Blue Screen of Death. Happens at a particular time

I have had this hp envy for about 4 to 5 months now. Off and on the blue screen of death occurs with the same error critical process died. i have had this problem since February and it has been off and on. I tried to fix this about a month ago. It seemed to be working for about a month until last night. I notice that this happens most consistently when i have the computer off and i plug the computer in and turn on the computer. it usually happens a few minutes after startup. If i plug in the power chord while im using the computer the error never comes up usually. Like i said, the only time it happens consistently is when i plug in the power chord before i turn on the computer or bring it out of sleep mode. the blue screen also comes up when i plug in the power chord during startup. i have run the system scan command line and everything seems fine. i have also done a quick hardware scan and everything is fine. i have considered doing a full hardware scan to see if there is anything. I don't think that updates are an issue. i just also updated all the drivers last night as well. my last plan is to do a system recovery if all fails. hopefully you guys might have some ideas. Thanks!!!
