Yesterday I installed 2 new sticks of RAM and used my computer for a few hours with no problems and the new RAM was working. Today, not even the fans will spin and my computer won't boot up. I've tried taking out the new RAM, and nothing changes. I've checked the PSU connections but I don't see anything wrong.

Help would be greatly appreciated.

Computer specs:

Motherboard - MSI Z370-A Pro
Old RAM - Patriot DDR4 2400mhz
New RAM - Corsair Vengeance LPX DDR4 2400mhz (both pairs are 2 sticks of 4gb)
PSU - Thermaltake Smart M 650w

All of these parts were working fine yesterday, I don't know what has changed to cause the computer to not boot.
