I just formatted my HDD yesterday and I have installed all the correct drivers for the AGP. When I play Counter-Strike or 3DMark2001, it locks up after awhile for no apparent reason. This started happening yesterday so that's why I reformatted, but that didn't do anything. I haven't overclocked anything, although I have attempted to o/c my Leadtek GeForce2 Ultra but I have set it back to default core/memory. The highest I went for the core/memory was 315/515 which was unstable. Also, in the device manager the GPU and my SBLive! is sharing the same IRQ so I'm thinking it is that but this problem didn't happen until yesterday. Can anyone help me further? Thanks in advance.
