PC Upgrades

I have Gigabyte MB with HD 7850 card and never had any troubles with it. Every time I want to update drivers I'm using AMD Cleanup to uninstall old drivers.
Maybe it's 7950 fault. Like MadMan said, I'd try to reinstall Windows. If it won't help and your card is still under warranty I'd send it.
Edit: Ninja'd.

It is alittle over half a year old, it ran perfectly on in my old AMD setup, but in the new Intel setup its f'ed up and can't run.

I think my best option is to sell on the internet or to a friend who's graficcard needs a serious boost

I have Intel too, i5 2400 to be exact.
But your situation is very strange indeed.

Maybe a strange one, but have you tried another PCi-ex slot?

PS Give the card a dedicated power rail from the PSU if possible.

I found this:
UEFI -> Advanced -> "Primary Graphics Adapter" on [PCI-Express]
It helped the guy who had no image on the screen at all and his situation was just like yours. He changed AMD for Intel, Installed W7 again and card stopped working.
But you have image so it probably won't help.

I could see it in the system when it ran with the win 7 basic driver

The card feeds of the same 2 (6+2 pin and 6 pin) cables that used to and now atm. powers the old 6850 card, just fine .. so i can rule that out.

As for the other pci-e slot, then i didn't try it because the card in that slot wouldn't be able to get enough fresh air and it was only pin'ed to 8x

Worth a shot, could you link to the place you found it on

There are 2 (x16 and x8) slots and one more 4x if i'm correct. You can at least try.
If it is a power issue or something else. 7950 is probably more power hungry. 8x and 16x will hardly be noticeable with the 7950.

And make sure your card is set as primary GFX in the BIOS, like V8 mentioned. Switching off the intel onboard is maybe not enough.
A bit weird that the older card is working fine and this one is not

The mobo.'s PCI-E slot are: 16x (gen3), 8x and 4x

And i have set the UEFI bios to Legasy mode, as you said turned of all intel onboard

I found it on Polish pc forum so you won't understand it (I guess).

Another thing might be your PSU that you ruled out. How old it is? Maybe it's slowly dying because it's getting old. 6850 needs less power than 7950 so it may run just fine with it, but not with more powerful card.

Yes it looks a bit like a power issue. Thats why i want Bear to make sure he uses a dedicated power rail on the 7950, where nothing else runs on. No HDD etc.
