This one has us power users beat. Need someone who KNOWS this. My son gave his Mum a home built Games PC which worked fine for him, always under XP. It has started a weird mode. When powered down it will not retart unless the mains is switched off for a decent period, it varies but probably 20-30 minutes minimum.
If the mains is then switched back on it will start on the button, but not before.
Anyone know what causes this sort of behaviour. It otherwsie has a few odd problems but works OK. BTW on shutdown it seems unable to stop hpqste08.exe and DeviceIO.exe, not always but most times.
