Since updating my HP Pavillion 64 bit to Windows 8.1, I have been unable to use an HDMI cable or reduce the computer brightness. I figured it would be a simple fix: restore to before the update, and wait for the bugs to be worked out. However, every time I attempt to access the control panel to perform a system restore, the entire OS freezes. Can someone help me resolve this?
Update: I tried to power on my computer just now to no avail. Stayed on the HP loading screen for 30 min.
