My sister's antique Asus P2 450 Mhz PC has recently been behaving erratically. Various faults can occur. One fault is
a continuous pulsing audio start up alarm and no sig on the GUI. I can clear it with a 'mains shutdown'. The other fault is where the computer is locked just before shutdown and keyboard lights flashing/no sig to GUI. It looks like the PC is at the point where the trip shutdown relay doesn't 'kick in so system left in limbo'. Has any member experienced similar probs such as these? My hunch is it could be a CPU/venting prob but not sure. The PC returns to normal function after mains shutdown so MB/CPU appear to function OK for a considerable period. Any useful advice welcome. Note the OS is WIN XP Pro.
