Problem after successful installation of fedora 22

Dear sir, I installed fedora 22 workstation using .iso through bootable usb. Everything was done prefectly but when I used a doc for writing a letter, the whole screen went hazy (multicoloured bars). I am using fedora first time and made bootable usb stick for the first time ( and I really have grown interest in it). I dont know what went wrong? Hope you could help!!! Also, my usb stick is no longer recognized by the system!

Which doc application you’re using for writing? have you tried LibreOffice or OpenOffice?

Libreoffice I used. I am also facing same issue not only in libreoffice but also in general

Also sir I want to install hp laser jet pro p1108 printer
in fedora 14 and because of this I loaded fedora 22.
