Random Game, Video Lockups

[kake]

I have an odd issue. On the computer I have hooked into my living room projector, while watching DivX or other video for more than an hour, occasionally my computer will lock up solid requiring a reset. When trying to play a game, such as FarCry, sometimes the level will not even load before a lockup. The longest I've been able to play FarCry or nearly an other FPS was about ten minutes before the computer crashed. Interestingly, Splinter Cell: Pandora Tomorrow runs without a hitch.

I've never had a lockup within just simply Windows or any 2D, non-video application. Specs are as follows:

Windows 2k SP4 all updated
Athlon XP 1800+ Thoroughbred B [not overclocked; 133 FSB, 1.5 VCore]
Asus A7N8X Deluxe PCB version 2.0 [nForce 4.27, latest drivers for SATA, NICs, etc]
3x 128MB generic PC2700 DIMMs at 2-3-3-6 [2.6 volts(?)]
LeadTek Winfast A6600 TD [with ForceWare 71.84]
Maxtor 20GB 5400 2MB cache HD
Western Digital WD800 80GB HD
Samsung DVD-RW
Samsung DVD reader/CD-RW
running Ad-Aware, Spybot and Kerio Personal Firewall for protection

I appreciate your assistance.

Hmm, interesting. Have you tried many other games? What Patches are you running Far Cry with and have you tried either stock 1. or the latest patch version?

Anyone else have any ideas?

I would make sure tht your video card isn't overheating, as well as opening up dxdiag, and under the display tab, disabling all 3 direct modes, then re-enabling them all.

It's less likely, but it could also be a bugged version of FarCry. I have a version that I got almost to the end, but the level would not proceed. I've downloaded the patches, updates, etc and it still would not work right. I never found the answer to the problem.
