Well guys.....long story,

First all the specs:

Asus p5k Premium
Intel E6850
Corsair xms2-8500 4096mb Dominator at 5-5-5-15 running at 1066mhz.
Seagate barracuda 250gb 7200rpm
Msi 8800gt 512mb OC edition.
All Zallman cooled

The parts purchased at November 2007 exept for graphics card (no money then :P)
System was stable not oc'ed yet, needed new graphics card and HD's.
Then i bought the MSI 8800gt and installed it with the latest WQL nvidia driver.(Januari 2008)
Last 3 weeks i get sporadic blue-screen, first once a week, until today it was constantly crashing.

-Tried different Graphic card drivers, nothing helped.
-Tried running memtest, crashed over and over again.
-Tried starting up with 1 ram module, then 2, then 3 and finally found "a"problem.

At this moment my system is stable with 3 ram modules, as soon if i put the last one in (broken one): not starting up, or damaging nvidia driver, or after loading windows blue screen.

Three things stay unclear to me:

- How could a broken ram module affect my gpu drivers?
- How can 1 ram module break from a matched pair, normally both would break?
- How can my 3month old ram break, it even has an cooler from Corsair en never oc'ed them???
They give 10years warranty on this set.

Sorry for the long story guys...
Do you have any clue??

thanks guys and goodnight

Danny
