Sounds like a possible IRQ conflict. Check device manager for IRQ conflicts, or shared irqs; and try to disable whatever it is that's sharing IRqs (or try to change its irq if you need it. Try changing PCI cards to different slots if irqs still don't change).

If that doesn't work, run memtest to check for faulty ram. Could also be faulty power supply. If that's all fine then maybe Tomb Raider isn't finding enough memory (this can be very common on newer systems with lots of ram).

3DFX.exe is the Voodoo Graphics patch and Voodoo.exe is the Voodoo Rush patch. Only the Voodoo Rush patch works on Voodoo3, but it is recommended to play it in a DOS window under Windows98 to avoid the inventory crash. You machine should not freeze like that anyway, sounds like another problem tbh, not related to the graphics card.

Here's the system:

The cd is into a virtual cd drive, also, with glidos patch, there was the unfinished maps exe, that guy with voodoo rush patch works, but, with original tomb doesn't 😖

Also, I disabled sound on tomb raider setup and still the same error, I wanted to test it on dos mode, but, I don't have a cd to burn it '-' also there is a virtual driver for dos, but I can't make it load the tr1 cd >.>

You should get an original release of Tomb Raider and not use mounted stuff and glidos stuff for that computer. It should work (on most computers) if you do it the old way.
