So basically I often get blue screen of death and I have much worse performance than I had few weeks ago.
So few weeks ago I couldn't log in into my user account on windows because of error "Could not load user profile". After that I restored PC with option to keep user data. Now I have poor performance in games.
Also during Windows set up my PC fell on the floor ( I have forgot that I have headphones plugged in).
After few windows updates it seems that blue screen of death disappeared. What could be the problem? Also I've downloaded new AMD drivers.

You dropped your computer, sounds like physical damage to the harddrive.
Run some tests on it to see if there are issues with it.

Just added few zeros to virtual memory

You're gonna have to be like a million times more specific and clear about the issues here if you want us to be able to successfully assist you. Right now all I understand is that
- you used to get BSoDs but Windows Update solved that
- you get poor video performance
- you once dropped your computer
If you notice that's really not a whole lot information and there could be limitless possibilities as to why you get poor performance. If you could answer a few questions I'll try my best to see what I can do and I'm sure others will also be able to help you.

1. Desktop or laptop?
2. OS?
3. Specs? (download speccy and screenshot it)
4. What framerates did you used to get in certain games and what do you get now? Try using more popular games because it'll be easier to tell how bad your computer is performing versus how well it should.

atom0s is right that if your computer did get damaged by the fall the most likely component that would get damaged is the hard drive, which could totally account for the BSoDs. However depending on how far it fell it could totally be fine.

Increasing the size of your pagefile will do absolutely nothing to speed up your computer unless you're already hitting the limit of your RAM + pagefile which to me sounds incredibly unlikely unless you have a tiny amount of RAM (again why we need to know your specs). And regardless of whether that's happening, you shouldn't be adding a "few zeros" to it, that's way too much.
