KFA2 HOF 980ti that won't start, soldering?

[rul3s]

Hello mates,
I have a KFA2 Hall Of Fame 980ti that stopped booting, I suspect it might be something with the soldering or something but I want to discuss it with you before "jumping into the pool" and baking it to see what you think.

It was working perfectly and about a month ago it started doing something weird with the fans, which has 3.
When I started the pc and without load the side fans turned on and the middle one stayed still, but once in windows, the middle one would go from 0 to 100% several times until it stabilized, I blamed the latest drivers since it started happening the same day I updated the drivers.
Despite that, when I played, the fans acted normally and it didn't overheat or anything, max 80°.
A week ago I started having problems booting cold and also some crashes when I was in the middle of a game and had just started the pc, but I attributed it to the CPU overclock since I modified it shortly after, although now I've seen that it's not.
Yesterday, I was pretty pissed off about the issue since I left the cpu stock and it happened again, so I deduced that it had something to do with the graphics card, well, I took it all apart, cleaned it perfectly, all the fans spin well, thermal paste etc etc... I put it back together and now it doesn't boot at all, it makes a long beep and 2 short beeps and stays there.
I put a 970 I have from another pc and everything perfect at first.
I put the 980ti as a secondary and it detects it but says it has problems starting the device...

How do you see it? Any ideas what might be happening before baking it?
I've searched a bit on the internet and I haven't seen anything or anyone who has had anything similar happen... And the truth is that it's a big pain because at the price that graphics cards are going for to change it now and on top of that not being able to sell the previous one

Greetings mates!

A graphic piece, it really is a pain.

Before the oven thing, make sure the welds on the power connector and capacitors are good, if you need to replace any, you can do it yourself without any problem.

If you need to get into microsoldering, looking at the situation, I would consider taking it to a specialized center for reballing and microsoldering.

The reflow thing, you know it's today's bread and tomorrow's hunger: it usually lasts a few months and then, it's over.

I've tried everything already but nothing,

I've tried the bios switch from the back, in all positions, nothing, also disconnecting it.
I've tried another graphics card on my pc, and the 980ti on another pc, nothing.
I've connected it as secondary and windows detects it but can't enable it.
I've cleaned the entire pcb again and I don't see any visual damage.

If I don't see another solution I'll do a very light reflow with the oven to see if it clears up my doubts, in case it works, I would know that it's a soldering issue and I would take it to have a reballing done so that the solution would be more "permanent".

What levels have we reached eh? Before I would have simply changed the graphics card but at the price they are going, it just drives me crazy to pay almost 600€ for a 1070 damn.

I would have baked it already xD I had an 8800GTX that went through the oven 3 times before it finally died...

@krampak said in KFA2 HOF 980ti that won't boot, soldering?:

I would have already baked it xD I had an 8800GTX that went through the oven 3 times before it finally died...

What do you think killed it, the use or the oven? xD xD XD

CODE 62

I submitted an RMA to eVga for one of my 980Ti KP, it suddenly died, PCBs usually have quite a few failures due to design errors, so RMAs are commonplace, fortunately they offer a 3-year eVga warranty

Well, I'm updating here.

I did a first bake at 195º for 9 minutes and prové, the graph was still the same, long beep + 2 short beeps and setting it as secondary I couldn't initialize it and the GPU wasn't getting hot.

I did a second bake at 210º and then I started to hear some "fireworks" and when I opened the oven quickly I saw that the capacitors started to jump like crazy, theoretically the capacitors should have withstood more heat, but the plastic underneath blew up.

Now the last thing left for me is to change all the capacitors and try again but on an old PC because if I short circuit or something and mess up the board the anger is going to be huge...

How do you see it?

Was that a "very light reflow"? Damn.
