Thanks for all your replies guys
Right, a few questions as I am a n00b to computing:
What does flash the BIOS mean, and how do I do it?
I think the chip for SLi is in the right way, I didn't rrmove it when I got the moptherboard, but I will take a picture for you guys to see if it's right.
The molex and 12V rail is another one I don't know. My friend helped me build it and well I'll take a pic of my whole setup inside.
Any guides on the above would be great
The computer is working lightening fast by the way, and so I think the CPU is fine, but I shall double check. I think it's just the GPU, I'll be back in 5 minutes with pictures
