A week ago, I opened my pc to clean the CPU cooler and its fan. After that when I plugged in the RAM, CPU Cooler and Graphics card I get "No Signal" from my monitor and No POST.
The fans of CPU cooler and graphics card spin and keep spinning until I switch it off at the UPS.

So far I have cleaned the sockets slots of RAM modules, graphics card and checked for bent pins on the CPU socket (there are none) and used another working Hyper Fury RAM.

The Motherboard Speaker gives three long beeps which after a pause continues again and again. The same behaviour is shown without the RAM module.

The Motherboard is ASRock model: H310CM-HDV/M.2 and BIOS is from American Megatrends. Processor is Intel Core 15-9400Fs, graphic card is GeForce GT 1030 and RAM is Corsair CMK8GX4M1E3200C16.
