Hi Mike, typically that type of random instability is caused by a buggy video driver, most likely your video driver was updated right before the crashes started happening. Your best bet is to see if you can roll back to an earlier version of the driver until some future update fixes the bug in the current one.

MoI doesn't install files all over your hard drive so there isn't really any type of "more thorough" uninstall to do, the only thing you could do in addition to an uninstall would be to delete your moi.ini file (found under %AppData%\Moi\moi.ini , make a backup before deleting it) so it will get recreated with all default values.

You might also check in your %temp% folder to see if there are any crash reports there, they would be files named moi_report1.zip, moi_report2.zip - MoI will write crash dumps there if it's unable to write to the program folder.
