Question Problems after putting parts together

[lucascobino]

So I've just put my system together

• I5 11600k
• Asus PRIME Z590-P WIFI
• RTX 3060
• 3x 8gb DDR4

My RAM sticks are a bit different frequency:

• 1x 2666 (1333MHZ)
• 1x 2998 (1499MHZ)
• 1x 2400 (1200MHZ)

I've been experiencing the following. If I turn the PC off/reset, whenever I turn it on again it's a black screen. I need then to press the power button for a few secs and do a hard turn off so it will give me a bios error. Only after that I'm able to enter bios and boot to windows.
After booting I basicallydo all need o do. I can work and game (Path of Exile and Elden Ring) without problems.

Has anyone ever experienced this? How do I fix it?

Mixing RAM is never a good idea, they should be bought in matched sets.

Try with just one stick of RAM in the proper slot according to the manual and see if it will post.
