As for mem test, last version 3.5 (or 2.5..nevermind ) just crush pc (restart) when i run it with all 4 dimms.
I discover new fact about my problem. PC wont start after "long" time being turned off, if you turn off/on lets say every 5 min it will always start. Which leads me to believe that it has something to do with power (and 4dimms and diff.memory type :) )
Now i left 3 dimms (2 old in dual ch. and 1 new) and turn off in bios "power on on 2 clicks" so it dont spend power (wireless mouse and keyboard receiver) on anything when its in turn off state.
If problem still be there i will go for 2 100% identical dimms with 2GB each.
Thanks everyone for help.
