Should you use it up within a certain range of buying it? Because my paste dried up/disappeared and I believe that was what was causing my blue screen problems I posted about earlier. This AS5 is at least two and a half years old if not older, and peeling the sticker off the tube revealed a not-so-continuous color; i.e. parts of it were less "silver" and more "yellowish-grey."
Should I buy a new tube?
