I've tried it all and still can't figure out what is wrong. Any suggestions? Don't bother with obvious ones I've probably aready done it ie: drivers/ cleaning/ reformatting/ DX/ Via 4 in 1/ reinstalling/ game res/sound/ compatibilty in xp/ hardware acceleration/ reg tweaks/etc.

System

Chaintech 9EJL2 Apogee MB
Audigy 2
V5 PCI
512 mb
2.4 GHZ Pentium 4
XP OS

Thanks

Thanks for the attempt but all that stuff is old hat for me. Been playing the game for almost 5 years and have used all of the patches etc. Even complete reformats have not cured the problem and the performance from the glidos cannot match the voodoo 5 both in fps and picture quality. Thinking that my agp V5 was giving up the ghost I even brought a brand new PCI V5 and still whatever card I put in the problems return.

My question is what could cause either memory leaks or cpu spikes that seem to lock the computer? Various versions of DX have been tried. Shifted card positions and memory. Would another stick of memory help? Are there issues with Audigy and games and how would one fix them?

I'd suggest to remove all add-in cards from system that can cause problems (for example sound card) and try to run the game.
Also try to remmember what settings and configuration you used when game run well (i guess it did?)..
Adding RAM i guess won't help. Various versions of DX might cause problems, but i guess not in this case.

Well, I did try disabling the sound card but I guess it was not the problem as It continued freezing. Memory refernce errors are common when running the game.

Is the game trying to access any periperals when this lockup occurs? can you get it to consistenly lockup at the same point in the game? you probably havn't tried some of the crazy things I have back in the day.......  try removing your floppy drive.  seriously, it takes up a whole IRQ AND 1k IN THE LOWER 640k and another mem location and you probably havn't used it in 5 years.....  I can give you more......  The audigy COULD be the problem,  I just updated my drivers for XP which fixed a lockup on an opengl game I was running.  just because you disabled it, it doesn't mean the drivers have been removed from the equation......  also how does the lockup happen/work? does the screen freeze? or does it black out and reboot? etc.....
