Videocard no longer detected

[jjj807]

Hey everyone, so I'm helping out a friend who is having an issue suddenly with his 15 month old computer he put together. Starting today, his computer no longer provides a video output from his graphics card. The computer turns on fine and appears to boot and no mobo lights goes on. Display just says entering power save mode. When he switched the display to onboard graphics it works. When he goes to device manager he cannot find the graphics card, only the integrated one. He updated his bio, cleared cmos, and reseated his components. He put another videocard he had in the PCI express slot and it worked. Is his videocard likely dead?

Specs

Msi r7950 twin frozr
Asus z87 a
Haswell i5
Corsair 750 watt psu
8 gigs ddr3 ram( he tested one stick at a time)

did he pluged in the two 6 pins conector.is the monitor plug in the card

 

[jjj807]

Yes both power connections are plugged into the card. He also tried an hdmi cable instead of dvi same thing. I should note the graphics card fans do spin

 

[denis280]

did he try into another socket

 

[jjj807]

Yes he tried another PCI express port, same thing no luck. He put another graphics card in and he got video output from it. I'm guessing either card or mobo. He doesn't have another computer to test the videocard in

He doesn't have another computer to test the videocard in

Or can you try another gpu in is system

The only way is to test the video card is in another computer. And to check the motherboard is to put another known to be working video card in.

If he has a Power supply unit similar to thermaltake in which wires from the power supply can be removed then remove wire and reattach. Also you can test using a multimeter to make sure the power supply is really offering the proper amount of power to the graphics card.

Now assuming the power supply is fine then make sure the back side of the graphics card is properly locked down If not it can damage the motherboard.
If you have more than one PCI-E slot then try the other pci-e slot.

Also I ran into this 2 months ago. I was laughing and pissed off at the same time as the video cable went bad. Just buy a cheap video cable and see if that fixes things.

If the current vid cable works with on board video, then chances are, it is not the cable. Most vid cards have a couple of different output ports, eg., digital or VGA. Try the vga link - that would be a different cable. My sense is that after reading everything you've done, the card is hosed. The acid test would be to see what it does in a different PC.

 

[jjj807]

So He tried a different working gpu in the pc and it works fine, so I assume mobo is ok. He tried different cables with the videocard and it still won't video output.

The power supply is a reputable brand and powerful with plenty of amps on the 12v rails.

What would cause the gpu to just cut out one day? It's msi and less than 3 years old so he's under warranty. I told him to rma it

I have had two video cards fail on me, going back over 15 years of custom built PCs. It happens. Neither gave any warning signs that I recall. Interestingly, this was back when the high-end video cards ran extremely hot (probably due to the cooling they had back then).

I have encountered video cards in other machines that have failed, but they were dead when they got to me, so I don't know if there were warning signs.

Good troubleshooting by you and your friend. Any chance the warranty on it is longer than a year?

More than likely, overheating, overclocking issue. I have never been impressed by any MSI product. Their power phase design and component selection line up with their retail pricing.

It can be diagnosed but it takes time and professional diagnostic equipment and ability.
