Problem Event Name: StartupRepair Offline

Hi All, I have a T2 Series Asus, quite an old model running 32-bit Windows 7.

Computer just all of sudden turned off randomly. When i try starting it up it says 'Starting Windows' and when carrys on it just loads to a black screen, where which it just stays at this point. So I have unplugged the computer from the power source and tried starting the computer several times through Startup Repair at where it keeps failing to repair, It says "Startup Repair cannot repair this computer automatically". This is the problem signature:
