Question PC starts fine and then lags horribly

[johnparkerallen]

The other day I turned my PC off as normal, and today when I go to start it everything starts okay but then it lags so horribly I can't open anything, and my cursor freezes as well. Usually Corsair link sets my mouse/keyboard colour a couple seconds after booting but that's not happening either.

Specs:
MSI B360 Gaming+
Intel i7-8700K
Gigabyte 2070s
16GB of Corsair Vengeance RAM (~4 years old)

Yesterday ny computer started acting up, it boots fine but laga horribly as soon as I get to the desktop. I was troubkeshooting the ram, and it does the same thing with one of the two sticks, but doesn't even boot with just the second stick. Time for new RAM?
