I've been using two RAMs, one is of 1 GB and the other is 512MB. My computer used to show the amount of correctly as 1.5 GB a few days before but now, whenever i turn on my PC, the total RAM is showed as 240MB, I've even did some testing by having a single RAM, but no matter which RAM i plug into my dock, it shows only 240 MB.
But at times when I'm lucky, the total RAM shows up correctly as 1.5GB, Guys please help!!!
