I keep getting message"low on Virtual Memory". I have reset VM to max. 576Mb but it has not helped. Rebooting solves problem but only for a few days. Most frustrating. Please help. Is it a hardweare or software problem

Please post how much physical ram you have.

You have run a spyware and AV checker to make sure you are not infected, right? Defragged the drive? Ran chkdsk /f at a cmd prompt? Haven't messed with disk access rights like taking away privledges from "everyone"? You have looked at what is loading in your startup? No big programs going into memory on startup?

you failed to mention how much memory (ram) you have to begin with.

But what is really important here is how much AVAILLABLE MEMORY that you have.
start>programs>accessories>system tools>system information....scroll down to the bottom and you will see how much ram you have and also how much "availlable memory" you have. If the available memory is below 100 then you should be looking at upgrading your ram.
Freeing some of the memory with commercial programs is an option but really doesn't work that well in XP.

David-

This is most likely one of these 2 problems: 1. You are ruuning out of Hard Drive Space where the system is set to use Virtual Memory.

2. You went in and mannually changed the setting.

FIX: ---> Right click the My Computer icon on the desktop and choose "properties" then click the "advanced tab" then click the "settings" button under the performance dialog. In the new window click the "advanced tab" at the bottom of this tab is the windows virtual memory setting area. Click the "change" button --> you will see a list of the drives on your system. Click the "c" drive (so it is highlighted and click the radio button "system managed size" then click the "SET" button. You shouldn't mess with Windows Virtual Memory settings unless you have more than 1 gigabye of RAM. If you have more than 1 hard drive installed complete the steps listed above on all of the drives.
If you have a ton of RAM like my machine you can choose to set custom sizes. I have 1.5 GB of DDR2 PC3200 RAM and my c drive setting Minimum 2MB and MAX 1900MB. Microsoft does NOT reccommed you adjust these settings, however a good rule of thumb is to set the VM only 1.5 times the ammount of RAM installed if you have a minimum of 512 MB.

Hope it Helps

I would have to disagree with the above recommendation despite the credentials.

I won't go into all the reasons why but suffice it to say with 1gig of ram you can despense with the pagefile. Yes that is right, no pagefile.

If Microsoft, in all of its wisdom, didn't want you to be able to set "no pagefile" they would not have provided the setting for it. No pagefile is one of the possible three choices.

It is completely false assumption that you have to have a pagefile. It simply isn't true. See previous statement.

Now running out of space is a possibility. The clue is that you can't make your pagefile larger than 576meg. But something has to be hogging that much of pagefile ops or you need more pagefile due to lack of physical ram. Hence the questions.

But then any of my previous suggestions to try/answer may have revealed the real problem(s).

I will haveto back wanderer on this one !!!

I have just had same argument in another post who said I knew nothing about page file etc.

But I have 1 gig on raid 0 and I run without it.

With 1 gig of ram or more yes you can run with no page file.

A bit of a risk yes it is but as long as you save your work at regular intervals and close all programs before shutting windows down you shouldnt have an issue.

IF IT AINT BROKE, DONT FIX IT - SIGNATURE COURTESY OF BUZZ187

I have been without a pagefile since 512meg. I'm at 768meg now. Over a year XP has booted faster and run faster. It is VERY stable and this is a microsoft product I am talking about. I do video editing, gaming, watch TV/dvds, internet, or whatever and have never had a crash since going to no pagefile.

If you do understand pagefile operations then you understand how important it is to do as little to none paging. It is the slow mo of your system

Not sure where you are coming from sneaksuit. No arguements here. And we are all waiting for David to post back with answers to the questions like how much physical ram.

I couldn't find your thread or I would have offered you some suggestions.

Have you reviewed my first post here? Post back with the answers and I will see what I can recommend.

Ok, sorry for getting aggrivated...I'm just getting fed up with my computer because I can't figure it out. I've had 384 ram for 3 years and it's always worked great. My CPU is 800 mhz. I didn't change any settings on my pc before the problem started. It just keeps getting a window that says my virtual memory is low and that windows will increase my paging file. If i reboot everything will run great for about 20 mins then the same thing....and the CPU will run at like 100% and everything is so slow. I checked programs running and there is nothing not supposed to be there. Checked msconfig. Virus check ok. Adaware check,hijackthis check, cwshredder check, all found stuff but problem persists. I am beginning to think ram is just getting old and not working.

Doesn't sound like a hardware problem but a software one. If it was physical you would be blue screening all the time.

Do you have the same issue if you come up in safe mode? If not than you know its something that is loading under a normal boot.

Have you ever done a system state backup? That would be easy to restore you to a known good state.

You could have a corrupt pagefile. This is when you move everything out of the startup to the desktop. Set the pagefile to no pagefile and reboot. Defrag the hard drive. Once complete remake the pagefile and reboot. You have enough physical ram you should have no problems running without a pagefile.

Lets see where this takes us.
