Before upgrade to windows 8 64 bit, i'v just downloaded and intalled windows 8 upgrade advisor on my pc to see if my computer is ready for windows 8. At that time, it said my pc can run windows 8 64 bit and those drivers all have upgraded to the newest. But now windows 8 64 bit just run about one week and there are so many annoying probolems such as BSOD occasionally and slow running speed that i have to return to win 7 64 bit.
does anyone know what's wrong with my pc or windows 8? if you want more information, plz point to me and many thanks in advance.
