GPU disapeared for a couple of days.

Hey guys, I had a problem with my graphics card the other day which has seemingly resolved itself, but I was wondering if anyone could shed some light on what happened?

A few days ago i get back from a trip turn on my desktop and get no signal on either of my monitors. I check all my cables, open up the case and confirm that the fan is spinning so it was presumably getting power but still nothing on the screen. So I plugged a screen into the motherboards VGA output, and finally my windows desktop shows up on the screen.

I had a look at the device manager and the GPU wasn't listed anywhere. So at this point a assumed that I had a dead GPU and the system had reverted back to the Mobo's Integrated graphics.

I figured that i would just keep running with integrated until i could afford a new GPU in a few weeks but a couple of days later i started getting no signal again and plugged my monitor back into the GPU outputs on the off-chance that something would happen, and all of a sudden its working again and the integrated graphics output had switched itself back off.

So yeah, I have no real issue at the moment apart from suspecting that my graphics card could be on the way out but I was wondering if anyone could shed some light on what went wrong?

I'll get back to you later tonight, I typed up a wrong message and need to fix it.

UPDATE:

Ok, so for your case, there are a few possible reasons why. One of them is poor connction between the motherboard PCIe lane and the graphics card PCIe connector. Make sure that is clean.

Another possible reason is aging power supply. This depends on how old your PSU is and PSU do become weaker over time and this is more likely the issue IF you bought a power supply that just met the minimum power requirements needed by your computer though I doubt that is the case unless you have a really old PSU.

How long have you had that graphics card and other parts of the computer?

You can also try testing the GPU in another computer, possibly a friends or co worker or any computer really that has a PCIe lane and a decent PSU. Let us know how that goes.

Another possible reason is that your graphics card is posibly becoming defective or the motherboard PCIe lane is becoming defective. Since it will be really hard to tell just by looking at it, you will need to check it by testing the card in other motherboards and testing different cards in your own motherboard, if you have a few of each of those hardware components.

Maybe your GPU is loose and needed to be tighten.
