Thanks for the replies.
I haven't yet tried a speaker (indeed the kind that plugs onto the mobo
) - I'm quite surprised the new Mobo didn't come with one to be honest, and sadly I don't have any spares. Maplin.co.uk want £4.99 for one!!
I'm going to try a VGA cable this evening and will report back how that goes. Failing that I'll see if i can get windows installed with the onboard graphics when my DVD drive turns up, then I can put the GFx card in and try again.
Tried the keyboard in different USB ports but it still just came up blank.
I suppose at least I've got to the bios using onboard graphics so the motherboard and cpu are working just fine. i3-2100t was showing 37 degrees which is hopefully about right.
