Updated driver after 8.1 update

Ok, where to begin.

First, windows 8.1 update has caused me nothing but problems. Ive already had to restore to factory settings thrice because of it and lost most of my files. The update causes my screen to become as dim as settings will allow, and i cant adjust it, ive tried many solutions. Recently, my computer has forced me to update to 8.1, there was no option to not update. Again, i had to restore my computer. It took me a week to get some of my files back. Then AGAIN it forced the update on me. I say, screw it, and bought a new monitor, Devices not connected to my laptop are controllable. I then try to run a couple of applications, and they are slow to start. Finally they start and then monitor starts flashing rapidly. I look and see how to fix this problem and found many references to updating drivers. I do this, but all my drivers were up to date. This is where the unsolvable problem comes in for me, i find a few references to restore drivers to a previous model, i do so. Then after five minutes, my computer restarts. After it finishes, it begins to reboot. It gets past the samsung loading screen, then the monitor goes black. Its still on, i can move my cursor around a bit, bht it wont do anything beyond that.

Please help
