z..sus type was the setting I was talking about. I think u need to get into the windows and have a look device manager for a start. For BIOS settings, I usually disable a lot of things that have given me issues before. For example, on-board audo, bluetooth, firewire. I'd start working ur way through the hardware and see what u can turn off and see if that makes a difference. I know its not useful info but only thing I can think of...anyone else got better advice?
