there is nothing wrong with the card.
the problem is your computer.
As I have said many times before, If you are to upgrade to ethier GF3 - GF4, your computer will need an upgrade just the use it.
To many people fall victom to this.
for 1, that processor is just too slow.
second that memory your running is probably pc100
Your bottlenecked.
My advice.
Take the card back. Save up for a new computer.
There is no other way..
