Loads of problems

Please, cool down or nothing productive will come out of it.

To me it looks like a driver problem, some corruption in the driver files maybe?
If you could perform these steps and tell us how it works:
1. Download the latest Catalyst driver from here. (Even if you already have it wouldn't hurt to redownload it)
2. Get Driver Sweeper and install it.
3. Uninstall everything ATI Display related.
4. You will most likely be asked to reboot your computer or do it manually. Now when your computer restarts press the 'F8' key (hold it) until you get several boot options. Highlight 'Safe Mode' and press Enter.
5. Back in Windows launch Driver Sweeper and check 'ATI - Display', click 'Analyse' (a list of driver related files will appear) and finally 'Clean'.
6. Reboot normally.
7. proceed with the driver installation you downloaded earlier.

If you have already done these things then forgive me, just trying to help.
