Since liek halfway through the day my physical memory that's free starts out fine but then eventually hits 0 and the cache has about 2 gigs afterwards. Total of 3 gigs ram and vista using 1 gig so 2 gigs total for free use normally.

I can open some programs like another Internet browser but i don't wanna try opening anything large.

I tried uninstalling programs/games I didn't use anymore but it still dropped. So I tried turning off SuperFetch too which the free memory did stay around 200-300 mb's but that's it and after a bit it hit 0 which is right now.

When i open windows task manager the green box under the performance tab with the memory is at 1.38 gb's at the moment, which is not 1/2 filled but yet still at 0 free space of physical memory.

The first time it happened I went to log out since I didn't know what it was and then log back into my account on the computer but as I was logging out I got a blue screen and the reason it said was "Memory_Management" but have not gotten it since then.

Thanks

I have only been using Vista for a couple of weeks so am slightly hesitant about offering the following.
Boot Vista twice. Apparently it sets the ram different to other previous Windows.
