Hello, today I received a brand new MSI B760 motherboard ddr5. I also bought a new 12700kf cpu. And installed both alongside 64gbs of corsair vengeance ram and a rtx 3080. I used an Intel heatsink cooler. The gpu revives power and turns on, so does the fans, but I do not receive any image on screen from gpu with hdmi plugged in. And the mouse received power but the keyboard does not. The cpu light is red as well. My assumption is that during the difficult cpu cooler installation I may have put to much pressure on the cpu, a few pins are bent.

Yup, bent pins would do that. If not too bent you can try to straighten them
 
Bent socket pins are caused by not dropping the processor in cleanly.
If you had to wiggle it a bit to get it seated, you likely caused bent socket pins.
This is considered as user error, and not rma worthy.
Remove the processor and look very carefully for bent pins.
Post a high res photo if you can.
Bent pins can be straightened with a needle.
If you can't, perhaps a jeweler can.

The stock cooler is unlikely to produce excessive pressure if done competently.
The 12700KF does not come with a cooler.
Exactly what cooler did you try to use?

Normal Intel cpu stock cooler
 
There are many varieties of Intel stock coolers.
The will fit different sockets and you need to have the correct match for your motherboard.
As a generality, the 12900K needs a cooler better than the stock cooler.
If it helps:
----------------how to mount the stock Intel cooler--------------

The stock Intel cooler can be tricky to install.
A poor installation will result in higher cpu temperatures.
If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient.

To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard.
The stock cooler will come with paste pre applied, it looks like three grey strips.
The 4 push pins should come in the proper position for installation, that is with the pins rotated in the opposite direction of the arrow,(clockwise)
and pulled up as far as they can go.
Take the time to play with the pushpin mechanism until you know how they work.
Orient the 4 pins so that they are exactly over the motherboard holes.
If one is out of place, you will damage the pins which are delicate.
Push down on a DIAGONAL pair of pins at the same time. Then the other pair.
When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place.
If you do them one at a time, you will not get the cooler on straight.
Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly.
This last step must be done, which is why the motherboard should be out of the case to do the job. Or you need a case with a opening that lets you see the pins.
It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly
unless you can verify that the pins are through the motherboard and locked.

If you should need to remove the cooler, first run the cpu to heat it up and soften the paste before shutting down and powering off the pc. That makes it easy to unstick the old cooler.
Turn the pins counter clockwise to unlock them.
You will need to clean off the old paste and reapply new if you ever take the cooler off.
Clean off old paste with alcohol and a lint free paper like a coffee filter.
Apply new paste sparingly. A small rice sized drop in the center will spread our under heat and pressure.

It is hard to use too little.
