I also receive the same computer low on memory error message often after using my computer for a couple of days without shutting down (only hibernating). Sometimes it will crash some of my applications. But most of the time, Windows becomes unresponsive or very very slow. I have tried to shut down ALL applications. But still the memory low error can persist. Seems like the advice to close programs is not really the solution. I have done my own checks. I installed a memory cleaner which can display the status of the memory usage. Interestingly when such memory error occurs, I have found that this can happen despite usage of my 4GB RAM is <20%. On further checking, I found a consistent pattern that the error happens when my pagefile memory is >90+%. I started tracking this pagefile memory usage closely and found that it just keeps going up over time, it simply does not come back down even when u close the programs. In the end, I followed some threads and implemented a "delete pagefile on reboot" option and manage to clear the pagefile everytime I reboot. This will solve the problem for a few days but it will come back to haunt me again. It forces me to reboot, something difficult for me to do as I work on projects for long durations and I do not want to keep shutting down and rebooting!!
This is very very irritating for me!
While playing around with the pagefile (virtual memory), I also found that everytime I try to set the pagefile size manually (i.e. not auto set by system), the dreaded blue screen will appear. So I have also given up setting it manually. It seems to always be about 3456MB size thereabout.
Anyone has any solutions?
