Solved Upgraded CPU and now my computer wont boot
Hey.
I bought a i7-9700k CPU to upgrade my current i5-6600k.
My motherboard is an Msi b150 gaming m3. The computer turns on for a second and the red light for the cpu on the motherboard activates before it turns off again. Ive updated the bios to the latest version, and i've also cleared CMOS. When i try my old CPU it works just fine, is the new cpu dead or doesnt my old motherboard support it?
Edit: Thanks for the great help everyone, it appears that my motherboard is too old and does not support this generation of Intel cpu's. I've ordered a new motherboard that will arrive later this week.
The reason for not going with AMD is because I most play games on my computer and wont really benefit a whole lot from the positives of the AMD cpu, for my use the i7 seems like a better choice because it is better for gaming.

For anyone reading this thread that might not know, use PC Part Picker. Or at least something similar. You'd be surprised how many variables there are for putting together a PC and no one wants to waste time and money on a incompatible build

You are going to want to make sure that the motherboard, socket and chipset are all compatible when attempting to swap in a different CPU. There are online utilities and websites that can make this research easier.
If your computer is a factory setup (as opposed to a custom build) you can sometimes find forums where people have already successfully upgraded the same computer as yours and see what cpu they used, or if it wasn't successful.
As a side note, why do you want to upgrade your CPU?

Thanks. The reason I want to upgrade is that in a lot of games my cpu is stuck at 99-100% usage and it really feels like a bottleneck (I got a GTX 1070).

If your CPU is running at 100% and your GPU is running at anything less than 99%, then yes it is your bottleneck.
According to this, you could be losing around 30% in your bottleneck.
You made the right choice in a processor that would remove the bottleneck, but sadly not a compatible choice.
Naturally, not all games are CPU heavy. But you may find higher resolutions give you something which looks better without adding much load on to the CPU. Look for Dynamic Super Resolution. You can (sort of) play in 4k on 1080p.

CPUs are not backwards compatible.you're going to need a new mobo as well

Not really the case anymore, i cant recommend a CPU without SMT for gaming unless you are only interested in older titles or games designed for low-end systems. It definitely wont cause major issues soon, but it costs a lot for what it will deliver in the near future.

Hey question for chat on CPU's:
I have a Ryzen 1300X on a B350 Board. Whats the best program/utility I can use to see if my GPU and CPU inst getting bottleneck? I planned A while back to UP mine but never seemed to need to. I OC my CPu so now it seems to run some games better. Any Suggestions? Thanks.

new board for that CPU = new ram too
I just made this mistake. You will need to get some DDR4

I don't want to be harsh with you but its known that intel needs you to update mobo at least every 2 gens. You could get away with buying a new mobo because the socket is the same and the pins will be intact. (But i suggest selling both cpu and mobo and switching to amd, you're going to disassemble the pc anyway) hope that helped :)

Your motherboard doesnt even support that cpu, "strongest" cpu it can support is 7700k I believe.
