PSU trouble

[Deleted member 211755]

@Chrispy_ Yeah, probably bad contact on the motherboard. Yes, it's good to have documentation of the events. I usually write stuff down after I fix somebodies PC.
Already helped me a few times. Thanks for the support

@eidairaman1 I did not notice any dust in it, but you may as well be right. It probably was a bad contact, although I cannot understand why reseating the graphics card first two times didn't help.
I did notice that at one end of the PCIe x16 slot (side where you mount the screw) was higher then the one where you lock it down because of the way my case was designed.
I really had to push it a little stronger and screw it tighter so it could fit.
That's why I think it was bad contact.
My regular date for cleaning in near so I will take out the GPU and clean the PCIe slot with a can of compressed air just in case it was a little dust left in there.

It was seated crooked, that will cause cards to not initiate on an agp system even

I tend to use silicone oil (sparingly) on contacts, although it is not good for high current switches as the sparks produce glass.

@eidairaman1 It looks like it, yes. And the card is pretty heavy. If it was screwed a bit loose last time I cleaned my PC maybe gravity took it out of the slot over time
@Andy Shiekh I always use a can of compressed air as it somehow is the most safest way to clean. It is a great way to get that dust off the components.
Now I have 6 ventilators with the new Artic ones so more dust will be present. I will have to clean it more regularly now then ever before.

Is it possible to use another connector on PSU for your GPU?

Never mind, I didn’t read all the comments.

I find canned 'air' rather expensive, and use a DataVac instead

For future reference, I have an idea what might have caused the issue, as I had a very similar problem with my 3080 Ventus just a few days ago. MSI, and I'm sure other manufacturers do it too, uses horrible, low quality thermal pads - I think they're called oil pads by some people, because they get oily over time. My card had actual oil droplets going into the PCI-e slot - I use a testbench so it stands vertically on the motherboard - which caused all kinds of weird behavior, including fans ramping to 100%, clocks dropping to near idle and such. I took it out, cleaned what I could reach with isopropyl alcohol, it's now working perfectly fine and new thermal pads are in the mail. Simply reseating the card before I noticed the oil didn't work, I guess the oil might have created some sort of a thin film on the contacts.

I use an air compressor, never killed anything

Actually that was probably not the problem as silicone oil is used on electric contacts and the electricity quantum tunnels across a thin film.

Interesting. GPUs are so expensive, I don't understand why they use that approach other then to cut down the manufacturing price...
I will check if something similar happened to my PC. If it did, should be clear to see.
At first I thought all of this was caused by a bad PSU as it started breaking down at the same time as the GPU started acting all wierd
but when I received a new one from the repairs the GPU continued to ramp up fans and drop performance so I thought the GPU itself was bad.
I tried a lot of things before sending it to repairs but nothing helped and after I got it back I did those 6 things and I think seating the graphics card more firmly and screwing it in more tightly helped.

I know it maybe seems quite a stretch, but could it be a bad HDMI cable was responsible? I replaced it too.
Maybe I could connect the old one. Try to reproduce the problem. But I like it how it works now so maybe leave it alone haha

That's a good way to clean your PC if it is strong enough air compressor.
I have one too, but it is so weak it can't get off any dust so I buy a can of compressed air.
Could look into a more durable way of cleaning as those cans don't last long.

@Andy Shiekh That DataVec could be the way to go

I have had one of these for over 10 years. It's loud but it works well.

And to others that do not own one, it's NOT a vacuum.
