For XP u can use this. For 7 use.
That are nvidia drivers, there are very good for your card.

contact the shop / place you purchased it from and they should be able to give you info of where to send it and what to do - they should have a section on there website where you can go through the return process and you will most likely need to get an RMA number to authorise the return / replacement.

If the problem occurs right as the windows desktop comes up from a cold boot, it is not a cooling problem, the card hasn't had time to heat up yet.

You probably have a bad driver, download at http://support.asus.com/download/download.aspx your series = Nvidia, model=en7200 series and install new drivers.

Also, check to make sure the card is fully inserted in the AGP slot, I've seen some odd things happen because of a loose card.

Your PC keeps restarting because while playing your video card is highly solicited,and this causes overheating. The solution to your issue is to buy a cooling fan and attach it to the cooling grid.

If this solution worked for you please rate it. If you require further assistance feel free to post a followup comment.
