I am using a Umax PII 300. Here recently i have been having problems with my computer locking up at random during use sessions. I have not been able to deduce the reason for this so i am writing in this forum. I have 128 megs of ram(enough for most user progs), a vodoo III with the latest drivers, i use RoadRunner internet, a yamaha opl soundcard the latest DX, you name it. I can't figure it out for the life of me. I am thinking maybe a memory prob cause the comp will lock up after a certain period of time after using various progs. What are some of the causes for lock ups? The ones i can think of are IRQ conflicts, sys resources conflicts, device driver conflicts, DMA conflicts etc... i haven't found any of these things. Any suggestions?
