I suspect you have a jumper on ur mother board that is in the wrong position,, I think they call it safe mode,,, or there is another setting in your BIOS that needs changing.
If you are not too scared take a look at the latest BIOS for that board & upgrade if necessary.
Thanks, that seems to be the it doesn't it. I'll try it later on. None of the pictures of the board I could find were clear enough to see jumpers, and I don't think he can tell the difference between a jumper and a 2 pin plug of some sort.
