My system has been freezing for over a week and I believe I have finally chased the problem down to the Nvidea driver for my Biostar mobo. This board was installed down here in Mexico because of the time and expense that would have been involved in replacing the original HP mobo. The system worked fine for about one month then I started getting system locks. Looking in the Event Log I found I could correlate the lockups with the following entries: The NVIDIA Display Driver Service service terminated unexpectedly. It has done this 1 time(s). So after a lot of time trying to decipher information on the nvidia web site I finally concluded I should install this driver: 162.18_forceware_winxp_32bit_english_whql.exe Question 1. Is this the correct driver for the GeForce 6100.m9? I guess if it is not I should get an error message. Question 2. Should I remove the current drivers. This is recommended by Nvidia, but if I uninstall the current driver and something goes amiss with the installaition of the new drivers will I be screwed? The local HP representative that installed my replacement board seems qualified and the company were very accommodating, but only the owner of the store understands and speaks English and I find it very hard to try and explain my concerns to his staff technicians in my limited Spanish. Plus taking it back means several days wait time for the repair. I have already lost a lot of time on this. What should I do? Install the above driver package? Thanks for any advice. Rich PS I note that this forum can also be accessed in Spanish. I think I will start reading the posts in Spanish and get better educated. The spanish one needs for PC computing is a lot different than what you use at the local cantina to order a beer.
