Hello, i really need some help i have done just about everything and still no luck on this problem, i have a msi radeon hd 7970 boost edition/overclock edition graphics card, on the first install of the drivers it worked great, however the next day when i booted up i started to run a game/browse the web and i experience severe lag, games are unplayable and just regular browsing is pretty much a no go, the only possible fix and this dosen't work all the time as it is, is a reinstall of the graphics drivers, however i am faced with the same problem upon every reboot and it is quite a problem, i have tried countless fixes, i have wiped old drivers installed new ones, i have tried around 4 different drivers on clean installs of windows and still faced with the same problem. i have an intel i7 4700 with 8gb ram and a 750w psu and i don't see my pc as a problem as it is only a week or so old. please if anyone could help me i will appreciate it so much!
