Every time I go my folk's place, I always check their PC to make sure the latest updates have been applied. Lat time I was there, I finally set the preferences to download and install patches automatically, so I sleep much better at night. If you are your relatives' IT dept, you should think about doing the same.
Anyway, my machine started randomly rebooting this weekend. I checked - no virus. Hmm. Well, for once, I'll submit the error report to our servers in Redmond. Holy $&%* - there was useful information there! The system figured out it was *probably* a bad memory stick (I was leaning that way anyway), and the really cool part - it recommended I download a little memory testing app that nailed it.
This was actually good timing - I'm getting things set up for the arrival of my new child - a Canon 300D. I took the opportunity while performing open heart surgery to add 1GB new memory and another 120GB drive. My, how zippy 1GB of memory makes XP!
