HP Switchable Graphics Problem

My computer is an HP Pavilion dv6-6047cl Entertainment Notebook PC with Intel i7-2630QM 2.0 GHz processor, with 8 GB RAM.
I have had several different graphics problems and have upgraded the drivers.
It has HP Switchable Graphics with an Intel HD Graphics 3000 driver and AMD Radeon HD6700M, with the Catalyst Control Center (CCC).

The computer recently crashed and would only open in non-Aero mode (screen looked like safe mode).
It also made IE11 settings changes to the computer, and added a search add-on called "OneSourse, which I have deleted.
These problems were not corrected by system restore.
I scanned the Computer with Microsoft Safety Scanner, Microsoft Security Essentials and Malwarebytes, and it checked out clean.

Due to continuing graphics problems, I deleted AMD Radeon HD6700M and Catalyst Control Center, and am just using the Intel HD Graphics 3000 display driver.
It seems to work fine in this configuration, as there is no more CPU robbing Catalyst Control Center or freezing screens on start up, among the other problems I noted.
I normally use the computer in plugged in mode.

Is there any down side to eliminating the AMD Driver and CCC and using only the Intel HD Graphics 3000 display driver?

I do not use this computer to play games, and while it could possibly use it for Blu-ray playback, it is primarily used for Internet surfing, Youtube, and running Microsoft Office programs.

Hi, you deleted or uninstalled? Also you could have just stopped the catlyst control center from starting at start up. Have right clicked on the desktop, preferences and seen what theme it's using? Can you change it to areo?

I uninstalled the AMD Driver and Catalyst Control Center.
I am only presently running the Intel HD Graphics 3000 display driver.
In Device Manager, where "AMD Radeon HD6700M" would be listed, it now says "Video Controller (VGA Compatible)".

Seems you should reinstall it and then just stop catalyst from loading on startup.
