ya I'm not a computer expert but defiantly a computer geek cause of by brother being a computer programmer and shit and i hang out at the local computer geeks store i can normally trouble shoot problems

and if your having problems with games like video or performance
it's normally one of 4 things
Video card processor or overheating ( my current problem)
ram not compatible or bad
processor issues
or your video card slot on motherboard or possibly some else on motherboard is bad

comps are really like cars in every sense of the word they have many compents that must work in sync if one goes bad you got problems
