My mum went on holiday but left the pc plugged in the wall switched on at mains. the switch was on on the power supply.
When i try to switch the pc on there is
no lights APART FROM ONE LIGHT ON MOTHERBOARD .
no sound from pc speaker
no movement on fans or hard disks.
i have tried a new power supply but no luck
can anyone advise me on what to try next i know that it's either the mother board or cpu
