[SOLVED] PC started beeping after after installing new RAM ?

[Imashelha]

So I installed new RAM on my pc, booted it up and it started beeping, I’m very new to this so don’t know much. I haven’t changed anything
Pc specs:
MB: ASUS H110M-k
Old RAM : 8GB 2Rx8 PC4-2400T-UB1-11
New RAM: 2x8GB 1Rx8 PC4-2666V-UA2
I have an i5-7400 cpu, can’t get exact specs as I can’t turn on my pc anymore since even when I plug old ram in, it still beeps and doesn’t load up. Help would be much appreciated

Check that you didn't accidentally knock a fan or fan header loose/off .
You didnt install the ram in backwards at any point did you?

Check fans and all cable connections everything seems in place, I’m almost certain I installed RAM correctly and I double checked that too.

nvm I’m absolutely brain dead and the HHD got unplugged whilst I was cleaning the fans, big thanks for the help mate
