Limited OS Functioning After Checkdisk

I wanted to delete a folder in my documents but it was giving me an error which I cannot remember exactly now, but after doing some research, most sites had suggested that I run a Chkdsk. My computer successfully completed the Chkdsk, but now my computer is in some sort of coma where it loads up fine, but after logging in, there is no text whatsoever on the screen. On top of this the start bar does not work and any explorer based functions are extremely large, pixelated and absent text.
