New GPU causes garbled graphics

Hi,

Today I installed a Geforce GT 710 GPU into an old computer (Athlon 64 X2, 4GB DDR2, Windows 10). Initially, setup was smooth. I installed the Nvidia drivers and I was good to go. However, after a reboot, I experienced severely garbled graphics (see photo); even the windows boot screen was looking horrible. After testing, I have found that every other boot has garbled graphics, with half of the boots being normal. So far I have tried swapping cables and uninstalling the driver (back to Windows basic display driver). Neither of these have worked. What should I do next?

Thanks,

Ben

Hi everyone,

I think that I have found 'a solution'! I installed another copy of Windows 10 on the computer and tried disabling 'fast start-up'. Problem solved! I tested rebooting a few times and had now further problems. After re-enabling fast start-up, the issue returned. Obviously I proceeded to leave it disabled! Very strange that this should cause any problems; almost as if it wasn't loading the driver with fast start-up enabled.

Thanks again for all the responses,

Ben

Thanks for the advice SgtScream!

The BIOS does not have any issues. I have since re-installed Windows 10, which presented me with a 'non-garbled' desktop. However, upon restart, the issue persists. The more I test the PC, the fewer times it boots with correct graphics. Using the Nvidia driver or the Windows driver makes no difference. Also, the computer has started randomly rebooting after BSODs, see this image.

I am beginning to think that I have a broke GPU!

Thanks for the help.

Hi,

I cannot replicate the issue in safe mode, but as the issue is intermittent, I'm not sure if this is just a coincidence. As the computer has a completely new install of Windows and new drivers, would this suggest a hardware issue?

Thanks again!

Generally speaking, though others have disputed this, if you can boot into safe mode and the problem isn't present it suggests a driver problem. (Safe mode uses the basic drivers for a PC to function.) I think the addition worry is you mentioning you experienced the issue with basic drivers but not in safe mode.

Which driver did you try installing? It may be worthwhile trying a different driver.

While this is a very basic thing, try reseating the graphics card. (I had one come loose once for no reason I can think of, so you never know.) Depending on your motherboard it may be worthwhile trying the graphics card in another PCIe slot (or another PC) to check if it works without problems.

Hi,

Sorry for the really long delay, I have a busy week!

So far I have tried reseating the graphics card, with no success. The graphics card is PCIe x8, in an x16 slot, would this cause any issues?

I will look at drivers and testing the card later, probably next week. Sorry for the wait. I have a feeling that I will end up RMAing the card.

Thanks,

Ben
