Download driver booster and scan for outdated drivers in your computer. It's an easy programm to use and it's free. If you update all your drivers and still the problem presists I would say the problem is with HDD not with GPU, and should be scanned for bad sectors and get defragmented. Personally Smart Defrag has helped me a lot with defragmentation.
You need to remove your older GPU drivers if that was not done automatically. Sometimes the older GPU drivers will mess with the newer ones.
1+ Yeah i readed some comments bout that before but when i putted my gpu i was so exsisted cause the acer g3620 mobo's don't support 700 series but it runned in mine and forgot to do that will try later though and i'l type here!
