Old Computer

My pc is so old it cant run my games ive had it for 7 years and it wasn't even good to start off with, but then i went into pc gaming and only played flash games and really easy to run indie games ive never played any good pc games other than maybe playing cod on a console. ive never expirienmce the quality since if i did want to run a game id have to run it on low and i would still crash nonstop.
