Help: 3-year old multivision desktop pooter: 1. Turn on. Drive light at front winks erratically - no boot; screen stays dead. 2. Reset switch does nothing. 3. Turn off at back - back on. Symptoms repeat. 4. Turn off for longer - back on. Unlike before - computer is dead. Networking LEDs at back are still working. 5. After 1/2 hour and whilst pondering problem without any button pushing, the drive light at front shudders to life - back to winky blue light but no boot activity at all. It's just maddeningly unhelpful. Any ideas from the assorted wiggly amp wisdom of Arrse?
