You can find your drivers at AMD Drivers & Downloads Radeon HD4870, enter your operating system, 32bit or 64bit, and download.

Good luck, hope this helps.

ive done that does the same problems ... :/

Soon as i instal the drivers it ****s off

Not to try and revive a "dead" thread... but my other computer has the same issue... except I can't even get Windows 7 to load.

To install Windows 7, I had to do a clean install and remove the ATI vid card and replaced with NVIDIA 8800 GTX Ultra I had laying around.

I tried to re-install the card after Windows 7 was installed and I ran into the same problem:

The Windows 7 logo appears on the screen and starts to load windows... a second later the screen goes black and the monitor goes into "No input mode" and nothing else happens. I hard reset and it keeps happening over and over.

I think Dave76 may have mentioned it having to do with the rig having 4 gigs of RAM and 2 gigs on a video card on a 32bit system.

However, my other computer also has 4 gigs of RAM and the SAME vid card (just the X2 version that is stated as being supported on Microsofts webpage) and it runs just fine on a 32bit install.

If you can't install the driver for this card easily, there might be a physical problem with it. Or your system could just be bonkered. Contact ATI/AMD for an RMA offer.

I'm actually starting to think that I may have a DOA card. When I first installed the drivers for this card on XP 32bit, it stated in the Device Manager that is was "Radeon 4800 series" instead of saying "Radeon 4870". Also, when I replaced the card with the older NVIDIA card the boot up was LIGHTNING fast. It always seemed to hang with the ATI card... I never would have noticed had I not replaced the card with the NVIDIA one to install Windows 7.

Yes, I'm really starting to think it may be defective. Odd, the RAM I bought was supposed to be 3x 2gigs... but one of those was also defective so now I only have 4gig. Strange.

I'm having the same problem with Windows 7 64bit.. System boots up and runs fine /w motherboard gfx, biostar 790gx, once I install the 4870 in the system, and try to boot, it crashes. I can't even boot in safe mode. Is there a way to not detect hardware changes during boot, and run on generic vga driver?
