I want to install my new ram I turned off my PC, took out the power cable, opened the PC, loosened the 2GB of ram, took them out, put in the new 4GB ram, tightened it, put on my PC, plugged it in... And my monitors turned on, yet it shows my processor unganged mode it detect my HDD but the cmos shows that it is checksum bad. Also, my keyboard is turning on but when I click the f1 or any keys after 5 or 6 click the keyboard will turned off? I experimented by either putting in my old ram or just using one slot of ram, yet it is always the same ending. Might I have damaged my motherboard or ram slots or what can I do to fix it?

if you unplugged the pc from the wall where there was no power to the mb. check online with the mb vendor that the ram you have is on there qal list or is supported. on the cmos issue check that the cmos battery is locked in and if there a 3 pin jumper the jumpers on the right pins. if there only two cmos clear pin check to see if you need a jumper on or off to have the mb work fine. at that point i would clear the cmos see if helps.
