That's the wall that I've been hitting also . . . there's nothing out there that's compatible.
I just replaced all the parts except the mobo and the hdd. New psu, new cpu and hsf, new floppy drive, new BenQ, new RAM and new case fan. So I've pratically built 2 computers already and, from what you said, it looks like I'm going to have to build a third one because this mobo is on it's last leg. I'm talking sparks and smoke last leg.
Thanks for all your help zedman. It was much appreciated
