I have recently installed a new graphics card the Sapphire Radeon HD7770 FLEX EDITION 1GB GDDR5. My previous graphic card was a NVIDIA GT545 which was installed by dell when I got my computer. Now since installing the new graphics card even though my computer works fine on few occassions when watching youtube videos my computer screen goes black and freezes, the same when surfing the internet and logging onto website that have videos my screen crashes computer turns off restarts etc but no BSOD. My computer is a DELL XPS8300 Intel I7 12GB / CPU3.40 / 64Bit windows 7. Are there any specific settings or configurations I need to do in order for this graphics card to work correctly on my computer. Any help would be very much appreciated thankyou.
