Explorer.EXE Not Working, No Application Launching After Theme Install?

Shortly after installing a theme (I can not remember as I can't get into the file system) which is as far as I can see a perfectly legitimate theme (recommended by a user from overclock.net) explorer.exe hasn't worked. I installed it, it asked me to restart explorer.exe by pressing the button. I got the error that it could not start. Itrecommended that I restart the computer before all changes take place. I assumed that I had to restart the computer for Explorer.EXE to work. It did not. At startup, the following happened and now does every time I start it up: (A note, sorry for the low quality photo's, I'm letting someone using my DSLR as they're on holidays.)Everything goes seemingly normal in the BIOS.FYI, the debug code on the motherboard is AA so all is fine according to the debug code.Just before Windows logs me in (just after the Windows logo at boot) there is a blacks screen displayed for a significant amount of time. As I have an SSD, it shouldn't be there and it shouldn't take that long.

Before I get to the desktop, the following errors come up:his is what the desktop looks at login. Firstly, there is not start menu - which means no explorer.exe. Secondly, why has this application started up? Nothing else seems to be able to but this application however manages to. Is it because it uses it's own UI? Nothing else seems to startup. Hmm.I press ctrl+alt+delete and the following comes up as usual: I click "start task manager" and the following error comes up then decided to start the computer up in safe mode.Same errors as before: This is what the desktop looks like, no start menu there:I press ctrl+alt+delete and the normal ctrl+alt+delete screen comes up. Same taskmanager error as earlier.I next boot into safe mode with command prompt. This time only this error comes up: (that is, unless I missed the explorer.exe error or I subconsciously clicked the ok button which is a possibility)
