I have an AMD64 machine with 4GB of RAM that has recently had Windows 7 installed on it.

The hard drive is now being accessed 1/sec--rhythmically. It appears to me that it is paging constantly.

However memory diagnostics indicate only 20% of the RAM is being utilized.

I know how to change the size of the paging file, but without disabling it all together how can you set it to address more ram and do less paging?

if win 7 was recently installed its possible the frequent HDD access you are witnessing is just the indexer for the desktop search, especially if you have a good amount of pre-existing files carried over – Xantec Apr 20 '11 at 21:32
It's probably not paging activity you're seeing. Aside from the hard drive being busy every 1 second, what leads you to think it's a memory/paging issue? Does it only do this when idle? Does it do it in safe mode? – Ƭᴇcʜιᴇ007 Apr 20 '11 at 21:35
How did you determine it is accessing the page file? Win 7 is always accessing the hard drive compared to XP, and its not the page file. – Moab Apr 20 '11 at 21:37

Hard page faults are an indication of paging, not regular disk activity.

Open up Resource Monitor to see what processes are accessing the disk.
