Games won't load after installing SP1

[slick415]

After installing W7 SP1 x64 through automatic updates, none of my games (CS: GO in Steam, Heroes of Newerth) will load. The first time I encountered this problem, I decided to format my SSD but the same issue again after installing SP1. Thinking it might be a video driver issue I've tried installing an older driver but the same thing happens. I decided to uninstall SP1 and all my games are working again.

I never had this issue when running on a HDD. I just installed a new SSD a couple of days ago, doing a clean install of OS.

System Specs:
Windows 7 Home Premium 64 Bit
i3-540
GTX 460
Samsung 830 256gb SSD

Reinstall your DirectX with the latest version after you install SP1
Also, after you install SP1 you have to install all the updates after that as there are updates to fix the SP1 update lol.
