Hello, and thank you in advance for your help!
Today my pc turned off while I was in the middle of a Skype conversation, so nothing too demanding. The screen turned black and stood like that for a cople seconds until I shut it down manually.
My GPU is an Nvidia 1050 TI, my psu is a 6 years old 400 watt 80+ bronze psu and my CPU is an Intel I5 3570.
At first, when I tried turning it on, it wouldn't post. The fans started spinning but everything would turn off in a couple seconds only to try booting again and fail.
Tried changing the RAM (i had a couple old chips laying around so i decided to give it a go), but it didn't work.
After a couple more tires, it eventually turned on but it still didn't post. The GPU, CPU anf case fans were all spinning, but no image in my monitor. Decided using another adapter and even trying an older GPU I had laying around, but to no avail.
I tried removing the GPU alltogether and it finally posted. The only time i got it to post is when I used the integrated GPU.
Another thing that I feel it's worth mentioning is that, for the last couple months, whenever I was gaming, the screen would randomly go black for 3-4 seconds and then return back to normal. Always thought of it as a GPU issue, but it might be more than that.
Thank you a lot and feel free to ask me anything.
 
If two GPUs didn't make it work, then it has to be something else. I think it may be problem with motherboard PCIe slot. If you have another one, try putting GPU there and see if it works. A test of another PSU would not hurt either, but I doubt it would be a PSU problem.
