Chosen Solution

Hello I upgraded my motherboard and CPU and after a long time trying to fit everything nicely in the case, I turned it on and we’ll…this! Tried both the MOBO and gpu ports, still nothing, along with a lot of noise from the AIO, but that’s something I assume I can change in the bios. Already tried changing the Ram around, checked the CPU if it sits correctly, gpu spins at start but then stops. Removed the Gpu, and tried without it, still no. Checked cables, all fine. I haven’t tried turning it on and pressing the Bios buttons, but my keyboard is a Bluetooth one, and even though I hooked it up with a type c cable, the MOBO won’t recognize it. Please tell me there’s something simple I did wrong and that I didn’t turn my PC into a hunk of scrap. Specs: MOBO:cvn B660i Cpu: i5 12490f Ram: 32gb 3600 corsair sticks Psu: Cooler Master 650w gold Gpu:Asus gtx3060

Hi @olly_ck, The CPU is not shown in the supported CPU list for the motherboard but given that there are higher spec’ed CPUs it should be OK. Try connecting a system speaker (supplier example only)to the motherboard speaker header pins (see #14 p.28 of the manual I think) and check for any beep error codes when starting the PC. If there are any beeps (normally for most PCs a single short beep is heard if the PC passes POST (Power On Self Test), Colorful PC doesn’t have any information regarding beep error codes, so you may have to contact them and ask what they mean.
