When restart occurs, I get the following msg - "Boot and select proper boot device. Insert boot media in selected boot device and press a key. Nothing, but same msg. Power down and +15 minute wait, will restart as normal. Everything had been working fine. Sometimes when I view a movie using Nero, same thing happens; Media Player ditto. Would appreciate any advice.1 person needs an answerI do too

Your power supply may be failing or it may be your hard drive. You can test the hardware yourself or take the computer to a reputable local professional. Don't use a BigComputerStore/GeekSquad type of place.http://www.elephantboycomputers.com/page2.html#Hardware_TshootMS-MVP - Elephant Boy Computers - Don't Panic!
