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?
If your mobo has a on board gfx you MUST disable it in bios before installing the ATI card. Best thing to do is boot into windows with the mobo gfx uninstall all gfx drivers for it reboot go into bios and disable the onboard video shut down the machine and then installed the ATI card and boot up.

Windows 7 64bit
disabled the mobo grafix

I'm aware of disabling the built in motherboard graphics card. I boot up in win7, remove the drivers, shut down, enter bios, disable the mobo graphics, save and reboot, and windows 7 never fully loads, blue screen. Also crashes in Safe mode. I think there maybe an issue with Biostar TA790gx /w a Sapphire 4870 and Windows 7. I picked up a evga 260gtx, and installed it on the same system and it runs perfectly.

Windows 7 64 Bit

Hi there,
I have encountered the EXACT same problem with my Sapphire 4870 and my new Windows 7 build.
I get to the loading operating system then the screen goes black and monitor goes to sleep.
I had an old XFX Alpha Dog 8800GT lying around put that in and it starts right up. I am so bummed I love the 4870 and can't seem to get it to work.
The BIOS is set to PCI-E, not onboard graphics, I have tried full clean install etc...NOTHING is working.

Anyone resolve this issue short of buying a different card?

BTW my 4870 worked fine for me for almost a year no problems...The card was working yesterday on my old XP build and Gigabyte board.

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.
Its meant to say that. I have a GigaByte 1GB 4870 and it runs smooooooth. have not had a single problem with it, GigaByte all the way people!!

@ randomk - do I dare ask if you have downloaded the latest Win7 drivers from ati?
