The video image is intermittently fluctuating or disappearing from view

Explanation: The screen image is disappearing or intermittently fluctuating, either completely or partially.

Diagnosis: Having the picture partially disappear on an intermittent basis normally implies some sort of electrical problem. The cable is usually the culprit.

Recommendation:

• Check the cable connections carefully, and make sure that it is straight, not kinked, and that it is making good contact with all the pins at the video card end and the monitor end as well. Try replacing the cable if possible.
• Make sure that the video card is not loose in its slot (unlikely that the PC would work if this were the case at any rate).
• There may be a problem with the monitor itself. You should consider taking it to a repair shop to have it examined.
