Worse game performance after fresh install of Windows 7 on new MOBO

Hello all, I'm having some performance decrease on my new Build. I bought a new motherboard, Hard Drive and CPU Cooler and had to re-install windows to get my new board to work properly. I've noticed that now in League of Legends my frame rate is around 40-70 when I used to have a constant 150+ even in hectic situations where lots of things were going on at one time. I have the latest AMD Drivers, 13.1. I have tried reverting back to 12.10 to see if its the new version that's causing the problem, but its the same.
My system:
AMD Phenom II X4 945 @ 3.0GHz
MSI Radeon 7770 @ 1000/1100
8GB G.Skill @ 1333MHz
ASUS M5A97 R2.0
Windows 7 Home Premium x64 genuine copy
Corsair CX430

  1. Hi :)

    You DID install ALL your motherboard drivers AFTER the 7 install and ALL the updates to SP1 and right up to date of course ???

    All the best Brett :)
  2. I just checked and I actually don't have SP1 installed, so I install that and do a fresh install of the latest motherboard drivers on ASUS website, thank you for the quick reply.
