Problems after hard drive replacement?

Question

Iron

Previously, I asked a question about the fact that the computer was frozen with the preparation of automatic recovery. Took the laptop to the service, they said that the hard drive flew. Replaced, Windows-8 reinstalled (using the old key). Everything ended well. But the computer began to work a little incorrectly, namely: the screen became a little bit dimmer, the video plays a little worse, the cursor began to move not smoothly, but jerkily. The settings didn't help. I heard that you need to replace the drivers (by the way, when I looked at the device and printers section of the DEKSTOP device, there was a warning: there was no driver). What to do?

Answer 1

Install driver

Answer 2

On the website of the laptop manufacturer, look for your model by the full name and install the drivers.
If Windows 8 was included with the purchase, then there should be drivers for everything.

Answer 3

Install drivers.
The only strange thing is that in the service center where you took the laptop for repair, after reinstalling the operating system, you did not install the driver. Some hacky service center.
If you do not understand how to install drivers. Contact the same service center, claiming that they are hacks or install one of the programs that allows you to automatically update the system drivers. Of course, such an option, but the current one. DriverBuster or DriverPack.

Answer 4

To begin with, put a 10-ku.
And if something does not work out with the drivers (which is unlikely), think further.
