Can't solve a mystery overheating problem

I have a system problem I'm stumped with. My system is overheating and shutting down. At first I thought it was the SSD drive because I was getting disk errors, but now the system won't get past post.

My system is a i7-9770k, 32gb ddr3 g.skill ram, OCZ SSD drive, Geforce video card and a Corsair h100i liquid cooler and Asus Republic of Gamers Maximus Gene V mobo.

I just cleaned the thermal paste off the radiator and processor and applied more Arctic Silver but after booting, if I just sit in BIOS and watch the temps, it starts at 30°C and steadily climbs to ~90°C and shuts down. I've turned off all mobo performance options and all overclocking but it made no difference.

Is this the cooler flaking out?
 
A i7-9770k CPU, huh? And they went back to DDR3? 😉

You probably meant a 3770k?

How long have you used the h100i? Has it worked since then, and these issues are recent?

Have you tried hooking up the stock CPU cooler to see if it is the CPU that has an issue?
 
Sounds like the pump's dead on you AIO WC? Where is the pump plugged in to, and is it set appropriately in BIOS, if it's connected to a fan connector?
 
The piece you mount to your CPU is the pump/block. The radiator is the big thing you mount to the case and fans. I'm assuming you're applying the paste to the pump/block, not the radiator like you said. How quickly is it overheating? If it's rapidly over heating just while sitting in the BIOS, you don't have the pump/block mounted properly. There's enough copper to keep an idle, stock clocked 3770k from overheating for a decent amount of time. Checking your connections as VL said is important to be sure, but if you're over heating in minutes at idle, that's a mounting issue.
