Hi all, new here and sadly expericing a problem I have not seen before. I bought a new PC (spec at the bottom of the post) in late 2021 which has hardly been used since purchase due to work reasons/not being in the house. It has worked and been capable of being on for 10+hours, but like just mentioned it hasn't been used daily/reguarly, probably only 100 hours since purchase.

This week I have turned the PC on for the first time in weeks. It booted up, logged me in and everything seemed normal. Then I noticed my PC monitor said nothing was detected and seconds after, the PC would turn off. It's like it shut down rather than the power was pulled and it instantly turned off. I will power on the PC and it will start to boot, 30-40seconds later the same will happen, just turn off. Last night this happened 3x in a row, then the 4th time it loaded up fully and I was able to start using the PC for around 5 minutes before the same thing happens. Why would it behave in this way, does anyone have any ideas or suggestions?

It's under warranty and I can take it in for checks, but am i being silly here, is there something i am missing?

The PC was plugged into an adapter but i plugged directly into a wall socket and the same occurs.

I can post a video to display the issue if allowed, however i won't be able to till this evening at earliest.

Thanks all in advance for replies

Might be a failing psu but it could be many things.

You could try a known working psu to see if that helps and just send the faulty psu in for RMA but if you don’t have those resources, RMA it.
 
You need to contact support and get them to help you out. Mobo or PSU are most likely faulty but it needs checking out properly.
 
I would call out the psu. kolink aren't that great. i remember back in the day when ocuk used ezcool tornado psus for all custom and pre built pcs. they where utter poop and ended up damaging my pc but thankfully ocuk repalce all and got me a different psu. corsair gs800 at the time and still working 12 years later, all be it in a low 250watt system:)
 
Sounds symptomatic of a PSU issue, could certainly be something else but given it's a Kolink i'd put my money on it being that.
 
There’s a known issue with some RTX cards and EDID.

NVIDIA fixes a hidden bug in some RTX 30s, does it affect your GPU?

Sometimes the launches may not be what the user has in mind, and that is that the pressure right now for the big brands to come first and higher can take its toll on their products. NVIDIA has been slow to react to AMD’s bet, where again Lisa Su’s team beat them in different segments …
