Gigabyte 7950 Windforce Failing

Hey Guys,

I was just getting ready to put the finishing touches on my new build. everything was finally purchased, when I ran into an issue.

Upon fresh install (windows 8) everything was running great. I upgraded the video card drivers from the amd website.
Using Display Driver ver. 13.152.

Tried some BF3, Guild Wars 2 and a few games from my steam library and things seem fine. Checked the temps in the AMD overdrive and that seemed fine too.

So on day 3 of my new build it crashed. I was playing FFXIV and bam straight to the desktop. Tried running it again. DirectX error, Tried BF3, The application has stopped responding, seems now like everything 3d related crashed.

So I now go to Reboot the system. It gets to the spinning windows 8 logo and then starts to flash my inputs on my LCD. Like I get a black flash, then my screens lcd goes amber, then blue, a flash, and repeat.

My next step was to enable my CPU's onboard Intel HD Graphics.
I left a HDMI cable in the 7950 and hooked up a 2nd monitor to the On board.

On boot, windows 8 now worked.
Once inside windows I checked the Devices to see if the 7950 was still detected, which it was.
I went into the resolutions and tried to enable my 2nd monitor on the 7950.
BAM everything goes black, and now both screens are flickering.

Reboot Again:
This time I remove all the amd drivers completly.
Still no luck.

And that's where I am right now. Normally if this were a clients rig my mindset would be RMA time. but being my own and not wishing to spend a billion Canadian sending it back to Gigabyte I figured I'd post here for some 2nd party advice.

Some other notes:
With my build I am using Silverstone white GPU PSU extensions. But removed them for the process of the testing.
The MB is new and I did make sure the PCI-E connector on the 7950 was clean so no dust or artifacts should be a problem.
Other PCI-E devices do work in the port so I don't think it's the board.

Matt.

[EDIT: Will UPDATE my SIG with my current build for ease of helping]
 
Real basics here but is the cable ok?

I got worried the other week because I only have one HDMI cable (until yesterday) which is swapped between the PS3 and the PC, well last time I put it into my 7970, nothing happened, it seems it gets loose in the slot or something now and just needs a slight wiggle and then it works.
 
The cable should be ok. I used an extra Dual Link DVI cable on the 7950 after it first failed figuring the same.
 
Hey mate, what power supply are you using?

And have you tried to use the GPU in a different 16x slot, just to rule that out?
 
Hey Feronix!

I just updated my sig with a bit more info.

But the Motherboard is a new Gigabyte Z87-WIFI, so I unfortunately only have one PCI-E to work with. I'm also moving back from a gaming laptop, so my builds pretty much the only thing I have to work with test wise. at the office and work we just have VERY old workstations, nothing with a large enough power supply to try to card in, and more than likely the boards there at pci-e gen 1.

My power supply is a Corsair CX600.

I'll keep everyone up to date, I think I have a CX500 somewhere from a old build in the parts pile. I'll update the status after work. May also have a friend that will let me try the card in his rig.

hi mate

I have the same 7950 I've never has an issue with it and I have a 3570k a z68 mobo and I have a cx600m my rig pulls just under 400 watts so I don't think its a psu thing going on I think its windows 8 I use widows 7 with no issue I know friends that run widows 8 and 8.1 and from what they said its just problem's all day long

I don't think there's anything wrong with your hardware I think its software
 
Well guys, an update!

Weirdly enough I found a CX500 at work that I didn't use in a build. Figured id bring it home and try it out. at the time I was just using the system without the video card. Put everything back. booted it up, seems fine. Apps were crashing every time I would run a app that needed video, explorer folders with thumbnail generation, anything video related. figured it may have been from me nuking the drivers. Downloaded the latest Beta AMD drivers and gave them a install. Restarted. Now everything is back to good as gold.

Still a but unsure of what to Trust, out of my whole build, my PSU / RAM and Video card were purchased used as I have been building this over the whole year with not alot of cash to work with.

The downfall now seems to be I'm getting a small bit of coil whine from the card now that i'm using the CX500. But if it can tie me over and be stable I guess I can budget a replacement.

I'll keep you guys in the loop.

Matt
