When I turned on my computer, it was successfully booted up to the Windows Logo and then suddenly restarted.... there, in the menu with the details related to RAM, HDD etc that shows up at first when the computer is booting, My RAM was shown as 1024MB . (I have 2048MB of RAM.... and after the computer booted up to the desktop, It again restarted... and then the RAM was shown as 1.5GB ( I have TWO 1024 MB RAM modules). And when the system booted up to the Windows logo, it again restarted and there the RAM was shown as 1 GB again. This time, the OS was successfully booted up to the desktop and when I checked the properties, the RAM was stated as 1GB. What has happened to my RAM ?
