Gigabyte 7970 won't work.
Hey !
I recently bought new Gigabyte 7970 OC, but i can't get it work.
The problem is that when i try to boot with the card, all i get is just serval restarts, and black display saying: "No input signal" My Windows 7 Ultimate x64 won't boot.
Fan's of the card do spin.
I used to have Nvidia gt 440, and it worked fine, but i decided to upgrade to beter card.
I used few other cards for test:
Club Raedon HD 3450: Worked
Club Raedon HD 5450: Worked
Raedon X850 PRP: Worked
(I was rely surprised about that, cause that card is so old, and it has been in my brothers toy box last 2 years. :/ )
And, Gigabyte Radeon HD 7750: This card has a same problem.
But i get 7750 work, by setting my CPU and Memory to default frequency.
However, this card causes system crash sometimes, when computer is highly loaded. (Gaming) Also i get weird pixel storm in games.
With 7970 I have tried also CMOS clearing, and CPU underclocking. Still same prob.
And what comes to bad drivers, it doesn't mater cause i can't go even that far in booting.
Sadly i don't have mobo's POST alarm, or any led's in it.
I don't have another rig to test if that is faulty card. I don't even think that is faulty..
My guess is that my PSU can be faulty.
That because all low end card works properly, and little problems appear with 7750 (400w)
Other cards only draws around 300w
My rig:
Windows 7 Ultimate x64
Intel core i7 3770
Corsair Vengeance 1600mhz, 32gb Quad
OCZ Vertex 3 SSD
GIGABYTE GA-B75M-D3H MOBO
Corsair CX 750w PSU
I really hope that i get 7970 work, before time go past it :/
Any help is appreciated !
I will post more info if needed.
Thanks.
PS.
Im using now 7750, and i did just, 10 seconds ago, get sudden black screen, where i saw my mouse, and it was blinking ?
Then i get message: "Google Crhome crashed, do you wanna restart it ?"
