I have a 64-bit Dell laptop which I recently upgraded from Windows 7 to Windows 8. Since then, it's creating havoc in my life. The Metro apps are not working, the system crashes once in a while, and none of my games are running because I don't have the correct drivers for my ATI 5000 series graphics card.
Some days back, Windows downloaded an update and prompted me to restart. After that day, whenever I log in and fire up my desktop, I get all kinds of blue screen errors. The most common one looks something like this:
Please tell me how I can fix this, optionally how to go back to Windows 7.
