I have a Dell Latitude Laptop with Windows XP. I got it used, so it has no software that it came with. The dreaded Blue screen keeps popping up which has stated many different error names like BAD_POOL_HEADER or DRIVER_IRQL_NOT_LESS_OR_EQUAL. I can't start the computer or go into safe mode to fix it. I know it is a corrupted driver, but I have no clue how to fix it. Please help. Thanks for your time.
