I need some help here to deal with a blue screen error on my pc. It started automatically upon reboot. The error code that I facing is 000000f4. I cannot recover my system from the same. I need some help here. I am having lots of data in my system. I cannot backup the same also. I had tried to boot in safe mode also but still the error appear on the screen. It looks there is some serious bug in my pc. Recently I had just added a new printer and this problem started. Is anyone having more detail on the error.
