Mine is a HP Desktop system (Model Number : p6040in).
I used GEforce 8400GS Graphi Card for my system. The graphic card is gone bad as i keep on getting blue screens related to graphic card. I am planning to buy a new graphic card. I have DDR2 (2*2 Rams 4BG RAM in total ) in my system. I have Intel® Core™2 Duo Processor E7400. My system power supply is 450W. In my system i have PCI and PCIE slots. Can i buy a DDR3 graphic card and 450W or 500W power supply for my system. Will it support or do i have to go for only DDR2 Graphic Cards.
