okay. So this is the situation:

There are three slots for RAM. I have 2 brand new 512 DDR 3200 sticks. When I place just one of them in and put it in the top slot, the computer loads and boots just fine, but when I try to put RAM in either of the other 2 slots in any way (slots 1,2 or 1,3 or just 2 or just 3), the computer gives me this system corrupt crap.

What on earth is the matter?! Please, somebody give me a clue here...

Both sticks are good, because when I place either of them in the top slot, the pc boots fine. I ran the latest symantec virus scan on the whole system and it says everything is clear.

EDIT : Also, when RAM in placed in the 2 or 3 slots, the monito often flashes signal missing and shows nothing.
