I changed the ram and hard drive and it won’t start up

I installed a new ram and hard drive but it will just blue screen when ever it boots and gives me kernel security failure error code so I can’t seem to fix it?

@sdhd …sounds like it doesnt like the new memory or it needs to be reset. have you ensured you are using the correct ram and they are paired correctly? have you tried using the old hard drive and new ram or old ram and new drive to see which is the cause? have you cleared the cmos by removing the battery and shorting the positive and negative terminals to reset? try these and post back with findings for further assisatnce.
