I've been having some problems with all the video cards I've tried on my motherboard except TNT2 M64. I've tried to narrow down what the problem might be. I've checked the BIOS and I saw an option that says Video BIOS cacheable. This is disabled by default. What does this mean? I have an MSI K7T Pro. Are there any other BIOS settings that may be causing these lock-ups? Any help will be greatly appreciated.
