Are you able to start the PC up in Safe Mode?

i dont want to hear it right now when my uber computer took a crap and im paying for it when i have to be on my family computer thats so slow that a snail seems to be a race car

Where do you work?

call GeekSquad, clearly you tried to tamper with something you knew nothing about, which is rule #1.. dont touch it if you don't know what it does. Maybe you completely fucked your brand (<-- lawl) new computer and you will learn a valuable lesson.

Are you able to start the PC up in Safe Mode?

To add on to this. Is it restarting or just turning black but staying on?

Did magic blue smoke emanate from it?

its staying on but a black screen im jus going to try to reinstall it
