    I am only able to go back three weeks. It looks like I missed my chance to find a restore point from a few months ago.

    You could try a repair installation before you go to a full reinstall:

    Repair Install Windows 8

    It's not supposed to remove data, applications or apps from the Windows Store, but I would probably take the opportunity to back up all your data first anyway.

    I'm having a similar issue. Had my pc about 3 weeks and was running my LCD tv as the main screen and my dell monitor as my 2nd screen. If I changed the source or turned my tv off it would flick over to my monitor. My PC ran an update over the weekend and noticed an AMD Driver warning message. The PC then stopped running duel screen and not playing through my TV. I managed to do a restore and the PC started playing though my TV again but my Dell monitor was just black. When I check my hardward in the control panel there is a yellow warning symbol. I run trouble shooter but it can not find the problem. The symbol for my dell monitor is flashing in and out. In the device manager screen everything was flashing in and out. I managed to uninstall my display driver and reinstall it but same issue. I then noticed the my AMD Catalyst Centre App had vanished. Managed to reinstall that and when I tried to detect my screens both screens just went black and flash in then black again for about 20 mins or so. I managed to turn my pc on and again my TV had stopped working. I have managed to get it working again but my dell monitor is still black. I tried using my Samsung 22in TV as my 2nd screen though the monitor cable and I have duel screen. I noticed this morning that I have no sound through my TV from my PV that runs through a HDMI lead. I didn't have a chance to check the sound settings but I do have sound though my stereo that is connected via a phono jack. Really have no idea what has happened to it other than an update ran. Really did not take any effort setting up duel screens when I got my pc and did not even have to use the AMD Catalyst Centre.

New laptop screen stopped working
Hi, I recently bought a Samsung ATIV Book 8, and the screen just stopped working. HDMI out works fine. How can I fix this? I have read to remove my battery, but I cannot do that on my laptop. Should I reinstall my graphics card driver? I wasn't sure exactly what forum this belonged in, thanks!

WIN 8 Screen saver not working.
This was not an upgraded system but brand new. Like the others my screen saver won't kick in. Can't figure out what might be the problem. It did work initially but after install my programs, it stopped. Not sure how to figure out what my problem might be. Thanks in advance
