Has it been doing that with any frequency at other times? Or just that game?

The stuttering and USB-esque noises? Those only happened on Path of Exile, and only in the last two days. It used to crash a lot when playing Warframe, but there was no sign of when it was going to do it and it stopped doing it so much eventually, which made it seem like it was just one of the game's updates messing with it rather than the card itself. I've had it a little over a year and it's run Warframe fine for most of that time.

Well, if it's doing that mostly when playing games, then it's either not getting enough power (PSU is bad or not strong enough for the card), the driver is bad, or there's some incompatibility in which it's not running well with the computer at sustained high speeds (Which is sometimes due to poor registry settings set by the manufacturers which assume no hangs at all, often resulting in a timeout response from the card.) If a piece of hardware crashes enough times within a given time frame, windows will often disable it to protect your hardware, assuming it's not blue-screening and a critical piece of hardware the OS needs to function.

Most motherboards and video cards these days come with voltage and temperature regulating software, which is highly recommended. It'll often slow the card by a few FPS, but is typically much more stable. If it's the registry setting that's doing it, there's a way to adjust those to allow the card more time to process tougher loads before skipping to a timeout response. Disconnecting and reconnecting is the most common response to a timeout request, or a power failure, but it can definitely still be caused by heat damage, faulty drivers or equipment, or a incompatibility though.

Next question would probably be how old the rest of you computer is, and if you overclock or use any voltage software with your computer and card at all.

The computer is just over a year old, and the only thing I ever did with MSI Afterburner was actually apply some temporary specific intentional underclockings to try to resolve the Warframe crashes a few months ago, though it didn't help so I stopped using it. Anyhow, the Warframe crashes basically stopped eventually anyhow. It shouldn't be a power issue though, when this thing got built we made sure it would have plenty of power. x)

I don't think it's drivers though, unless they could actually keep the card from functioning at all. Presently I can't really access the affected PC at all because....no screen to look at means I can't see anything to fix it if it's possible without ripping the card out. What I find odd is that it came on so suddenly though, hence my fears the card itself suddenly died.

If you have a CD with your video card driver on it, you could try booting from that to reinstall the driver. It's a pain not having a motherboard with on-board video for when video cards fail. There's some registry entries that can be changed that may help too, though It only works on windows 7 on down, windows 10 removed the ability to edit the registry and/or has a different setup me thinks.

If the card is under warranty though, you could just switch it, but if the same issues continue after than, then it's definitely a compatibility issue.

I do have that CD somewhere, so long as that works without me seeing anything.

And the weird thing is, I could have sworn the motherboard does have video...but I may have just thought it did back when I removed the GTX's drivers trying to fix the Warframe issues and had a super zoomed in low res screen while doing that. I dop have 7, luckily. I'd hate to not be able to mess with registry stuff, that can solve so many problems if you know what you're tinkering with!

No, most video cards have basic internal drivers that will display a low res until the proper drivers are installed, that low res you saw was most likely still coming from the video card, though it's possible you do have on-board video and its disabled in the BIOS, but if you're not getting any signal at all, you can't even see that.

Here's a question, if you turn the computer on, do you eventually hear the OS sounds? Or does it not get that far? Some motherboards won't continue without a video card or keyboard, but if it DOES reach the OS there might be something you can do.

Oh yeah, there's OS sounds. That just makes it even more terrible, knowing everything's there...and I can't see it. x)

If that's the case, I can walk you through a couple things. Gemme a sec to pull up the list

I'll have to write down said list though, since all the peripherals and the monitor will need to be moved over...unless that's not important, anyway.

1. Press the windows key. (Usually between control and ALT keys on the left side.)
2. Type in device manager and hit enter.
3. Press tab then press arrow down 3 times.
4. Press shift and F10 together then press arrow key down 1 time then hit enter.

(Your computer should now be scanning for hardware changes, if the device is functional and recieving power, the computer should now detect and list it, wait a 5 to 10 seconds for this before continuing.)

5. Press right arrow key 1 time, then down arrow key 1 time (There should only be 1 entry assuming it's there and you don't have multiple cards or on-board video.)

6. Press shift and F10 together, then arrow key down 1 time, then press enter.
7. Wait a second or two, then press enter again.

(Your computer should now be attempting to reinstall the driver, this can take between 5 to 30 minute at the most, if nothing happen or you don't hear any device disconnect, then reconnect, you missed a key, or the video card isn't being detected, otherwise, it should come back to life and you should be able to install a proper driver from the manufactures website.)

(If you do here a disconnect and reconnect sound, let it keep working for a few minutes, the signal should come back, but if it doesn't after up to 30 minutes, the video card could be disabled, if this is the case repeat steps up to step 6, but press down arrow key 2 times before pressing enter, you should be on the enable disable tab, not sure if the device manager will still be up after installing the driver so you may have to close out entirely before repeating the steps up to this.)

(If it still doesn't come back at this point, then the card is definitely dead and should be replaced.)

Oh also, this is on windows 7. I don't know if these shortcut keys will work the same on any other version of windows.

Well it theoretically works based upon doing the steps until stopping before the driver part on XP, so I may as well give it a shot on the borked PC. x)

Okay so...pretty sure the card is dead. It might be showing up in thatl ist, because for a good while I could hear the fan revving up to max and then cutting back down and sudden intervals in odd manners, but at the end of it all...still no video. The enable/disable step didn't give me fan revving, so I redid it to presumable re-enable the card, will probably try swapping it to another slot tomorrow, or trying my roommate's spare card pair.

Ouch man, that sucks >.< is there any manufacturer guarantee/service you can do with it?

Three year warranty, luckily, but if I have to go that route I will be missing all of my gaming for a while D:

I'd check into anything you can do warranty-wise. Man, that blows a ton. D: If you want, I've still got my dual 770s that work just fine that we can replace it with.

I still have 576 days worth of warranty to leverage with EVGA. I am probably going to have to RMA it. I hope to god it's the card and not something else. We could always temporarily replace it though, at least after seeing if there's another slot to move it to in order to determine if the card is bad or the slot it's in.

Fair enough, you may wanna check in on that if we can't fix it this weekend.
