I have Windows 7 64-bit Professional running on Intel Core 2 Duo, 4 GB RAM and nVidia 1 GB graphics card. The Task Manager shows only 3 GB of RAM, so I am assuming 1 GB is used by the graphics card. After I use the system for about 30 minutes, all of the memory gets used up and the system is responding very slowly. When I check the Task Manager, the CPU usage is low, but the memory is above 95%.

I cannot identify the process which takes up memory. But this started happening after an update installed service pack 1.

What might be the problem?

Are you sure the memory isn't just used for caching? – Mr Alpha Apr 5 '11 at 15:57
it can be a memory leak problem try to close your window gadgets for some time to see if it is a problem with any gadget. And if the problem solves this way then run your gadget one by one after some time. – kaykay Apr 5 '11 at 16:09

Use Resource Monitor (memory tab) to see if you can find the process or program using all the memory

All Programs > Accessories > System Tools > Resource Monitor

or a run command
