Every computer I have has some type of problem or another, its so fucking frustrating

Just added ram so now I have 4GB instead of 2GB, ran disk cleanup and disk fragment. reset the computer and it WONT START!!
Its been running this restore thing for the last 10 minutes with nothing but a scrolling blue bar, then pops up and says "Startup Repair cannot repair this computer" WTF?!?!?
I was using windows backup to another drive but I cant even get to that drive. I'm so fucking pissed, I hate this shit. My Macbook Pro never has problems, Ive had two of them now for almost 6 years and the only thing was a battery that went dead.
FUUUUUUUUUUUUUUUCK
