ATI 5770 Won't start up

So I uninstalled my Nvidia 7800 gt oc for my new powercolor ati 5770 radeon HD card. The PC starts up but my monitor does not. When i try my nvidia card again it works fine. And yes I have got rid of all the nvidia drivers previously installed by going to devmgmt and wiping them out. Here are my PC specs.

-MOTHERBOARD-
Board: ASUSTek Computer INC. LITHIUM 1.04
Bus Clock: 200 megahertz
BIOS: Phoenix Technologies, LTD 3.08 09/12/2005

-CPU-
2.80 gigahertz Intel Pentium D
16 kilobyte primary memory cache
1024 kilobyte secondary memory cache
64-bit ready
Multi-core (2 total)
Not hyper-threaded

-Power supply-
TR2-430W Power Supply

Any help would be much appreciated. : )

  1. Anyone?
  2. New card is PCIe 16x 2.1 I assume?
  3. yeah my my motherboard is backwards compatible, it fits in fine.
  4. Didn't ask if it fits.
  5. Install latest AMD driver 10.12 from AMD.com. Also, make sure that the 6-pin 75W power lead is plugged into your 5770.
  6. Can I install ATI drivers while an nvidia card is inserted though?
  7. I thought your nvidia card was taken out. Any case, you need ATI drivers for ATI cards.
  8. I have to put it back in for now, because when the ATI card is in, the monitor doesn't turn on. I can hear the ATI cards fan but the monitor does not respond.
  9. You can install the ATI drivers with the nvidia card in. When you get the ATI card working, uninstall the nvidia drivers if you have issues. I've read that they don't like each other with certain settings. Good luck.
  10. Sorry. Lack of drivers won't account for it not working in boot/bios. You should at least get that. Still guessing its a PCIe 2.1 card in a PCIe 1.0 board. It will fit, but it might not work. Either return or install newer bios to see if that fixes it.
  11. how do I do that?
  12. check your mobo brand site for upgrading bios and check releases logs for pcie 2.0 - 2.1 also check ur user manual and see if ur pcie is native 2.0 lower or higher

    in the manual check for expansion slots

    also does your ati vga have pcie aux power connecter which i guess it has and if its plugged in?
    do you get a bios code error ? or post bios signal?

    I don't knowif I'm getting any kind of error because the monitor doesn't turn on at all. I get no signal.
  14. I guess I'm done helping in this thread. If you're not going to answer the questions, there isn't anything I can do.

    My best guess based on the available data is the card doesn't support your motherboard. Not because its an AMD/ATI card, but because it's a PCIe 2.1 card and you have a 1.0 board. Yes, it will fit in the slot. But not all 2.1 cards work in 1.0 boards. If you want to get a signal, return the card for a 1.0 or 2.0 card. That or update your board. Good luck, I'm out.
