nope i have AVG,
Not sure what ur question is on how old my computer is tho but i just bought my motherboard,CPU, and RAM 2 months ago. My video card is pretty old tho.
Also, could over clocking be a problem? because i remember my brother overclocked it once and it started to restart the computer when im playing a game or make my game all fuzzy and boxed pixel and then restart my comp. Then my brother brought it down alittle i think and it stopped all that.
But i cant reach him right now, he wont be back in 2 months, so could over clocking be a problem?
