Basically, I got a used 6950 for my friend. I tested it in my system. When plugging it in to my system and connecting it to a monitor, nothing would show up. However, I have igx on, so with the monitor connected to my IGPU (I have multiple monitors), I was able to boot into windows, and install the right drivers. Then, everything worked flawlessly and the monitor with the GPU would work fine. Gaming went perfectly fine.
Now, on my friend's system, we cannot do the same. His pc refuses to boot normally if the card is plugged in. It won't post. The work around to this is booting without the gpu plugged in, setting the bios to IGX, booting to windows, turning on safe mode, putting the card back in, and then booting into safe mode. From there, we can use one monitor with the IGPU, while the monitor connected to the 6950 stays off. This is pretty similar to what happens on my system, so I assumed it would work. I ran both the AMD clean up utility, AND DDU, and then booted into normal windows. From here, I turned off his wifi, his bitdefender was also uninstalled, but for some reason I couldn't disable windows defender, as it said another anti virus was running, even though we already uninstalled bit defender). I didn't mind that as I couldn't find another anti virus in his programs list. I then proceeded to install the AMD drivers. The only issue is, it freezes during the Display Driver installation. This isn't just a normal freeze or a crash. The mouse pointer automatically recentres when it freezes. The mouse pointer can be moved, but if it hovers over anything, nothing responds (ie hovering over desktop icons does not highlight it). Clicking is unresponsive, as are keyboard commands (alt f4, control alt delete).
Alas, after leaving it like this for 10 minutes, we rebooted. The system would not post. Thus, we had to repeat the cycle of taking out the gpu, booting into windows, turning on safe mode. With safemode enabled we could install the gpu and boot. Run the uninstallers, and boot back into normal windows. Install drivers never worked.
Any suggestions on why this is happening?
Note: My motherboard is an asus p8 h61 rev 3.0
His mobo is a much nicer Gigabyte z77x UD5H.
We also updated his bios to multiple newer versions. No success.
Both our power supplies are more than sufficient.
Why can I install on mine but not on his?
The card is a 6950 flashed to a 6970. It worked fine for me. We are also using the same drivers that worked on my system.
Possible issues are me having a relatively clean install of Windows (clean install when i got my ssd 6 months ago) and his being 8 years old and an upgrade from Windows 7 to 10 without clean installing
