Last response: in Graphics & Displays

Hello, i am running a hp pavillion with an integrated nvidia 3600 vid card. i recently installed a radeon 3650 1g vid card. after running for a week i noticed that the card was shutting off and repairing it self(?). last night the monitor stopped receiving signals. ( samsung sync master 920nw). it has a blue power button that blinks like it is in sleep mode. i bought a 520w power supply and installed it.
after about 10 min the moniter will come on

any ideas as to how i can resolve this problem

Is the Monitor new? If it is, it may be also the Monitor that is somewhat broken, if you are sure that it is your new AMD Radeon card, return it if it is under warranty.
It may be an driver issue. Did you install official Display Drivers from directly AMD? Don't ever install display drivers from Windows Update.

Also you could buy an HD 6570, which is faster and cheaper than an 3650.

Hope it helps! :) 

thank you for your replies.
the monitor does turn on after about 5 min or so. works fine until i try to play a real game (not that facebook stuff.)
then it seems to goto sleep for a while.

i did buy that radeon 6570 last night but i get the same problem after i install it.

Are you sure that both of the cards doesn't work and does the same problems? What is your motherboard? Some older motherboards may not be compatible with newer graphic cards...

Also, what is your Power Supply (PSU)?
