Syswow64 corrupted + fatal system error screen

[diamond0099]

First i'd like to say sorry for any crappily spelled words. I am typing on a tablet because my PC has problem mentiomed in title.
I started my pc after a long trip today. During initial startup all was ok. It then lagged as usual on logon. When it finally showed the screen a few errors appeared as well. I dont remember exact contents (can start pc and write down exact messages here if requested) The first was something about the syswow64 directory being corrupted. If you pressed ok it would show another one and if you pressed ok on that one it would show the syswow64 one again and so on. I could however log in fine. It made the login sound, wallpaper and taskbar and everything showed up. It got to rainmeter before it displayed the other variant of the BSoD which only has a few lines of text with no instructions of any kind and shows up if theres a FATAL system error. This is what I mean: http://img.bhs4.com/16/8/168aa6fc40da4c617da08a19fcb9f4a85dde4b48_large.jpg It didnt look exactly like the one linked though. Again it said something about syswow64 and then disappeared. Again if requested I can try and write down the error code. Im really afraid I bricked my PC. I looked it up and people were having similar problem but not with syswow64 itself. Some people had the file mfc45.dll corrupted while others had opencl.dll broken. As mentioned before I dont remember the exact contents of the errors so its possible im actually having a problem with the files mentioned. I will check the errors later and post their contents as well as the fatal system error screen error code. I did some more googling and people were suggesting sfc scannow but if the entire syswow64 folder is bricked and not just a file then im pretty sure I cant do that. Will update on the issue later. Thanks!!
edit it is also worth mentioning that the last time I used the PC, I disabled UAC. Also note that disabling UAC needs a restart and this started happening after I turned off the pc and started it again later.

I just started my pc to get the errors and the code but it wanted to do chkdisk. I had it do it hoping that it would fix at least part of the problem.
Turns out its my HDD thata bricked. It said something about not being able to access a volume of the disk. I tried to write down the error code but I wasnt fast enough. It started with "766". Please help.
