabling the USB in BIOS to see if your problem goes away?

What HAL are you running? (ACPI or Standard PC)

Sorry I didn't include that. I'm using the Standard PC, I disabled ACPI when I first booted the machine and consequently afterwards whenever I did a BIOS update. I'll try either disabling the IRQ for USB or Disabling USB altogether and I'll see if it fixes some of the issues I've been having. If it does, I'll need to find someway to get the Video and the USB off of the same IRQ. Someone in another forum mentioned it was Windows 2000 assigning the same IRQ, but even in the BIOS under their IRQ options, you can see they assigned the display controller and USB Controller to the same Interrupt Pin Assignment. I need to find some way to get it off of it and let the USB roam on it's own IRQ.

I've been noticing this for awhile though, for some reason on my motherboard, the USB always wants to tag along on another devices IRQ. I have about 6 empty IRQ's on my machine, but no matter what order or what slot I put my cards on my motherboard, my USB always tries to attach to an IRQ used by a card instead of sticking on it's own. I may need to contact MSI about this.
