I am having problems with crashes which seem to be video related. I have installed 4 diff. driver versions with no luck. Had the same problem with my previous mb and reassigning the irq's fixed it. I recently installed a new mb and cpu then did a clean install of win2k pro. As of right now irq's 5,7,10 and 11 are free. While irq 9 has sound card, video card, usb controller, network card and acpi on it. Clicking on their resourses in device manager does nothing. In the device properties the use automatic settings box is greyed out as well as the change settings button. I have tried turning off PnP OS in the bios and setting each cards priority irq but that didn't work either. Here is my configuration. AMD Athlon 950 T-bird Microstar K7 Pro Ver.1 512 megs PC 133 Viper 770 Ultra Creative Sound Blaster PCI 128 Netanywhere Lan Card 2 WD 6.4 gig HD (1)NTFS (2)Fat32 Please Help !!!

Put everything back the way it was, and turn the Plug/Play OS back on. Then, since you have a new MD, go to the MD website and download the latest Bios. Your MD was probably shipped with an outdated Bios. It's not uncomman, and Win2K needs a current version to operate properly.

Try going into the bios and setting the irq's manually rather than auto detect.

Oh sure, just flash the BIOS...I've heard THAT before. Don't risk it before you actually check the version first and find out if other people are having problems. The IRQ sharing thing is normal for ACPI systems--don't worry about it. MAke sure your drivers are the WHQL version before trying new and unofficial ones. After you've done that for both the video card and the sound card, try disabling the soundcard and see if that works. If it does it's because that SB sound card is a PCI hog and is consuming power. Next, try different PCI slots for the soundcard and toning down your video settings (AGP2x for starters).

OK Installed new bios. Still no luck. Also tried setting irq's in bios but the only options I have are PCI/PnP or ISA/EISA for IRQ settings. These crashes are sucking. Please Help !!!

Where are you experiencing the crashes? Is it in 3d games say for instance CounterStrike? This seems to be a big issue with AMD cpus and Nvidia video cards. I too have long suspected the problem is because windows refuses to use anything but irq 11 but haven't been able to change the IRQ's manually....someone must know how.

OK So far I have tried some more video drivers. No luck. Cleaned up my HD got 2gigs on C and 4gigs on D. Thought I had it once. Started in safe mode and all devices were spread out over the irq's evenly so I saved the Hardware profile and restarted using it. Well you guessed it right back to the same old settings again. Also tried deleteing APCI but of course when windows restarted it detected it and all the hardware and put it right back the same way. As far as when it crashes it could be most anytime with most any program. But the programs that seem to be most likely to cause it are Internet heavy apps., Halflife, Nero and some of my video editing software. This time I included a screen shot of my irq's as you will notice only irq 9 shows up as PCI all others show up as ISA. I'm almost positive it's an APCI problem wish I knew how to edit or turn off uae automatic settings. Then I'm sure I could fix it. Please help !!! P.S. Thanks to everyone who's tried to help so far. You guys are great.
