I to also own a SP4, Having identical issues Plus More, Video TDR Driver bluescreens, Video memory managment bluescreens, ive done all the windows updates, i downloaded the windows SP4 driver package from there site, ive also then done a factory reset and done the same again, STILL THE SAME ISSUES
The device is flawed in so many ways i am unable to do anything from basic word processing to any form of adobe work
Im out of the 30day period but a return is a must for me now, Do you think its still possible?
[edit] Another spontaneous issues, when under 80-95% CPU Load the device cannot maintain a connection to Bluetooth or wifi devices? Even when plugged in running on mains power? Wtf?
