Was listening to some mp3's on my computer yesterday evening and after leaving the computer for a couple of hours on my return I found it had frozen. Couldn't do a soft reboot so had to hit the reboot button.
After this the computer did not seem to recognise the IDE drives and does not show them in the hardware menu when booting. This has happened once before and after leaving the computer off for a couple of days it seemed to sort itself out.
As far as I'm aware I have no viruses on either drive - and haven't been connected to the internet on it for over 2 months to contract a new one. I have checked in the BIOS settings and it HDD Detection it knows the hard disks are there but I cannot select either of them as a boot device.

Bearing in mind I'm a complete novice when it comes to computers - does anyone have any ideas?
Cheers.
