I have an ASUS PRIME H310M-K Motherboard, with an i3-8100 and 1x8gb DDR4 2400Mhz RAM. I recently bought an i7-9700f and 2x16gb Corsair Vengeance 2666Mhz LPX RAM. I placed the new RAM in, and the PC fans span up, the keyboard lit up, but the mouse did not, and nothing was displayed. I switched to the original RAM and got the same result. I then added the new CPU, as I noticed that the original CPU did not support the new RAM speed. However, the results are the same. I have been resetting the CMOS between every step. What can I do?
