@Gwladys St. Glory @Dylan and @ other people that might build stuff.
I have a DRAM issue. I had 2 x 2gb sticks of Corsair 1333MHz and drunkely bought a 1 x 8gb stick to upgrade. As luck would have it, it is exactly the same model etc, so theoretically I can have 1 x 8gb & 1 x 2gb (I only have 2 slots on my MB).
Well apparently not. My pc hangs on the "Loading Windows" screen, I can't even get to the BIOS without taking the 8gb out and putting the 2gb back in.
I've updated my BIOS which I thought might do it (seeing as it was from 2011) but no joy. Any ideas? Oh yeah, I'm runnning a fresh (and updated) Windows 7 Ultimate 64bit.
RAM - Corsair XMS DDR 1333MHz
MB - ASUSTeK P8H61-M LE/USB3
