My Windows XP system is generally stable, but if I leave it turned on for a few hours (especially if no utilities/programs are running), XP tells me that there's a virtual memory problem and shuts some vital stuff down.

Is there a fairly easy way to find out which prog is leaking?

You could try this: Press Ctrl+Alt+Del to get the Windows Task Manger up. Select the Processes tab. From the menu select View->Select Columns... then make sure the Virtual Memory Size is ticked on. You should see a column call VM Size appear in the listbox. Now, occasionally click this colum to sort it so all the memory hungry programs are at the top that way you can see which the culprit might be.

Something else you could try/check.
Right click on My Computer select Properties to open the System Properties dialog. Select the Advanced tab. Click the Settings button in the Performance group. Select the Advanced tab in the Performace Options dialog. In the Virtual memory group click the Change button. Select 'System managed size' and press the Set button.

It maybe that you have run out of hard drive space, check how much you have free.

Cheers StruggleDude, I'll check those things out tonight.
