Me again. Sorry.
I was just playing a game and the system crashed. Horizontal lines across the screen, wouldn't respond to any inputs. I was forced to power off the system.
Now when I power it back on there is plenty of fan activity but not much else. No signal seems to get to the monitor and nowt happens.
In the case I can see two lights on the motherboard. A red power symbol and a green-lit reset button. I can't recall if they are usually on or not.
I've logged a support call but I wondered if anyone could suggest anything I could safely try to either get the system to start up or at least to give more useful info to the Scan support folks in the meantime? I'm never by the machine during working hours so anything I could do to speed up the diagnostic process would be good.
