Hey. Right now Windows Task Manager says that I am using 50 per cent of my physical memory (1.51GB out of 3GB). Why? I only have Steam, Windows Live Messenger and McAfee running and everything else running I assume is OS-based. So why the big drain? I used to run my old pc with only 512MB of RAM and could have 3 aforementioned programs running and it was just about as fast as this. What's with the big memory drain? I had a game crash because it said there was no more memory available! This is unbelievable! What the hell is wrong with Vista! EDIT: I just restarted the pc and it was using up 1.51GB of RAM for a while and then it dropped down to 0.99/1.1GB around now. That's more like it. I have no idea why it was up that high. One third of my RAM being taken up is fine but not half. I don't mean that I've answered my own question though. I'd still appreciate some help and maybe an explanation of how I can improve my RAM usage.
