Win7 Graphics (?) Problem
I have Win7 64-bit on a Lenovo U510 laptop. This system has a combination of Intel HD 4000 and nVidia GT 625M graphics that I don't understand very well. Everything was fine for the year or so I've owned it until recently, when it started exhibiting a strange combination of symptoms .....
- Messages "Do you want to change the color scheme to improve performance?"
- Copy and paste isn't working. When I copy, either there is no paste option at the destination, and/or it pastes what seems to be a current screen shot.
-Slow graphics performance - when I try to move Windows around on the screen, there's delays, hesitation, jerky movement ...
I ran MalwareBytes and found and removed the PUP.Optional.Softonic malware. Other virus scans have been clean. I cannot see any high-CPU use processes in the performance monitor, or spot any other problems. I reinstalled both the Intel and nVidia graphics drivers, no joy. I've never encountered anything like this before, but I suppose my best guess is a virus or a hardware problem. Recommendations to diagnose and/or fix appreciated.
