Last week Sunday night, I was shutting down my PC, but it froze on the "Windows is shutting down..." screen. I had to resort to using the power button to turn it off. The next night, it did the same thing... and the next night after... Then, on Wednesday afternoon when I attempted to turn it on, it froze on the boot screen where it says the computer company (in my case: HP), F10=Recovery, etc. My computer fan is really loud and I could hear it starting on, then turning off... starting on, then turning off... and so on while the computer was frozen at the boot. I'm not able to push F10 or F8 or whatever to activate safe mode or anything else. Can anyone help me? There's a LOT of files on it that I need. Any help is appreciated!
