Error 3FO

[debbiemavro]

Hello, 

I would be really grateful if someone could help me solve this problem I am having. Any suggestion is welcome!

I bought this laptop in January of 2020. Until November everything worked perfectly. In November some blue screens started to show up here and there, but after the laptop restarted it worked just fine. The real problem began in December when right after the bluescreen “WHEA_UNCORRECTABLE_ERROR” I would get a black screen with the “Boot device not found 3F0” error. The weird thing was that after I would press the power button twice the laptop would start up normally. I tried everything i could find on the internet but it still didn’t work. 

I then visited a local technician, and after he ran some tests told me that it was a hard drive failure so i had to change the hard drive. We did that, but still I would get the same black screen. It even got more frequent; up to the point where the black screen would not disappear no matter what i tried.

I contacted HP technical support in Greece and after trying everything they could think off, they suggested 2 electronic retailers who provide certified HP technical support and can check the laptop for any hardware problems. Following their advice I shipped the laptop to Athens (capital of Greece) to get help. After running some hardware diagnostics tests, they decide the laptop is fine, they perform just a clean install of Windows (like we haven’t tried that a million times already). I tried contacting them to explain that we already tried this solution, but their answer was that they couldn’t find anything wrong with the laptop so they sent it back. The moment i press the power button i get THE SAME F*** BLACK SCREEN. I shut it down, press the power button again and the black screen is gone.

I tried using the laptop nonetheless and at some point I got a notification of a system update. I chose to install it and the moment it boots to update mode I get a blue screen with the “WHEA_UNCORRECTABLE_ERROR” . 

Please if someone has any idea how to fix this please let me know! Thank you in advance!
