I bought the computer from my tattoo artist and got a fair deal on it. Its brand new and everything is fine but the finger print scanner wont work and sometimes a window pops up about not having a genuine copy of windows, it also came with the start up disks but I cant figure out how to restore it to just the way it should be when you buy it. Long story short im not extremely tech savvy and I would like to just revamp the computer. Get the correct software installed, copy of windows, the whole nine yards. How would I go about doing that so in my case I would have the perfect computer? Its going to be used mostly for games and music. Have 500 gb also.
