I have been having this kind of issue like two years, at least. My GPU was expensive (700€), and I thought the issue must be in somewhere else. So, I did not send it to RMA nor have I bought a new one, because when it works okay, it is still good. Anyway, few years back I bought very nice new components and I spent almost 5000€ on this PC and f..! I bought the first digital PSU (corsair ax860i), with 10 years of warranty, and it cost like 500e too. I was so proud from my new shining PC…
Until suddenly it began to just cut off the power totally random. It might shut down three times during a film, or not once in a month … and it did not have anything to do with usage, sometimes it happened at night and so on. So, I googled about that PSU, and noticed that people are telling the same thing. Green light when testing it, gives the right voltage from the rails, etc. And they had sent it to RMA, only to be weeks without computer and get new one with same issues. While that was going on, this GPU issue was going on at the same time. I thought it must be that PSU causing the screen go black randomly when surfing the web or watching movies etc.
First the picture freeze on screens and TV, but the sound goes on. Cursor and everything freeze, image becomes still-image and about ~5 seconds after that, all the screens go black and turn back on, leaving sometimes some websites broken (some parts black) until refreshing. Every time after that I get that “AMD crash handler” message, that the driver had crashed, and would I like to send feedback. I have, like, 50 times given that feedback properly, until I realized nobody care. It is VERY annoying, if you would like to lay on the sofa, with someone even, and then you have to get up just when it is nice. Just to wait for the black screen to come and go, and put the film back on. Today it has been wild, It has been doing that all the time … I am so full of it.
I have changed my motherboard, I have changed my SSD, I have changed my PSU twice…! And what ever slot at motherboard I would stick it, what ever you might be doing on PC, it just keeps happening totally random. Year after year, so that my exhausting aggression against it has changed to anxious despair, and I have given up all the gaming and so.
It hurts my brain that I pay thousands and thousands, and I am lucky if I get to listen one good song some day my eyes closed, before it happens. It is like it was sinister action, the more comfortable you are somewhere or so, then this happens mostly. But then again, it may not happen in weeks … It is totally irrelevant of what I do, where to plug the GPU, and which cable goes to which port, and so on. Nothing helps. (Or maybe some people could be writing a driver which would not crash. :D). Some error code it always has with Radeon DLL's and with ntdll.dll.
Anyway, the point after the whining and telling how much that issue ruins things is that probably that new PSU won't help, because someone was thinking it. Worst thing is, that when you get yourself a new PSU, and suddenly it won't crash in weeks, and you feel joy, like “it is over!”, and then suddenly… again. I have also tried those different gen PCIe slots, and changing all the possible settings from bios, and also trying so many drivers and plans and programs. It bothers me, because I would like to know WHY that happens. And not just that “These expensive cards sometimes are like that and one should just buy new and ignore it”. I can't. But one thing is for sure, it has caused a LOT of sadness, ruined so many moments, etc. It has scarred me for life. So if after all these years someone really knows what to do, like some wrong driver or something physical which can be modified inside the card (I have training for that kind of work), please tell me. I stumbled on this and saw that I am not alone with this, that warms my heart.
Thank you. Phew.
