Hello! About a month ago, I discovered an old HP laptop of mien that was running Windows 8. Within the first week, I deleted all my old stuff and began replacing it with newer stuff. (games, apps, etc.) I opened up a game and played it briefly, but in the middle of playing, I shut it off to attend a matter that was going on elsewhere. When I returned to the laptop, I turned it on. Then the first problem began: The laptop was stuck in an Automatic Repair Loop where the loading screen for Preparing Automatic Repair pops up, then the screen goes completely blank. I spent the next 2 days reading forums, watching videos, and trying to fix it, but to no success. I tried a Factory Reset, but it wouldn't open. I tried resetting the Power, but it wouldn't work. After trying a dozen things, I became frustrated. So (first mistake) I just began pressing random buttons and clicking on things. Eventually I pressed F2. Then a screen appeared. I looked it up and one guy said it could potentially help my problem by messing with the BIOS. (Second Mistake) I ended up clicking on "BIOS Roll back" (or something) and the computer began loading. (Third Mistake) Event though it said, "DO NOT SHUT OFF WHILE LOADING," I shut it off anyway. The next time I turned the laptop on, the screen was completely black and nothing popped up at all. I finally decided I should stop messing with it any further, so I came here. How can I get my laptop to work properly again? I don't care if I need to delete all my personal information to fix this, for I can easily download these things again. Please help me. Thank you.
