Hi folks. I thought I posted this yesterday but it hasn't appeared to here we go again, hoping it's not a double post! My system has been running for years with very few problems ...... until this week. Last few days it has been doing spontaneous restarts once or twice a day, usually at the most inopportune moments!! No error messages, just restarts. In my Startup and Recovery settings I have all three boxes checked, viz:- 1) "Write an event to the system log" 2) "Send an administrive alert" 3) "Automatically reboot" My questions are:- 1) Where do I find the 'system log'? I've spent a long time searching to no avail! 2) What is an 'administrive alert" and do I need to uncheck 'Automatically Reboot' in order to get one? Any advice will be much appreciated. Regards Stuart

If you uncheck 'Automatically Reboot', an error message will be displayed rather than rebooting. That error message will give you a clue as to what's causing the problem. One common cause to randowm reboots is an overheating CPU. Have you checked the temp? When's the last time you blew the dust out of the case, especially the heatsinks & fans. And just FYI, do NOT use a vacuum on electronic components.

Thanks for reply jam. OK, I will unset autoreboot and see if any clues present themselves. BTW yes. I have been down the overheat road but no problem there. Regards Stuart

I was beginning to think that simply by posting here I had frightened my machine into behaving itself ..... but No. Whilst flying online with MSFS2004 last night, my conversations with Vancouver ATC were rudely interrupted by the BSOD!!

Things like that are really hard to tell from over a forum. It can be a number of things, a failing components (everything fails eventually) and bad driver update or a bad Windows update. You'll probably have to have a professional come look at it. If your feeling really adventurous, though, you may want to download Microsoft's debugging tools which includes a memory dump reader to read the dump file and look for clues in there. http://www.microsoft.com/whdc/devto...
