hi, new user here. i searched the forums but did not solve my problem. When i shut down my pc, it does not SHUTDOWN, i see the blue screen with shutting off message but it stays around 5 minutes and then a blue screen of death comes with all the error messages. i restart using the power button it restarts but the same scenario REPEATS. i tried to apply other suggestions on registry like not clearing registry etc.. but did not help.

this started like 1 day ago, i did sytem restore back to last week but also did not help. one more thing since this issue started, when i restart my pc, after welcome message the screen goes black for aorund a minute i can MOVE the cursor but that is it. after a  minute the desktop comes back and everything is normal. i did virus scan nothing

thanks alot for the help
adding the error message from event log. i searched for this kernel power error but couldnt find much other than it is related to system can not shut itself down
