PC locking up (video?)
My PC has begun to play up.
When playing back videos it occasionally stops playing then gradually begins to lock up completely. Each time it does this a single error "Beep" occurs through the built in speaker.
Rebooting sometimes cures it but occasionally a second reboot is needed.
I initially suspected the PCI video card so this was removed and the built-in video output (which I'd not used before) was selected. It still does it.
Any clues?
