Screen displaying unusual effects

My problem comes in two parts.

First of all, my screen started to display the oddest Visual effects. Whenever there is a black pixel on the screen, it turns red. Whenever there is a white pixel, it turns cyan. Indeed, at the moment, I'll have to type on a Web page entirely cyan. However, if I show someone a screencapture, nothing particularly untoward appears - they get a regular image to a blank Web page, but the resolution is reduced slot capacity of my laptop.

Which brings me to my second problem.

My screen seems to be perpetually in 1024 x 768 and seems to only go to this resolution. In addition, I can't adjust parameters of the screen (brightness, contrast etc.) so, as standard, I checked my driver files to find that my integrated graphics Intel has been replaced by a VGA Compatible video controller. Yet, seems to be an easy fix. I try to reinstall my integrated graphics driver to find the following message is displayed:

Setup failed to install one or more device drivers.

Setup will close.

No code/dump/error log was found of that. So I tried to delete this video controller VGA Compatible and then repeat the process. This time, the same error message that past, as well as a second in my device manager, that was something in the sense of:

Windows found driver software but has encountered an error.

Access is denied.

Well, wait a minute. I am an administrator, I execute the program elevated, and yet I'm still not access?

Summary:
The screen displays atypical errors

Impossible to install devices even on a social rank higher due to access denied
