It might be Alt/PrtScn, bit I have tried it a number of times. If I open a photoshop new picture and attempt to paste the clipboard contents to it, the paste option never becomes available, and if I attempt to copy it to a word document, I get a textual representation, not a actual screen capture. I am using no auxillary software.
Can I ask where you got the driver from? I have a HP D5000T and I think the onboard sound is SB X-Fi, I have been unable to get find a driver that will work?
Thanks
