New Video Card = Big Problems

  1. I recently tried to replace my 6800GT OC (AGP) with a new 7800GS OC (AGP). I uninstalled the drivers for the first card and then shut the system down to install the new one. After I put the 7800 in, I tried to boot my computer. The operating system would not load and the monitor falls into a "power saving" mode as if the computer wasn't even running. I checked the connection in the back which turned out to be fine. I even took the liberty of going into the BIOS and checking for any descrepancies. Nothing. I took the 7800 out and reinstalled the 6800 - computer booted right up. I went into the device manager and deactivated the card with no installed drivers. I shut the system down again and threw in the 7800 (not literally) and got the same exact problem. It seems that I have had terrible luck with video cards for years and I am stumped once again. I would appreciate ANY help with this. Thanks in advance!

    System SPECS:

    AMD Athlon XP 3200+ (2.21 Ghz)
    2048 GB RAM - 2 DDR DIMM PC3200 sticks (XMS)
    K7M-NF18G Micro ATX motherboard - socket A
    BFG Tech 6800GT OC (AGP)

    Exchange the 'NEW' card.

    Are you sure you plugged in everything, including the 4-pin Molex cable required to power the card? Also, is ur PSU adequate enough for the card? If it's 450W+, then I think you should exchange the new card.

    The new card (7800) is securely connected to a 520W PSU. The fan runs smoothly so I know the card is powered. I am going to try reloading the CMOS to see if that does anything which I doubt will. Thanks for the fast help.

    What brand is the power supply? If it is a no-name brand PSU than it is likley the problem.

    The PSU is an ASPIRE (although I'm not sure that the company still exists). I used it to power my two previous cards and have had no problems. As for the 7800, I called BFG Tech and arranged an exchange. Thanks to all that helped out.
