ReBoot and selected proper boot device

[Adam5150]

Hi All,
My computer turns on as normal and runs for 10, 20 30mins or if I am lucky an hour, but then I get this message pop up - Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key.
From reading other entries it seems this is happening to other computers at turn on stage yet I can turn mine on and work on it or play music but it eventually goes to the black screen after say 10 - 30 minutes.
Any help for this no computer knowledge bloke would be great.

Hi there Adam5150,

My suggestion would be to back up the data stored on the drive.
After that, you can test the drive with some of these: http://www.tomshardware.co.uk/forum/282651-32-best-diagnostic-testing-utility

See if there is something wrong with the SMART values.

Another thing you can do is to attach the drive with different cables(SATA and power ones) to another SATA port.
