Welcome to the forums, newcomer!
Are you out of warrant on the laptop? You should disconnect from the wall, disassemble the laptop, disconnect the laptop's internal battery and then remove the sticks of ram. While the power sources are removed, press and hold down the power button on the laptop to discharge it.
You can then turn your attention to the ram. Use a fine bristle brush to clean the slots of the ram on the laptop. Use an eraser to wipe the gold contacts on the stick(s). Wipe the contacts clean off of any eraser debris and then replace the stick(s) of ram to the motherboard. If the ram is soldered onto the motherboard, leave this step out.
See if you're able to get the laptop up and running.
