Hello,
I installed a new invida GeForce 7600 DDR3 Graphics Video Card 256MB PCI Express on my m8400f Desktop PC. I have been using my motherboard video since my last video card failed a year ago. After installing the new card the computer instantly shuts down when turning on. I have a 300 watt power supply with 25 amps on 12 volts. I don't know of the new card may be bad or the power supply is shutting down due to over current or over voltage. The last card was a similar card which came with the computer. It was an invidia geforce 256 mb pci express which when it failed it did not shut down the power supply but had lines in display. I don't have another computer to test the card in. The place I bought it from is going to replace it with another new one to try. The computer is about 3 1/2 years old which I bout brand new.
