No problem at all. I just hope it is fixed. If you have another BSOD because of ram, you will need to run each stick in each Dimm Slot. That will tell you if you have a bad stick of ram or whether you have a bad Dimm slot on the board, which does, in fact, happen. What you will typically see is a ram stick which will pass in Dimm slots 1,2 and 4 but will fail in Dimm Slot 3. And you were correct in that it is possible for all the ram to pass the test, but there may be 2 sticks that just will not work together. That is why you will often see people advocate only running ram that comes in kits. That is because kits are tested so that all the sticks rub well together.
