PC won't boot up with GPU

[lukas.luby60]

Hey guys!

First off, I'm rather noobish when it comes to PCs, I guess I know basics but that's it. Here is my build from 2 months ago:

FX-6300

8GB DDR3 RAM

RX 470

EVGA SuperNova 550 G2

Mobo: Gigabyte 970a-ud3p

So here is the thing. Two months ago, I came back from work and, as usual, booted my PC on right after. I was browsing youtube a bit when it happened. PC went off instantly, just like that. I was trying to boot it back on, without any success. I took the GPU and tried it in my bros PC, fans were not spinning, it was dead. I don't know what else was faulty tho, I couldn't boot it even without the GPU.

Fast forward to yesterday. I was playing Fornite with friends in late hours, when same thing happened. PC went off, instantly, again. I tried to boot it up but, no success. I have quite a lot of lights in PC, from motherboard and fans, none of them even blinked. I was desperate. Here is my brand new build.

I5 - 8400

4x Patriot 4GB DDR4 2133Mhz

Seasonic 550w Focus Plus

Gigabyte Z370 AORUS Gaming 3

RX 470 (supposedly new one)

I tried to remove the battery to reset CMOS, plugged the power cables on/off, didn't help. I was desperate, so I tried to remove GPU and boot it on without it. And voila! It worked. I can play fornite (yay) on the integrated intel HD card, but sadly on on my dedicated GPU. It seems like it's dead, again.

Here is other strange stuff. When I boot up the PC, the RPM of fans changes at least 3 times till it gets to windows, which didn't happen before. Also, after restarting the PC, fans went on really high RPMS, and stayed like that for whole time.

My question is, what could have happened? Is it possible that GPU damaged other components?

Thanks for the answers in advance.

When looking at your build, the only thing that I notice is weird and odd, is your choice of PSU. The wattage of your PSU is strangely low and I'm surprised your computer is running on it. With the components you have attached, u should have at least a 600-watt PSU, this being the bare minimum. If you want to be safe take a 650 watt. There are may in a good price range that can do the job.

Well, I thought I'm actually way over the needed wattage? I used this site http://www.coolermaster.com/power-supply-calculator/ and upon entering every component I have, it says the load wattage is 299 wats.

I know I know, this maybe me off and surely isn't precise, but still, the I5 8400 is 65w and the rx470 is 160w at full load.
There is no way I'm going over 400 wats overall, so I think I'm safe there.

Yeah, I looked at some psu calculators and you're right. Maybe the psu is just dead or faulty. Otherwise, try going into your bios and then see the settings for your gpu, whether or not it recognizes it as a pcie card.

 

[lukas.luby60]

Well, it was working for 2 months straight. What I think happened is that I got short circuited GPU, and PSU has prevention against such things happening, that's why it doesn't want to boot.

That's my amateur guess.

I can boot up the PC without dedicated rx 470 GPU on my Intel HD integrated card, but once I put rx 470 in it, it just doesn't want to boot up.

If someone had a similar problem, please tell me about it. I would like to know more about this or how to prevent this in future.

I personally own a rx 470 and I haven't had such a problem before. Your theory is plausible though.

Where did you get the 470 from? Warranty replacement? Or ebay?

reset your CMOS by jumper, while power is unplugged from the wall

check your temperatures of your CPU with coretemp

update the BIOS within BIOS

Thank you for your answer.

I already reset CMOS. Seems like GPU is fucked. To mention, it did the same exact thing 2 months ago, now it did again.

Temperatures were all fine, going anywhere from 70 - 76°C. Same for my I5 8400, never exceeding past 68°C.

I bought the GPU from local store, alza, as brand new model.

I'm just afraid that all of this could potentially damage other parts without me knowing.
