I don't know if this is a windows problem or not.
I get the message "not enough memory or not enough memory on harddrive.
I EVEN get this message when I get up of a morning the computer not having been used during the night.
I've checked my hard drive, I have 21 gigs of free space. I have 384 megs of sdram. I even downloaded a program that tracks VIRTUAL memory usage during a session and you can PULL up the information as to what the peak usage was during the session.
Is there a way to check what programs are using how much memory?
I have a
Compaq 5000z 5umv11 computer
Athlon 1 gig processor
384 sdram
Maxtor 40 gig hard drive
Windows XP Home Editionhttp://reviews.cnet.com/5208-6142-0.html?forumID=7&threadID=42641&messageID=499859Thanks Merlin. That thread led me to bunches of other threads on the subject. I control+c, control+v'ed them and will try them tonight.Low disk space or low virtual memory?

There is a rather significant difference.How big is the drive and what PERCENTAGE does that 21 GB represent?

If you have a 200 Gb drive you would need 15% free-space to run defrag.

200 GB = 186.26 GB (Binary) and 15% = 27.94 GB

So if your drive is 200 GB you would be 6.94 GB short.

Any use...

"Run Disk Cleanup and remove all but the last restore point. See if your System Restore cache and Recycle Bin size is set at a reasonable level (Say 1024Mb) on each drive, and reduce the IE Temporary Internet Files cache and History cache to the minimum. Install CCLeaner and clean out all of the junk files. Unhide all files and folders and remove the hotfix uninstallers ( $NTUninstaller$ ) from the hidden C:\Windows folder and remove their entries from Add-Remove programs.
(Note: Some Security updates should NOT be removed so check in add-remove programs - before - doing this task.)
Then remove the contents of:

The C:\WINDOWS\Downloaded Installations folder
The C: WINDOWS\SoftwareDistribution\Download folder
The C:\WINDOWS\Temp folder
The C:\Windows\pchealth\helpctr\Datacoll folder, and...
The C:\Windows\Prefetch folder

(You can add these folders to EmpTemp if you have this program installed.) Then run chkdsk and defrag."
