hi, just had some extra RAM to beef up my system but when I put it in the PC will not boot, checked it is in correctly and all I get is a long beep followed by a short one, then a short one every minute or so..
I have removed my old RAM and just left the new RAM in and still the same, so I'm guessing something is wrong..lol..
the new ram is :

many thanks
