5920g memory runs low, forced to close programs

If I leave the 5920G unattended for about 30 minutes to an hour, I am sometimes presented with a "your computer is low on memory" message where I'm forced to close internet explorer, windows messenger, and sometimes even the windows vista toolbar. I was originally on driver 169.09 i think, then switched and I currently am using 169.04. Before I had this error I think I was on any driver, even 169.09 and didn't get the error message. I have a T5250, 2GB ram, 8600m GT, latest BIOS. When I check processes now, (currently don't have a low memory error) it says Physical Memory 69%. Internet Explorer is taking 163 megs, desktop 50, host 44, a couple others at 22/19, and a bunch and 5,4,3 etc... I don't think these would add up to more than 300-350... Any idea it could be something to do with cache?

 

Sounds like a memory leak to me.

 

maybe a faulty stick of ram .....but i dunno!

 

i've had this problem before and i think it's because of MSN. update your bios and drivers, and get the new beta version of msn

 

Thanks! I'm giving that a try, just installed the new msn live.

 

nope, memory problem happened again, it seems to happen more when it's not plugged in, and the cpu speed is set down, as well as the graphics, but still low memory?? 2GB of ram, it's not expected, not matter how slow a CPU or Graphics card may be, any other ideas?

 

just see if it happens when msn live is closed

 

Sounds like malware.
