My N900 rebooted by itself this morning, and when I wanted to use it, the background was black, almost none of my programs wanna work, all my contacts and called and recieved numbers are gone. When I reboot it, it shows 'Internal error' atleast 3 or 4 times. It doesn't see any backups, so can't restore. MicroB dead, email dead, etc. Didn't install any programs for the last month or two. Was working fine this morning. Plugged it into laptop to see if I can use it as internet connection when it rebooted.

Please help.
Thanx
