I have a Lenovo g570 laptop. After an auto-update got the IRQ less equal message, the computer won't start. It shows a black screen and a blinking cursor in the left corner. The F2 key won't work. How do I fix this?

    What sort of update you went through? Did you update the BIOS? Make sure you don't have a usb device plugged in or a DVD disc inside your laptop's drive.
