By format your laptop I have to guess you meant "return to factory condition." Formatting a disc does not install the OS, drivers and required hardware apps.
So the problem is hardware if the factory reset fails. Determining the hardware can be hard as few companies install good diagnostics.
Be sure you unplugged all USB devices before you do much else.
Hi,i tried to solve the blue death screen (driver_irql_not_less_or_equal)by software but didnt worked out,so i want to know if there"s any way to solve the blue death screen by only touching,moving or changing the hardware? (by the way i have a laptop Dell Inspiron 3521 and i dont mind format my laptop)
