my pc came with AGP 64mb and it's no good. I upgraded to PCI 256mb. It's was just plug in and hook monitor to it and works for like a month. woke up one morning and the pci card wont display no video.. hook monitor to AGP and it works. unplug/plug in again.. the fan is running but no video any idea? i didnt install any drivers, is there anything else i can check or is that card really dead? brand new card in a month? i checked bios and dont see option do disable AGP thanks!!!
