I'm trying to build my own PC. I bought the bits as a package from Scan.co.uk, so I assume they are "matched".
M/B: Gigabyte GA-Z68X-UD3-B3
CPU: Intel Core i5-2500K 3.3GHz
RAM: 8GByte Corsair Vengeance DDR3 (2 x 4G DIMMs)
PSU: Cooler Master GX 80+ 650W
When I press the power switch the case fans and PSU fan spin for a split second, then stop. The unit does not boot. There are no beeps.
I've disconnected the Hard Drive, DVD and video card with the same result.
I've checked the cables and they all look OK. I also checked for anything "dangling" over contacts that might cause a short, but there's nothing obvious. Nothing is obstructing the CPU fan.
I installed the two RAM modules in what I believe is Channel A (initially I plan to operate in single channel mode...with 8G of RAM). So they are in slots labelled DDR3_4 and DDR3-2. reading the motherboard manual it looks like I could install them in any two slots and they'd work (maybe not to max performance, but they should function).
One other thing I noticed is that the Cooler Master case was supplied with all brass spacer screws, rather than a mixture of brass and plastic.
Any advice welcomed!
