Hi,
Thanks for your help, here is some info for you;
This problem has been discovered while initially investigating why my PC was occasionally shutting down on its own. The PC would be left for some time and when I’d come back the PC was off. This is a new PC which I put together myself, there didn’t seem a specific time when this ‘shutting down’ problem began. After asking on other forums some people speculated that the problem may be connected with the PC going to sleep (I was having another issue whereby the PC would go to sleep by I was never able to ‘wake’ it).
