Well, I know that 64 bit operating systems can use up to 8 gb of memory so I didn't expect it to show up all 9 gb... and I upgraded to windows 8 from Xp like a week ago and in Xp it was showing up all 9gb so it's very unlikely for one of the ram sticks to be broken (although it's not impossible). And I will tell you more clearly what dxdiag shows me to make things more clear:
When I go to the system tab it says Memory: 6144MB, and when I go to the display tab it says Approx. Total Memory: 3303MB, so knowing that this added up gives me 9gb I'm guessing my video card is somehow interfering with my ram.. in the system tab it also says Page file: 3127MB used, 9151MB available so there is something mentioned about 9gb although I don't know what the page file is... can you draw any more conclusions from that? Sorry for the previous post, I didn't want to be aggressive or anything
