I have been having this problem with my computer locking up several times each day for the last several months and nothing seems to help. I have changed the cpu twice, (celeron both overclocked and not). I have changed the memory,gone from Win 98 to win 98SE. Changed harddrive and and checked it out with Norton Utilites several times. The only thing I haven't changed is my Video card a Geforce 2MX 32 Mb clone which I have up dated the drivers on a regular basis. I am running this on a Abit BH6 V1.2 motherboard. Could it be the Video card as I installed it just a few months before I noticed this problem?
