As I try to boot my computer, it shows Asus logo, and the loading dots below it, and after that I just get this flickery blackscreen, where the screen is black and the back-light seems to turn on and off.

Now in most cases I would try Recovery or Safe Boot or Last Good Known Configuration. But that's the biggest problem, I cannot even access these, as the blackscreen error begins before I could even access the F8/Shift-F8 menu.

Little information how this started:
I installed Crysis 2, a game, with a downloadable installer, installed fine, played the game a few times, but as I noticed, it left it's installer files behind. I tried to delete the Crysis2Setup.exe , but Access was denies. I tried to delete it with Administrative CMD, but even that failed, then I downloaded iOBit Unlocker and as soon as I clicked "Unlock and Delete Crysis2Setup" . It gave me a bluescreen and restarted the computer. Since then I haven't managed to boot it due to the blackscreen.
I would understand this behaviour If I had deleted an important Windows file, but Crysis2Setup.exe is nowhere close to behind anything important for PC to run. However it does seem like there was something wrong with the file.

Windows 8.
