System freezes. Driver problem

My system freezes only when i use video encoders(main concept, tmpgenc etc...). Occassionally i get the chance to error report and microsoft identifies the problem as being caused by a device driver(unidentified). I can't track down what exactly is causing it and i don't get a blue screen error message.

Otherwise the system is stable.

Tyan tiger mainboard, twin athlon 2000+mp cpu's. Mercury Nvidia geforce 2 mx graphics card, creative sound card, Samsung 120GB hard drive, Pioneer DVR 105 and 106, 3COM 3C920 integrated fast ethernet controller.

I know twin cpu systems can be funny but this really is the only problem i have.

The graphics drrivers are signed.

Any help would be appreciated.

 

have you updated your drivers i know nvidia just had an update recently

 

Yeh done that. Thanks.
