What do you mean by "Memory Card?" You said "even i did reset the BIOS of motherboar". How did you reset the bios if nothing powers up when you press the power button? Life's more painless for the brainless.

You shouldn't have interrupted the power without shutting completely down. Unplug the computer again and try reseating the memory sticks. You probably don't have them inserted completely. You need to push fairly hard and you should feel and hear a snap. Make sure you didn't turn them end for end. They are not the same at both ends. Look at the notches on the bottom of the module. They MUST match up with the bumps in the slot.
