Is my graphics card dead?

[Krispenwah]

Hello everyone. I need help figuring out what's happened to my computer. One day while I was gaming, the screen suddenly teared before completely going black. I could not do anything afterwards so I turned off the computer. When I tried to turn it back on, however, I couldn't manage to get it working again. My computer and the fans start, and there is a single short mobo beep, so I don't think the mobo is dead but there is no display. The keyboard and mouse also don't seem to be working. I've tried using one of several sticks of ram and trying each in each slot to no avail. I've tried plugging it in to a separate monitor with mn luck. I've also reset the CMOS. My PSU is new so I don't think it's gone bad yet, though it's a possibility . I really don't know what could be the problem here other than the graphics card. Unfortunately I don't have an extra computer to test it with. Any advice would be appreciated.

My PC consists of a Gigabyte R9 290x Windforce, an FX-6300 cooled by an H80i, an ASUS M5A97 R2.0 motherboard, 16gb (4x4) Corsair Vengeance ram, and an EVGA
SuperNOVA 850 G2. I got my video card second-hand off ebay about a year ago, so it might have already been used a lot, but it seemed to be working fine.

EDIT: I did notice that some of my fans were running a bit louder the past few days. Whether it was the cooler, the card's fans, or the chasis fan I couldn't really tell. It doesn't run so loud anymore, however. I noticed one of the GPU's fans is running slower than the others, so I'm not sure if that could have contributed.

Can you borrow a videocard to test in your computer? That motherboard has no onboard graphics, so you'll need a card to test it. Since you have a liquid cooler, a leak is a possibility. Also, were you overclocking? That might be a cause as well. Don't assume the PSU is good. It might be new but if there was a short then how new it is doesn't matter.

I do not unfortunately have another graphics card on me nor do I know anyone I can borrow one from right now. I neither overclocked the card nor the processor. How would I check for a leak if it was my cooler? I can't really see any liquid anywhere. I know assuming is probably bad in this case. It's just that having just replaced my power supply I don't like thinking I have to replace it again.

The only good way to find out if it's an issue with the video card is to test the card in another known good system. Otherwise all you can do is replace every other component till you have nothing left to test, or just replace the card now and see how things run.
