Each time that you access files on a disk, the monitor blinks or goes blank for several seconds. What might be the source of the problem and possible solution?

There is an IRQ conflict, and you need to use Device Manager to resolve the problem.

Explanation:

IRQ is a synonym for "interrupt request line" and are lines which devices use to send interrupt signal to the microprocessor of a device. IRQ conflicts usually occur when a new device is added to a PC, and this can be resolved by setting the IRQ number and you can go about this by going using the Device Manager to resolve this.
