It is a Gigabyte mother board, and I cannot find the download at Gigabytes site either.
Mmmmm....Speedfan. Well, I have no love for this useless little program(personal opinion). It doesn't normally run long enough to test any thing.
I was having a chat to a mate of mine, and I reckon it is the mother board. He has a spare board and we're going to swap it out and test it. Thanks for all the advice, I will take it all on board before I pull it down.
