I have a Toshiba satellite C655_S5061 with windows 7 64 bit SP1 installed on it. It has 4 GB RAM.
Strangely only 2 GB of RAM is visible, I confirmed this through BIOS, resource monitor and CPU-Z.
Will a BIOS update solve the problem or is that a memory module might have gone bad?

Power off the unit, unplug the AC & remove the battery, remove both RAM modules, replace one RAM module in a different slot, replace battery & AC, try to boot up again. Repeat this process until you have tried each RAM module alone in each slot. Keep careful note of which RAM module(s) and/or slot(s) is/are working.
You want to try to figure out if you have a bad module, a bad slot, or possibly something else, like maybe the RAM just needs to be reseated.
Please let us know what happens. Good luck.
