Recenly purchased Mesh+spbc (Pc Advisor recommended) AMD 64 300+. The computer crashed once prior to SP2 install and then altogether after that. On advice of Mesh Restored to Factory setting and therfore SP1. A couple of hours after restore the computer crashed again twice. After rebooting itself it came up with Microsoft error message which I sent, Unusually it came back with a fix for the a suposed problem with Pinnacle Instant cd/dvd ver8.0. which I downloaded. Pinnacle now doesn't work, although it didn't really work well before and looking back was probably the cause of first crash. The error message was Non page Fault, which I have heard others suggest is a memory problem. I have uninstalled Pinnacle instant and to date (touch wood) no further problems however am now a little concerned there may be further underlying problems. Any similar probs or advice for a somewhat newbie to home comupting!
