I'm new to hardware and i tried to upgrade the RAM of my Acer Aspire One A150B replacing the 512mb memory with a 2Gb one. it fits the slot, so i thought it would work fine... but when booting up the pc, the led that says the pc is on is working but nothing appears on the monitor, i checked everything and it is all connected well. When I tried reinstalling the old 512mb memory it booted up correctly. what should i do? why with my new memory it is not working? do I need to overclock? please help me with a step by step guide on how to solve this problem.
thanks
