I know absolutely jack really about computers,
this was kindly donated to me by a very good forum member,
my old PC was given to me by the SiL about 3 years ago after it kept blue screening on her, she had it about 5 years before that.
I like to build one every couple of years mainly over the Christmas break for something to do.
My son is doing Computer Science at Uni so we are continually messing with his machine, he has been lucky having all his stuff provided free by sponsors from the teams he has played for in the Call Of Duty scene.
