Problems getting Watchdogs to run properly.

I have been having issues trying to get Watchdogs to run properly. At times the game would crash. Other times the system crashes. I would also get a message saying that the display or graphics adapter has stopped working and has now recovered. I tried reducing the graphical settings to low but to no avail. I have an iCore7 3.40 GHz Dell Desktop with Windows 7 64 Bit. I am using an XFX AMD Radeon HD 6870 1GB graphics card with a 600 watt Corsair Power Supply. I also have 12 GB of RAM.
Answer #1
have you tried updating to the latest AMD driver on your graphics card?
Answer #2
When I try to update the graphics card driver I get a message saying that the driver is already updated. I checked the requirements needed to run the game. The minimum requirement is a 1 GB graphics however; the recommended requirement is a 2 GB graphics card.
Answer #3
the 12 gb ram sounds weird.
how are they setup?
-4
-4
-4
-empty
or else?
same speeds and timing?
Answer #4
12 is not weird at all.
Graphic card stopped working mean its either overheating or something is wrong. Can you run other games without problem? Try an clean uninstall of the gpu driver then install it again.
Also check and see if your card are overheating or not.
Answer #5
I read issues with AMD cards. Keep an eye on driver updates
edit: is last update for your drivers 4/25/14? (web site) They need to get up to speed
