Just installed a new Corsair CPU cooler and fans, connected all up as per instructions and powered up my pc but….no power

Any ideas or where to start looking?
 
Will get some pics on. Sorry really quick post before I popped out

As far I know all connected correctly and hooked up the icue link to a pci cable to a socket on the psu

I’ll check the basics when I’m back but I did wonder if I bent a pin on the cpu socket when I took the cpu off to clean the old thermal paste off as one looked different to the rest when I reseated it
 
Checked all the connections and can’t see anything missing. Everything I pulled out from the old fans was on one daisy chain with sata power cable connected to the psu so no risk of that cutting power to anything else

Power switch connections are in firmly

No lights on mobo either
 
Going to remove the cooler just to check the connections hidden behind it as a next step

Everything else on the wall socket is working too so it’s just the pc and have tried another plug with no change
 
Disconnected the icue link hub via pcie and tried, nothing

Tried disconnecting other items and removing memory with no joy either

It’s getting late in the day so ordered a new psu for AM delivery tomorrow. Will try that as next step, if that powers it up happy days. If not, back to drawing board
 
So tried a new PSU, connected everything up and no response still

I’ve tried the paper clip test on the psu that I read about this morning and the psu turns on with power and the fan spins.

Connections for the case power button are connected as they were when working and checked connected firmly

Some further messing about, managed to get power. Nothing different except for reseating the CPU for about the tenth time lol

I now get power, the motherboard LEDs light up and go through until stuck white on vga and green on boot

Have connected to a monitor and no output to display
 
Corsair 4000D Case
Asus B650-Plus WIFI
Ryzen 7 7800X 3D
Corsair RM750e
WD Black 2TB
Palit RTX 5080
TeamGroup 64GB DDR5 PC5-48000

All worked prior to me swapping out the fans to Corsair RX120 and Titan 240 RX cooler
Swapped out PSU to Corsair RM1000x as part of fault finding the issues

Tried reseating the RAM, GPU and M2

Motherboard has onboard but disabled it in the bios

Pics to follow
 
I’ve got the power sorted, reseated the cpu (already done several times) and got power

Powered up and motherboard lights lit up but no stuck on white vga output and green boot lights
Monitor shows no hdmi
 
Yeah it goes past those, goes past red for the cpu I think it was, amber for memory and then white for vga stays on whilst green for boot is lit up

It stays like that then with no video output before it shuts down. Presumably because I don’t have the cpu cooler on
