Huge memory usage when burning cds, installing games

[Darklife]

I'm experiencing a rather strange problem. When I am installing a game from an image my memory usage goes up to almost 100% and stays there until I restart my computer. Similarly when I was burning a DVD DL disc it also neared 100% and later dropped down to around 70%.

I find this inexplicable, seeing as I have 4 gigs of RAM, and am running on Vista 64. I have resorted to manually counting the amount of RAM used up by the various processes, but it is nowhere near 50, let alone 90%. So can anyone explain to me what the hell is happening? It's very tiresome as my computer is practically inoperable when I want to burn a bloody DVD.

Hope this helps do a google search for vista 64 sp2 beta I'm running it and it seems to have helped alot.

Also you should check and see what processes are running I suspect you are running anti virus software usually norton gobbles up everything, if you have norton this may be an issue . I use avast and it works pretty well costs nothing and uses next to nothing in resources. If you have norton let us know. Dont just uninstall it or you are begging for more trouble. They have a uninstall tool that is used in safe mode to uninstall after uninstall.

If this isnt the issue I would suspect spyware, adware, mall ware, ect. Let us know hope this helps.

As of now I'm using NOD32 so I doubt there's a problem there. I guess I could sweep my system with Spybot, I'll let you know about the results.

EDIT: Nope all clean. I have no clue as to what could be causing this.

Vista uses memory like a cache. It doesn't unload anything until something else needs the memory. Under this model of memory usage 100% is where you want to be.

Alright, that sounds reasonable. However I have yet to understand as to why such an amount of memory is taken up by an emulator program( PowerISO in this case). I had no such experiences on my past XP pc, or is this a Vista "feature" ?
