Hi all, system spec currently is:

150GB HDD
560 TI geforce OC'd
GIGABYTE MOBO udp4 something only supports DDR2
4GB DDR2 corsair
4.2GHZ oc'd 965 phenom
corsair h60 cooler
----------------------------------------------------------

I'm getting lots of blue screens even though i just reinstalled windows 7, some of them include:

"system service exception"
"page fault at nonpage area"
"irql not less equal"

as well as a few others.

I'm thinking that its the memory or mobo is getting old or something i dont know.

my problem is that I have been wanting to upgrade MOBO and RAM to a mobo which supports DDR3 and dont know if new MOBO and RAM will fix my problems.

I ran memtests before and came out fine. I dunno what to do regarding the blue screens, as well as what to upgrade
