Hi I have supped up my 1737 with windows 7 64bit, quad Q9100, 2x 1TB drives, bd-rom drive, 3g module, wifi with built in bluetooth card, but webcam is NOT working?? It was but comes up in  device manager as "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)."

Any answers or solutions please??
