Re: GeForce 7600 GS freeze: "irq 114: nobody cared"
Have you checked that the BIOS is in fact setting up the memory voltage correctly?? I have an ASUS Crosshair mother board with the nForce 590 chipset, and it would setup the memory voltage too low. (the memory timings it would setup correctly) So it would randomly hang or lockup.. Since correcting the memory voltage (It set mine to 1.9V, (Default) where as it should have been 2.2Volts), the system is now rock solid.. It worth checking out..
You will need to look up the specs for the ram your using, and setup the BIOS manually. That should correct the lockups..
