Hello, I have a peculiar problem in my W7 Ultimate 64bit install.
Lately, once in a while memory usage goes up to 99-100%, and then it goes back down with no apparent reason.
The strange thing is, task manager will show normal memory usage, with the sum of all processes adding to a number far below 6Gb. And yes, it is configured to show processes from all users.
I initially thought that it was Firefox 4.0, because the first time this happened I closed Firefox and usage went back to normal almost instantly.
But then it happened again, and closing Firefox wasn't useful, still had to wait a few minutes for the situation to fix itself.
Is there a way to find out the cause of this?
