Ok, so my laptop is possibly bricked, but I do not know. Anyway it all started with me trying to upgrade from a 32 Bit windows 10 to a 64 Bit because I though it was powerful enough, but the RAM was not enough so then it didn't work. It loaded really slow and took a long time to even work (and never started windows, but the startup did show) and then I ended up turning my computer off by holding the power button. I tried turning it back on and it did and it showed the windows 10 startup, but it made a crazy loud sound when it started to load and then again, I turned it back off. I then tried going into the options (you know, the ones where it starts up when you power it off at the middle of loading on windows and then powering it back on leaving you to those fixing options or something like that) and then tried to re-install windows 7 (as a downgrade), but it failed either once or twice. Then when I tried booting windows up, it was just a black screen of death and then it rebooted and kept doing it over and over. I also tried booting from a USB device, but the same thing happened, it rebooted back to the start. Ok, so does anybody know how to fix this (I cannot access the BIOS because the guy who put the BIOS password on it never told me or anyone else). This would be a great help to me!
