hi, thanks for the input guys but been very busy and havnt got round to even visiting this forum for a while. It deff wasnt cpu, deff wasnt any other component as all run fine in a variety of mobos I have at home. Should have said that b4, but I guess I knew it was a mobo prob. The people I bought off where reluctant to take it back, blaming me for incompetence or a faulty cpu HA, I have grown tired of people assuming I know as much as the average Jo. Anyway I eventually got a no quibble RMA and sent it back today telling them to test the board with a 133 cpu as the static I've had off there tech dept has been terrible. B4 they wanted to test the cpu(s) as well, and I didnt even buy any of my cpu's off them. B***ards. They even insisted on walking me thru bios settings when I had set to fail safe defaults and arrrr well the list goes on. I wont be buying even a fan off em again. Too much attitude off tech guys.
