Did a standard 4Gb memory upgrade to a PC, started it, got the case opened, and memory change message, however i cannot do anything as the machine will not respond to a keyboard.

 

Have went back to standard memory, and still the same.

 

One thing is before the acer screen appears the PC makes 3 low noise click close together, gets through the initial setup, and waits for me to do something, Caps lock is on keyboard as well, now stuck.

 

Help!!!!!

    have you tried to reset CMOS?

    disconnect the AC power cable, open the left side panel of the case, on the bottom of the motherboard you will notice a round button battery CR2032, take it off for 2-3 minutes, press power button twice then put back battery, close side panel and connect AC power cable.

     

    press power button and check if your are able to enter BIOS pressing Del key.
