Can't boot up friend's PC - was working fine until a week ago, now won't boot.
The PC is home built about 2 years ago. The motherboard is a Gigabyte GA-EX58-UD4P with an Intel I7 processor (1366). There are 6 sticks of ram each 6Gb - although the m-board manual shows 24Gb max. I have removed and tried various combinations of ram with no success.
On trying to power up, three of the fans move briefly but do not spin. Also there are 2 lights on the m-board which indicate the state of the DDR memory - one is yellow and the other is green. Accoirding to the manual the normal state should be off.
The m-board lights can only be turned off either by holding the power on button down for several seconds or by switching off the power switch on the rear of the case.
