Hey up,
MrsTT's desktop (Dell, c.3yo) has packed up in a fit of bleeping. On switch on it bleeps twice - repeatedly. Nothing comes up on the screen - CPU fans spin up OK, HDD works fine (tested in an external drive enclosure)... My money is on either motherboard graphics - or some motherboard issue... IIRC normally for memory/cpu errors it'll fire up enough to give some message on screen...
Any other thoughts out there?
Going to dig out an old external graphics card to try next...
