Acer Aspire 7750g / Can't Enter Safe Mode (Kernel Data Inpage Error)

I have an Acer Aspire 7750g laptop for like 5 years now. Updating it's graphics card would result in having lines randomly flicker all over the screen horizontally. This is the reason I did not update it's drivers. Now that Windows 10 has released, it seems to have update it automatically which is irritating. I've searched in the internet some ways to fix it and tried one of them: Underclock the Memory Clock by 50 MHz in MSI Afterburner. This did not work at all. What I have done is I have underclocked the Core Clock by 50 MHz aswell and still no result. I've kept these two that way and restarted my laptop to hope that this might fix it, I was wrong. Now I can't even boot into windows. This is what I get when I try to boot into Windows: [URL]

I have tried going into safe mode and that's where I get the BSOD that says Kernel_Data_Inpage_Error. I have also enabled the low-resolution video mode, still no result.What I could do is reinstall the operating system but I'd like to keep that as my last option as I do not want to lose my files and I don't know if my windows 7 key will be accepted while installing windows 10 from a flashdrive.
