[Coron56]

Hello,
So this is my first post, normally if i find a problem Google has redirected me to this site and i have found an answer. But this time no such luck!
In short, When I try to play Most video games They crash either 5 mintutes in, in a cinematic or as soon as gameplay starts. The screen will freeze often go black and i find myself having to control alt delete my way out!
I'm not sure what else Information to give other than my specs so all questions are more than welcome and any help or advice even more so.

You might have too much other stuff running at bootup and causing conflicts. Look in your Tray and see how many items are running. Disable as many as possible.

You might also need to clean the system of junk files, registry errors, and other resource wasting crap. Run CCleaner and do the Clean and Registry both.

Run it again, until it comes back clean.

Did you uninstall any previous gfx driver before doing a clean install of the AMD driver? You may have some Registry conflicts between drivers,
1) Uninstall your existing driver and then run Driver Sweeper from Safe Mode: http://www.techspot.com/downloads/4266-driver-sweeper.html (use this link. some other links will install a bloated version)
2) Have DS find any AMD, ATI, and Nvidia graphic driver remnants it can and clean them out.
3) Re-boot and install the latest driver for your card and OS.
