Running Vista, 2gb of Ram (desktop system). This same irritating problem sometimes happened on my ex dell laptop (vista , 2gb ram). I have a number of windows open right now. At the moment using 970mb of Ram and 1870mb (out of 4312mb) page file usage .

But I cant open any more windows, like i have run out of ram and page file. RIght now, if I open another internet explorer window, it pops up and disappears (like when there is no ram). If I close Yahoo messenger (for eg) now I have enough memory to open a new internet explorer window.

I have not touched the page file or anything, so why does this happen, its so damn irritating. Any ideas??? thanks
