Yes. Test each stick of your ram one at a time in the ram slot closest to the cpu. If the ram is bad, you'll get alot of errors almost immediately. Also, if your bluescreens have a ram address listed, then that's another indicator of ram problems. Handle the ram with care. Use an esd strap or at least keep your fingers off the chips as much as possible and touch the ends or top only. If you're mixing different ram sticks, then that would also cause potential problems.
