The PC will crash when no-one is near it. When this happens it takes an age to power it back up. The power button seems to be disconnected. Then it will just power up no problem. This can be up to an hour later. There is not even an error report to send off.
The PC will crash whenever a graphics program closes down. This is not an "every time" problem, but 7 out of 10 times. I think this is something graphics card related as any media player or game can trigger a crash.
Does anybody have any ideas what could be causing these crashes?
Thank you for your time.
