Hi all, so I recently got 2 sticks of 4gb crucial pc3-8500 ram to replace my hyper blue 4gb single stick. When I installed the new ram the computer turns on, but the keyboard doesn't light up and nothing appears on the monitor. It works fine with the old ram, and I checked Crucial's website which said it was compatible with my gigabyte GA-990FX UD3 motherboard. I tried draining the cmos for 15 minutes, but that didn't work. Any help is appreciated !
