Okay, a few minutes ago I noticed my comptuer was running really slowly, so I went into activity moniter (it took about 10 bounces to open) and it says I have 8mb of free ram. I have 768mb in the machine, and all I had open was iTunes, Safari, Limewire and Activity moniter. Safari was taking up over 100mb of ram, so I decided to quit that, and see what happends. THE FREE RAM STAYED THE SAME!!!!! It went up to 80mb for a second, and then it went right back to 8.64mb free or sumthin like that. I restarted the computer.... 550mb free ram! *whew*. I open up itunes, and safari and limewire... things start to bog down..... all of a sudden theres 757mb of INACTIVE ram in the activity moniter, and i'm back to 8mb free. I just shut down the computer completely, and started it up again, zapped the P-ram, and i'm watching what activity moniter does every time I do something, and it seems that every time I open an application it adds a HUGE amount of ram to "Inactive" and never gives it back. For instance, when I opened iTunes "Inactive Ram" went from 90mb to 132mb, and when I quit iTunes, it's not gonna go back to 90mb. Is a virus eating up my ram? Or do I have bad ram?
