I just put in the i9 a few days ago and when I started the pc it did what it’s doing in the video so i tried another cooler from one of my older motherboards and to my surprise it worked but temps were in the high 90s so thinking it was the cooler so yesterday I got the deepcool AK620 Cooler but it did the same as before. As a last hope I took pc downstairs to try on tv there and it booted up fine and temps were low but when I restarted it, it went back what it was doing so I’ve no idea what the issue is. others have said I need more fans which I’m looking to get but clearly the pc works otherwise it wouldn’t have come on at all. I did update the bios too and again it booted up until I restarted. I’ve contacted a Pc repair shop who are gonna ring me hopefully tomorrow. Has anyone had same issue?
 
Can you describe what happens in the video, or post it to YouTube? I have no idea what I'm clicking, so I'd rather not :o

You hear the fans whirring and after the few seconds a light on the card flashes and it just repeats with fans not stopping.

Ahh, I see.

From the symptoms you described (inconsistent boot, boots in different orientation, excessive temps), it seems like there's an issue with the mounting pressure, perhaps that it is uneven, or excessive and that's causing the PC to have boot problems, which if I'm correct is not uncommon.

The other possibility I can think of (which relates to the restart issues) is that you might have unstable memory (e.g. not stable with XMP enabled, maybe because the voltage isn't high enough) and it is leading to boot failure, though this is far less common with DDR4 than DDR5.

Would the Thermalright Contact Frame solve this?

I think the frame is designed to apply more even pressure to the IHS/CPU, since the ILM only clamps in the middle, so my guess would be that if there's a big mounting problem with the cooler leading to boot problems or very high temps, then the frame alone won't fix it? If the frames aren't installed properly they can actually add their own issues too.

850w psu
What model?
Would also double check all psu connections
To the gpu
More fans aren't going to fix that

PSU is Corsair. pc repair guy coming Saturday to try fix it and if he can’t he’ll take it to shop and bring it back next work. Hopefully it’s something that can be fixed at home.

Corsair doesn't really help without model number
They don't make their own psus
Some have been great
But they have had some poor units too
I know it's booted a few times
So may muddy the waters
But does look like may be psu related possibly
Hopefully if he's a decent repair guy
He will bring a psu to test that option
No integrated graphics on that cpu is there?
But out of interest I would disconnect the power
To the gpu
And see if it stays on even though
You won't be able to see anything

Think this is the Model number CP-9020200-UK. I actually tried it without PSU connected to GPU but still did same apparently 12900 does have integraged graphics.
 
Decent psu then got one here
Thought the k didn't have igpu but the kf did
Hard to keep track of all these cpus
Tetras may be on the right track
If its not psu

Does that motherboard have diagnostic boot leds?
Would look it up but just off out for dinner
