When starting up, my computer reboots itself at the Windows Log-In page. After disabling the automatic reboot option, I get the "blue screen of death" stop error screen with a note saying "DRIVER_IRQL_NOT_LESS_OR_EQUAL".
The last thing I did before this started happening, which was yesterday, was update my java program (JAVA 6 Update 3) and also set-up a new Belkin N1 wireless router. I've tried System Restore to a checkpoint previous of these actions, but to no avail.
Please help
