horizontal lines display corruption

[ishan34]

My VGA card is GTX 760, n suddenly i got a problem with displaying. it displays horizontal lines at the beginning of the start my PC. i will attach the Images. i just test this card with different machines and the same issue came.

without drivers it shows horizontal lines in the display , and machine is not struck or reflash display. but when i install drivers it try to load the drivers and the display corruption came with different pattern . and it stuck my PC ones in a while, i will attach the images of that as well.

i try reinstall VGA bios, but it didn't fix the issue.

there is some thing i found that surprise me. in my friend's machine. if i try to backup VGA bio file Using TechPowerUp GPU-Z software it flash the screen 2,3 times and fix the issue. my VGA is back. i play games with 100+ fps there is no issue what so ever. i really don't understand what is going on. but if i restart my PC the problem comes again. and also i checked this method in my PC but its not working for me with my PC. it re-flash the screen and just came with same issue (in addition my friend's machine, he got NVIDIA drivers installed for his PC)

so there is no way that my GPU is broken like its not a hardware fail in my opinion. its working so good. i don't know where the issue is. is there something else i can do to fix this ?

1. Have you tried a other or new vga cable
2. have you tried using the integrated graphics
3. have you tried to reinstall the graphics driver
4. have you tried to rollback the vga driver
5. have you tried another graphics card
Maybe there's something wrong with the graphics card or the pci express?

Most likely an issue with the port on the video card.

None of those are valid since he also mentioned that he tested this on another computer & still got the same issue.

Looks like VRAM corruption to me / dying card.

i tested all , even VGA card ports different monitors.

but the card is working, i play mafia 2 full graphics with 100+ fps without no issues.(in the method i showed).

To me it looks exactly like a hardware issue, could be VRAM.
The only thing you can try, is take apart the GPU, clean the whole thing with IPA, replace thermal pads and thermal paste, and see if it helps. If not - it's probably time for a new card.
Repairing this thing would be inadvisable - the card is too old, and procedure isn't cheap (assuming you can even find someone to do it)

but the card is working, i play mafia 2 full graphics with 100+ fps without no issues.(in the method i showed).

Having to reflash BIOS after each reboot and having intermittent artifacts and driver crashes - that isn't "working".
I used to have a 770 which only had the "Driver stopped responding" problem, but worked flawlessly if I increased timeout. Few months later it still died. You can only delay the inevitable.

 

[ishan34]

other graphics card?

yes, other card working , Intel onboard graphics working, tested with 3 machines. same issue, but one machine can fix the problem in the way i mentioned. and also i tested 3/4 times it works 100% after i do that backup bios thing.

I experienced this with my HD 7850 years ago. It was the sign of dying. Mine showed the the sign only if it hit 80C+, so I just undervolting it, set the T limit to 70C and kept using it.
Worked fine but It completely died later, no display, no fan, after sometime of use probably 4-5 weeks.

 

[delshay]

It's clearly a VRAM fault or you have a bad contact somewhere. Possible HR (bad solder contact) one one of the DRAM Chip.

yes it could be, but i am curious because card is working 100% after access bios. so i might be thinking its a software fail or bug when it comes to displaying. but it could be actually dying. problem only fix with drivers, if i just uninstall or disable the card from device manager problem comes again. its not working with my machine at all. strange thing.

that make sense. and if it is , can we fix this with a repair ?

Even if it's repairable, as @silentbogo noted, it's not a good a solution. Card is too old, fixing a mid-ranged card of such level is costly & not worth it. Better use the money elsewhere such as a better & newer mid-range GPU.

maybe the OP could try the baking method?

I don't know why people get angry over this recommendation when the OP literally has nothing to lose.

As long as he's aware he may lose the card, he could try it. It's not like he has much going for him now.

 

[FreedomEclipse]

Its a risk worth baking

You thought you could get away with that, didn't you? Well now you are in trouble, mister. I've reported you to the punstapo.

 

[FreedomEclipse]

Also heres a decent enough guide to give you some idea if you dont know how to do it.

 

[silentbogo]

If it's VRAM failure, baking will only make it worse and potentially kill a perfectly working GPU in the process.
If it's a GPU, it'll only be a temporary solution. As I said before, just delaying the inevitable.
He can at least sell a semi-working 760 for a few buck, while he can't sell a totally dead one (especially if it gets damaged in the oven).
As an electronics repair tech and a hardware junkie, I can tell you that a dead untouched card is worth more for me than a working baked one. You can't sell it cause it's a ticking bomb (assuming you are a honest person), and you can't use it for parts cause after one uncontrolled heat cycle any component may become a ticking bomb(even chokes on VRM).
If you hear stories about baking that fixed the card permanently - it's mostly lies. Either it lived long enough to be sold as a working one, or it worked for a couple of months and went back into the oven, or it started having issues later and a person was simply ashamed to clarify that this fix didn't actually work, after writing dozens of happy posts about his success. The only kinda-exceptions to this rule are NVidia Tesla and Fermi or AMD's 5000 & 6000 series, which had this issue more frequently than later cards, but after reflowing or reballing would occasionally not just survive, but work for a year or two afterwards.

Also heres a decent enough guide to give you some idea if you dont know how to do it.

Even if you do it, that's not how you do it.
1) lead-free solder melts at higher temps, so there's no reflow or anything going on there. Just thermal stress between GPU die and substrate jiggles it a bit in place for a chance of temporary effect.
2) No flux - risk of BGA balls sticking together or detaching from the board completely after cooldown (that concerns both vRAM and GPU).
3) If you yank that card out of the oven right away - it's too much thermal stress. You can irreversibly kill it. If he did it at proper temperature(230-250C), he'd also lose half of his components all over the kitchen floor, misalign a GPU or warp a PCB. It has to cool down gradually.

I don't know who or where user(s) state putting card(s) in oven came from, so I'm going to be clear on this.

NO, you can't put a "fully populated PCB" in an oven. There are too many sensitive components on the card that will not survive 180c & you need to get to around 215c for the solder to melt. Some plastic will not survive these hot temperature.
They need to be removed or shielded from the extreme heat first.

If the OP put the card in an oven, it's almost certain the card will come out in a worst state & is most likely to come out fully not working. Under extreme heat in an oven, some of the components on the back side may possibly fall off & drop to the bottom of the oven. Clearly you don't want this to happen unless you are collecting spare parts.

I have an oven here & I only use it for BGA re-balling nothing else. If I want spare parts the quick way, then yes, stick a fully populated card in an oven, bring it up to temperature, then pull the card out while still extremely hot & tap it on the table.

Stand down man. Baking has been used as a temporary alternative fix for almost a decade now. The success to failure rate is 50/50 so you have nothing to lose by trying.

I'm taking "solder reflow" not "heat shock". The solder manufactures use start melting at around 215c+ & I can't see this changing anytime soon. If anyone out there reach 215c+ then some plastic header will have discolouration, deformation.

Sticking any fully populated card in an oven (without shielding), regardless of what type of card it is, is not how proper repairs are done. The OP card is almost working. Sticking it in an oven increases the risk of card going completely dead & non repairable.

 

[bobbybluz]

Others have posted likely causes and I have one to add. Years ago XFX released a batch of GPU's with very bad capacitors. I had three of them and all exhibited the same identical issues. I recapped them and they lasted for years until I sold them. Check for bulging caps.

There is a sorta how-to somewhere here on the forums, maybe even a video its been a couple years since last i seen it.
