Okay, alioops, and SoccerFiend76, maybe my "general format for troubleshooting unstable computer" post was a bit abrupt because it is very likely that you have an o/s problem i.e. haven't installed the correct/most up-to-date patches for your hardware (maybe an AMD system? VIA, SIS, or FIC chipset MB? probably/definately need patches. check out the "bus mastering" section in the other/help area of the windriver main page.)

Like SoccerFiend76 said, an easy way to check for problems is to remove every card but video, and add em back in one at a time until you have found the problem.

This is also the method many AMD motherboard manufacturers reccomend. They want you to open your machine, remove everything but video, hard drive, and CD-ROM (please dont say "and keyboard" or "and CPU" We know. ) It dosen't hurt to clear the CMOS while youre thinking about it. Enter the BIOS setup, make sure that USB is ENABLED (they say to do this in VIA's Webpage) Install windows 98, do all the reboots, and on your first usable bootup, install the PCI bridge patch FIRST. this will make all your PCI and AGP devices work probperly. It will also install drivers for USB. Then do all the other patches, in what ever order you want. I think after the patches are complete, it is safe to disable USB again -- i dont know why it wouldn't be -- but don't quote me on that. If you are running an AMD cpu@350+Mhz, and win95, you will need another patch. Get it before you format, unless you have another computer.

After all sorts of software diagnostics, use my previous post as a loose guideline for troubleshooting unstable systems.
