well i have asked this somewhere else but nobody replied. Ok so i have 2 sticks of ram, 1 is 512mb and 1 is 128 mb. I use a program called freeram and it always says i have 512mb on startup, so thats fine, usualy stays at 300-400. After i was backing up a copy of gta while i went to sleep i woke up and the ram said 20, so i was like ..ok restart. I restarted and now my computer freeram says i only have 100mb !,in control panel/system it says i have 256mb, it used to say 512, whats going on!
