I have a system where either IE 8 or Firefox 3.5 will crash out without any error message, and do this spontaneously after about 1 or 2 minutes of being open. Chrome, however, is stable and doesn't experience any of these problems.

What could be causing these browsers to exit, and without any determinable error message? Is there something that links them together that is absent in Chrome?

Have you looked what windows application error log tells? Is there anything about these crashes written there? – Diskilla Oct 6 '10 at 13:44
Bad plugin? maybe the latest flash? – Am. Oct 6 '10 at 13:52
I reset IE to defaults, removed all plugins. Same behavior. Nothing in application log at all. – MattUebel Oct 6 '10 at 13:53
For which site or combination of sites does the crash occur? Do the browsers also crash when they're showing different sites, or just a blank page? Maybe it's not the browser but where you're surfing? – Olfan Oct 6 '10 at 14:44
Sounds strange...I would suspect Malware if the browsers are closing and no error messages are being recorded. Have you run scans to help eliminate the possibility of Malware? – CHarmon Oct 6 '10 at 15:06
