| 1275040 | 2012-05-13 09:23:00 | Hello Recently my computer has hung, either at the end of a youtube video (not every one), or before BIOS, there are other times but those have been the most common. I'm pretty sure it's caused from the GPU(s) since the screen cuts off (but maintains connection) and the fans start going full bore until you turn it off. I've got 2 ATI HD 6870s and it happens regardless of having crossfire on or off. I've tried disconnecting the second GPUs cables from the PSU and the crossfire connector (but not taking the GPU out) that still happens though so they're both running again. Interestingly this hasn't happened in games yet, it could be that the main GPU has had it. Any suggestions? |

| 1275041 | 2012-05-13 09:27:00 | Do you oc your system? Mabye try running with crossfire off but with the other gpu. Do you know the temps? | stratex5 (16685) | ||
| 1275042 | 2012-05-13 09:31:00 | Disable hardware acceleration. Under the flash options. It worked here (www.sapphireforum.com) | Speedy Gonzales (78) | ||
| 1275043 | 2012-05-13 09:48:00 | No I don't OC my system at all, it's running with crossfire off right now and it still does it just as much as with crossfire on (same with only having one GPU connected to the PC) I only know the temps from rebooting after it crashes but they're quite normal, nothing crazy. I've disabled hardware acceleration now, would that fix it only with flash objects though? I've also had problems before the BIOS which is why I thought it would be hardware related, and one today while I was doing an assignment on word (yay for autosaves ^_^) It doesn't BSOD, but the GPU fans just go 100% and black screen while keeping the connection to the PC Thanks for all the help, hopefully it won't do this anymore! |

| 1275044 | 2012-05-13 21:50:00 | Rebooting to check the temperature is no good, the temp drops immediately when the load is removed. If you suspect the graphics cards are the problem try furmark, it loads the GPU to 100% and graphs the temperature so it's a pretty good test, although games would stress it more than youtube so not sure there. Remove one of them and just try each on it's own for a while to see if it's one or the other, physically remove though don't just disconnect. Also maybe try turning off at the wall for 30 seconds, hardware occasionally does weird things until powered down completely for a bit (long shot but not hard to try). I personally gave up on SLI and won't try dual cards again in a hurry, just caused me more hassles than it's worth and didn't speed up all my games. |

| 1275045 | 2012-05-14 02:24:00 | Thanks dugimodo The GPUs run at a normal temperature when they aren't playing on games so I don't think it's an overheating issue When I disconnected the cables to the second GPU I had to turn the wall power off so it's been off for long enough recently. I'll try removing one later on, but for now I have uni and I should really be spending most of my time doing uni work,rather than worrying about the GPU problem but Speedy's advice has stopped the problems so far, but in saying that the problem isn't frequent outside of youtube videos so if there's a problem within the week then I'll have to keep looking at it but for now it's working fine. Yeah next time around I won't get SLI/Crossifre since it only seems to give marginal improvements and gives you a lot of problems (either Crossfire or Eyefinity for me) |

| 1275046 | 2012-05-15 03:34:00 | You seem to have so many problems with that system. You only just got it to work ok. |

| 1275047 | 2012-05-15 03:43:00 | It's been fine for ages, months I would think, and as you know I haven't changed it in all that time. Either late today or tomorrow I'll open up my PC and take out the primary GPU and put the second one in it's place, having only one in the system Since the last post it's done this resuming from sleep, as well as shortly after loading the desktop, so I'm pretty sure it's one of those GPUs. |

| 1275048 | 2012-05-15 09:38:00 | Ok so now I've taken the first GPU out with the other one still in the second GPU slot, still have the problem and to try and make things even simpler, I've disconnected my second screen so I only have one running now, in terms of what's connected to the PC it's very very basic, really only things most people need (mouse, keyboard, speakers etc) I was thinking it's a hardware problem but if I've disconnected the second GPUs cables before, and now I've completely removed the first one, what could it be? |

| 1275049 | 2012-05-15 09:42:00 | Remove both and run the onboard graphics if you can. If this works then its a gpu issue or else its probibly a mobo issue. Even if it works it could still be a mobo issue if the slots dont work. | stratex5 (16685) | ||
