iv just installed one of them,and everythings working fine,but when i install the second one,the computer doesnt start.it goes onto a screen and says how do you want to start your computer
safe mode with networking
start computer normally
and i click on start normally and then it goes to a blank screen,and nothing happens,then i take the second set of memory out and turn the pc back on and it works again.
Does anyone know what i might be doing wrong.
