Power Supply Switching

RAM stopped working. Whether it is due to faulty power supply switch on the cabinet or some other cause ?

Normally RAM cannot stop working. Even assuming that it did , I do not think that the computer will come and tell you that the RAM has stopped working. It is a possibility that the RAM Chips ( Sticks ) in your computer has become loose. If this is the case you can simply turn off the Computer, open it and re-seat the RAM Sticks.

If the RAM of your computer has become corrupted, first thing I would suggest that you do is to try it in another computer to see if this is the case. If it has gone corrupted or has become defective then I suggest that you replace it with same speed and kind of RAM.
