Hello all, i am having big problem with my vaio ar61m. after win7 instal windows cannot detect camera at all, usb ports not recognised. when i plug the phone it charges, external hard drive lights up but it doesn't open... All these issues come the same vista or windows 7. i was searching online for solution but couldn't find or these dont worked for me. Can some one write me a complete walk through how to instal everything after clean vista/win7 instalation so i will get fully functional laptop many thanks
