I am running Win2K with all SP's and updates. System is 1.0g Intel P3 with 512 ram. While watching live Streaming Video on Window Media Player 9, system locks up solid. Key board is inactive-must hard boot. I have checked for all file associations (to my best ability) and all updates and Codec's for Media Player. Also, monitor will intermitently go black, like I reset it, for two-three sec's and come back on. No error mesg in Event Viewer. Video Card is NVida 64meg card. The drivers should be up to date. Any input as to trouble shooting would be appreciated.
