Pc keeps crashing with fatal exception at 0028:C0003702. I have tried latest drivers for via 4 in 1, graphics card, sound card, I have reduced video accelleration, and resolution. All with no result.
This happens after about 20 minutes. If you reboot immediatly it crashes imediatly, if you leave the PC off for 10 minutes or so it will then be al,lright for another 20 minutes. The cp;u is runninh at about 70 degrees. Any ideas?

Sounds like a heat problem, there are more chips than just the CPU that have fans on them in some systems. Video boards have them too.
You could very carefully touch the top of each larger chip and see if one is heating up way too much, you should check the fans and make sure the heatsinks have some sort of heat conductive material on them (either a grey flexy - spongy strip or some white goo - radio shack sells it).
If you got your computer used, maybe the jerk left off one of the heat sinks and/or fan, people will do that to save a buck when fixing another computer, they just grab it, put it on another system in a big hurry and then forget they did it later.
Of course, make sure all the fans are running and the heat sensor if it's external to the CPU is properly placed. Remember if heat sink compound isn't there, your heat sink will be cool (and the sensor if it's on the heat sink) and the CPU will be too hot.
A trick techs use is to spray cool spray at chips systematically to figure out which one is giving you trouble, as you said, you can let it heat up and then crash, then spray a large chip (not freeze it!) to cool it down and if it boots right up then you know what chip needs a heat sink (or is defective). Cool spray - radio shack.
You could try to re-seat any chips that are socketed, including memory sticks, and re-seat any plug in boards just for the heck of it.
Check BIOS settings for temp, maybe they are set too low? Also, as a last resort before going out and buying a new MB, reset the BIOS defaults, you never know.
After all that, go buy a new MB that will accept all your existing stuff, it's not worth your time after all the above is tried.
Let me know how it goes, I will check back.
