My computer is a Gateway tablet PC running on Windows XP. I allow all automatic updates to the operating system and other software I trust. Somehow an incompatible/outdated driver got into the boot system and it will not allow windows to start. the computer just keeps rebooting and rebooting and cannot start windows. the error line is DRIVER_IRQL_NOT_LESS_OR_EQUAL Technical information:
STOP: 0x000000D1 (0x00000018, 0x00000002, 0x00000000, 0xF8131225D)
iastor.sys - Address F813125D base at F8122000, datestamp 422F3bcc
How can I remove, restore windows XP configuration to an earlier date, without reformatting the C rive?
