7970/280X Crash issue

[dboyd]

Hi All,

I am coming up on the three year anniversary of my computer build, and that means everything needs to come crashing down.

For the past 4 months, I have been sent my video card, the Gigabyte 7970, in for 2 RMAs, only to have them not work properly, crashing with gray lines and then booting to this screen after that and then proceeding to stop booting (http://imgur.com/a/zfwCv).

Today, i got back the Gigabyte 280X as a refurbished replacement for my Gigabyte 7970. I am again running into similar issues, making this the potential 4th RMA experience. I was able to play dota 2 fine when I didn't stress the card at all, having everything on pretty low settings; however, once I put everything to highest quality, I get this happening: http://imgur.com/a/AjraQ

Is there something I am missing here? Could it be another component, like the Seasonic M12II 620W not providing enough power (despite the suggestion being 600 W), or is Gigabyte not handling the repair of their units correctly? When I use my friend's older nvidia card (GTX 460), everything works fine, so to me that rules out the motherboard and perhaps the powersupply.

Any help would be appreciated.

it does sound odd that you have now a 280x with the same problem. It could be a power supply or motherboard issue, the gtx460 is a less power hungry card thus not showing the issue perhaps. Do you have another power supply you could try? Another question, have you reinstalled drivers since this problem happened, maybe a corrupt AMD driver. If you have a spare hdd or something try a clean install of windows and amd driver on it.

Sadly, I don't have another power supply to try.

Yes, I have reinstalled the drivers since this happened. In fact, I have to since the only other available card I have is an the old nvidia.

To make this even more fun, my 3 year warranty runs out December 27th, so I have very little time to figure this out. If you think it worthwhile to purchase another PSU, I can give that a shot.

So I have replaced the PSU with a Cool Master V750. Still the same issue arises. Any suggestions?
