my pagefile.sys is missing, there si no pagefile on the C drive, not a hidden file, regedit will not hold a pagefile setting, manually set the pagefile don't hold in the advance tab. would reloading window 7 correct this problem.
Are you basing this on looking at the drive itself?
What are the pagefile settings for the system:
Start -> Right-Click "Computer" -> Properties
Click "Advanced System Settings"
Click "Advanced" tab
In the "Performance" section, click the "Settings..." button.
In the "Performance Options" dialogue, click the "Advanced" tab
In the Virtual Memory section, click the "Change..." button.
If the pagefile is really completely disabled, it should look something like this:
To set up a pagefile, click one of the disk names to select it, then click "System Managed Size" or click "Custom Size" and enter the minimum and maximum sizes.
Important note: You must click the "Set" button! If you just click OK the settings will not be applied. This has tripped me up several times.
i have tried system Managed size and set buttom, check the regedit and manual set pagefile (pagingfile.sys 4096 4096) an i restart the computer the allocation is back at 0. i have check the administrator permission for the machine.
