Possible loose cable on GPU causing screen problems and BSOD

The display on my laptop's behaving very iratically when in gaming graphics mode. If I tilt the screen back or flex it it gets worse. This doesn't happen with the intel graphics.

I've taken the keyboard out and unplugged and plugged in the cables connecting to the keyboard from the display but still the same problem.

Are there any other connections I can look at checking? It's very odd that it does this only with the discrete graphics.

Thanks in advance

 

I wonder if moving the screen it is flexing the whole casing slightly. If the GPU has a poor connection try reseating it (unless you tried that) . Better still, since you have removed it start the machine up on the iGPU just to make sure it does not happen.

Good luck.

 

Hi, I dont want to reseat the gpu until last resort as the screw holes are very worn. What is igpu?

 

The iGPU (Integrated) is the intel graphics you mentioned in your main post.

If the screen is fine on iGPU, then it's most likely not the screen or cable and is probably the dedicated GPU. It could be faulty, and I'm willing to bet it is failing. Run system diagnostics through the boot options, and call technical support as soon as possible.

If you dropped your system, it may be dislodged. You can try reseating it.

 

Get a good fitting screwdriver. If the heads are worn then it's been out possibly a few times and further points to a GPU card issue. The iGPU is not a separate component but is part of the CPU (Go intel, way to destroy the competition in the low to midrange laptop market!). Starting the machine with the card out will just use the iGPU.

 

Ran full diagnostics and passed all the tests..

I think I've just fried my igpu . I switched the connection over to the 3d one and now bios won't detect it.

 

Thanks for your help guys!

Integrated graphics seems to be ok again. Going to ring tech support tomorrow as they're closed today.

 

When you say 'switch over to the 3D how did you do that? It does sound like it but since it's part of the CPU and moving the panel changes things I'd still be looking for a poor connection somewhere. Maybe pop the CPU or it's a complete tear-down sit .

Sorry, this is confusing me, not something that happens often I guess...

 

The problem with the integrated GPU happened after I connected the display cable to the 3D port next to the standard port. I know was stupid but was fed up by that point.

I've now reseated the main GPU and the screen was perfect for 5 mins then when black and shut down. Went black when I logged back in also. The display on TV is still fine though.

I didn;t know what you meant by reseating, I though you just meant do a repaste job.

Anyway, I'm going to leave it a couple of days for the paste to dry a bit

 

Ah, I see now, you managed to introduce a new problem . I didn't think it was possible to plug into the other display port without a cable change

All I meant by reseating was to remove the whole GPU/heatsink assembly, clean the contacts and put it back. What happens if you start it up with the GPU card removed altogether? I would think it will run just fine.

I have seen the black screen issue before and it has often been simply a driver version issue, but when my 675m went bad it did that also and a replacement by dell fixed it all.

If you repasted it then it could even be that you did not do it correctly? The paste only gets poorer as it dries out, usually over a period longer than one year. So I don't think a wait is going to help . It could be overheating now if this is the case? You'd need to monitor that with something like MSIAfterburner. Grabbing at straws here

 

Hi, I know right, why do they use the same ribbon cable for 3d and non-3d screens.

The display works fine with the onboard graphics (for now lol). So there's no need to remove the gpu as I can still use the laptop for non-gaming tasks. I can still game with it if I hook it up to the tv which I do anyway. I wont be able to play civ5 or total war if the screens messed up though.

Different prob with screen now. It no longer displays weird colours now it flickers on and off and in between where there are horizontal streaky lines

I've done repaste before btw and improved the gpu performance so don't think that's it. Maybe the 0.5mm thermal pads I replaced old ones with are more likely the cause than my paste job.

Its all very strange though. Why it works on my tv but not the laptop display?

 

It's looking very like it's time to look at your GPU replacement options. The 6990m was the top AMD gpu for the R3 I believe. Going for a better card is going to have some compromise and needs research from people that have done this. The top NV was the 580m and from my experiences with it I can't recommend that. The most popular upgrade I have seen for the R3 is the 680m but I believe the AMD 79xxx (can't remember the number!) is popular.

Warranty will eventually get you a replacement card after all their tests if that's an option?

 

The warranty ran out a while ago Thinking of buying a new laptop instead as I want a better cpu also; a thinner laptop too so I can work with it on my lap. I really like tge look of the aorus x7 but its a lot of mulah!

 

oh well, if you take out the GPU at least it will all work and you might be surprised how well the Intel handles many older games and a lot of the indie stuff . You can then at least sell a working machine with the GPU missing (declared!) .

Good luck in your search, check out the communities for support feedback from and about the OEM. One of the big deciders for me in a high-spec laptop!

 

Thanks mate
