Broken GPU

[arendsoogg]

First of all, my PC specs:

Processor: Intel I5-4690k (not overclocked)

Cooler: Cooler master hyper 212 evo

Motherboard: MSI Z97S SLI Krait edition

RAM: 2x4 GB crucial ballistix sport 1600 Mhz

GPU: MSI R9 380 Gaming 4G

PSU: Cooler master G650M, 650 watt

2 hard drives and 1 SSD

 

So yesterday I was playing assetto corsa when my PC suddenly shut down. No BOSD or anything. Just, boom, pc off..

So I tried what everyone would do and power on the pc again. But it wouldn't turn on.

Then I went downstairs to watch some TV.

 

So I woke up this morning to look at my PC. I suspected the PSU was dead but that was not the case since my spare PC POST'ed while using that same PSU.

I didn't want to try the PSU from my spare PC since my motherboard has 8-pins for the CPU and the spare PSU only had 4-pins.

 

Then I disconnected everything from my motherboard and only connected the motherboard and CPU power and powered on my PC.

My fans started to blow and I was like, YES, it works.

But it only did for a second, powered down, powered up and repeated this cycle.

 

So then I asked my brother if I could borrow his PSU for a bit (he has the exact same one) and did the same thing, it started going through the power on, power down cycle again.

Then I tried clearing the CMOS by removing the battery on the motherboard for a minute and I connected my own PSU again.

Now my fans would spin for a bit longer, but the pc would power down after a few seconds, power on and stay on. But still not post, not even a beep from the motherboard speaker..

 

 

I suspect that somehow a part of my motherboard fried but I don't know why.. It could also be my CPU but I have no way of testing which is broken..

So then I put all my PC parts in their origional boxes and checked if I still have warranty on my motherboard and CPU which, thanks god, I still have. But only for a few months.

 

I'm thinking of RMA'ing my motherboard but I'm not 100% sure if it or my CPU (or both) are broken.

So if anyone has an idea of how to diagnose this I would like to hear your suggestions.

 

Thanks for taking the time to read this wall of text.

Remove the CPU, turn the system on and see if it can sustain operation. It won't POST, but see if it'll at least remain running.

You're going to have to borrow someone else's system. Maybe see what happens without a CPU installed.

Out of those 2 I'd say it's most likely the mobo. Just because non-overclocked CPU's generally don't fail.

 

 

If it's not the RAM or GPU or another part causing problems....

I did try that and I think it kept running, though I'm not 100% sure so will have to check it again.

Does it mean the CPU is faulty/dead if it keeps running?

I don't know anyone with a LGA 1150 socket so that's probably not an option.

And I ruled out the ram and gpu because it didn't do anything without those either..

The CPU could be faulty, the socket could be, or even a component around the socket could be faulty.

Aha, it could be a few different things, as always with hardware.. 

 

I'm going to try running without the CPU asap.

I just tried running the system with only the CPU and motherboard power and the speaker connected, no CPU installed and no monitor connected.

It just kept running without shutting down itself

Can you put that CPU into another build? Or can you put another CPU into your current build? Assuming the two are compatible.

Unfortunatly not. I don't have another motherboard or CPU compatible with the LGA 1150 socket

Do you see any visible damage around the CPU socket(sides, and rear behind the board), and within the socket itself? Shorting pins, weird looking capacitors, etc. 

[Ashleyyyy]

that sounds to me like a ram problem, i've had that behavior when i had a defective ram stick. can you try some other ram? or reseat what's already in it?

I'll take another look at it

I removed the ram and powered on the system but the motherboard didn't even make a sound (speaker was connected).

shouldn't it bleep when it doesn't detect any ram?

So I found some filthy 'I don't know what it is' on the back of the motherboard under the sata connectors.

 

Spoiler

 

I also found the same stuff in really tiny bits on the back of the mobo under what I believe is the chipset (next to the CPU with a headsink on it)

 

Spoiler

It also looks like these two tiny orange things aren't fully orange anymore whereas in the middle picture you can see on that is fully orange..

Those orange components may ba polyfuses. They are reset with time to rest. Let it sit for a day or two.

The stuff you're seeing on the back of the board might be flux.

Ok, so I decided to assamble the essentials of my pc again to day and it worked!

So then I started building my pc again and checking if it worked every time I added a component.

And right at the last piece, the video card, my system didn't power on when clicking the power on button. I removed the pci-e power cables from the GPU and my pc powered on just fine again.

I also tried the other pci-e power cable since my PSU has 2 but that also didn't work.

 

I'm clueless of what's broken (or not).

 

I'm probably going to try my GPU in my other pc after lunch alhough I need to rip out my PSU again.

 

 

I'll keep this thread updated

[arendsoogg]

I tried my GPU with my PSU in my other pc and it didn't power on.

So my last test is going to be powering on my system with my video card in it with my brothers PSU so I can be sure mine isn't broken.

[arendsoogg]

I tested with my brothers PSU and my system didn't power on so my guess is a broken video card.

 

However, I don't see why my system won't power on with a broken video card in it..

 

My final conclusion: GPU is broken, time for an RMA

 

fun fact: this is my second broken GPU in 2 years. Last time my sapphire R9 280 broke

[arendsoogg]

So I RMA'd the card. They tested it and agreed that my gpu was broken. Got a msi RX 480 gaming x 4g as a replacement. Pc works fine as far as I can tell right now.

Thanks to everyone who replied for taking the time.
