Hello I purchased a PNY nvidia GeForce 9800 GT EE 1024 Video Card. I Installed in PCIe slot and when I booted computer card would not post. I upgraded my PSU Is an Antec 780 with 12V - 25 amp available. Have an Ahtlon 2500mhz dual core on asus M2V-MX SE M/B. 4gb ram. Is like there is no video card in the slot. If any one can help contact olcorky_99@yahoo.com Thanks
