I'm at my wits end with my new build. Bought everything a couple of weeks ago and could never get the system to boot for more than 1 second. Sent everything back to Scan and they said the memory was faulty (which seemed quite unlikely). I received my goods back today with a new set of memory, put it all together and it still wont boot up! Can someone please help! My spec is: Asus P8z68-V GEN3 i5 2500k Corsair 8GB 1600MHz. Cooler Master 500w PSU Im using the standard heatsink and have no other components connected. If i press the on button the VGA button lights once and at the same time the CPU light comes on twice very quickly then turns off. If i hold down the power light the CPU light blinks 4 times but I'm not sure if this is related to the problem. I have checked the ATX CPU power is plugged in correctly and the heatsink is on tightly. Has anyone got any suggestions to try? Thanks in advance
