RX480 Losing Signal to Monitor

Hey y'all. I'm turning to you because nobody else can help me. I have a Sapphire RX480 8GB card that has been in the computer for about a year now with no problem. Recently I noticed the card was getting hot and the fans were getting loud so I had a tech expert check it out and fix the fans. Everything was fine for a few days until the card would either lose connection to the monitor (connected via DisplayPort) or completely crash the PC. Just today I was able to launch and play Fortnite with no issue. I intentionally left the PC running when I left the house for an hour and the monitor was off on standby again. I've changed the cable from the power supply and I've tried the second slot for DisplayPort with no luck. Anyone know what I am doing wrong or what is going on? The card is lit up right now but it won't even let me boot without crashing if it's plugged in. Oh, and the temperatures were low, even under load.

 

Specs: 

 

i7-3770K

Asus z77 pro-v

1tb Seagate hard drive

16gb DDR3 Corsair Vengeance memory 2133 mhz

Corsair h60 (2018)

 

Thank you in advance.

That's probably a dead gpu. I had the same issue - r9 270x. So I baked it (google the instructions for that) and it worked for two months, then started dying again - baked, worked for 2 weeks, died again, baked, 2 days, again... And it's the worst time possible - I was planning to wait untill nvidia next gen cards and buy either 1060 cheap or 1160 if it's worth it.

The card was running perfectly fine just yesterday. Today I can’t even boot because the monitor signal is not getting signal. Is there a way to test for which part is faulty? Mentioning this again, but the card would only cut off under load - could this be a psu issue?

You could try using the iGPU to make sure it's a GPU issue. Different PCIe slots could also be an option. You might also want to boot windows into safe mode and run DDU to uninstall the GPU drivers and reinstall them.

Possible but I'm more inclined to believe it's the GPU

Make sure to quote me or tag me when responding to me, or I might not know you replied! Examples:

Interested in computer architecture? Still in middle or high school? P.M. me!

 

I love computer hardware and feel free to ask me anything about that (or phones). I especially like SSDs. But please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.
