I was reading the Random restart post and I am having the same problem. At this point I took the first suggestion and unchecked the auto restart. I am running XP. There is no rhyme or reason to this happening. I checked the device manager and everything looks fine. I took a look at the performance and that all looks good. I have sp2. I tried to download sp3 and it would not take. I’m guessing this may be a driver problem. But the machine will not let me install any different drivers. I could be wrong about the driver. When it rains it pours, I also can not save any thing to word .When I go to start programs I can not longer see office in the panel. Are the two connected in some way? Any one who can offer a little sanity? Thanks
