Have you tried taking the graphics card out and connecting the monitor to the motherboard output?

Also check with motherboard website specs. Maybe you need to update BIOS with old CPU before you can use the new one.

I put the i3 back and it boots to Error Recovery. And when i select "start windows normally" it boots perfectly ...
Ok so everything does work fine when you boot up with the old CPU.

Heres the thing, the CPU is actually pretty simple when it comes to configuration, there is none. its one of those things that should just drop in and go.

Where did you get this new CPU?

Major errors like that tell me that there is something very wrong with it. There aren't any settings you should need to change in the BIOS. And you reset the BIOS anyway and it still didn't work. This is a problem.

IMO that CPU is bad.

So it was new in the Retail box? And the BIOS detects it properly?

Before sticking a fork in it, I would reinstall Windows. If you don't have a disc you can download a Win 10 Media Creation Tool that allows you to make a USB you can install Windows 10 from, then try your Windows 7 product key (it should work).

If that crashes then I'm back to my original theory of it being defective.
 
I presume your motherboard is the sabretooth Z97 mark 2.
Both the i3-4150 and I5-4690 are both supported at the 0801 bios level.

One usual cause for failure is a bad insertion of a cpu which bends the socket pins.
In this case, reinstalling the I3 successfully disproved that possibility.
I think your 4690 is bad, I have heard stories of fake processors on amazon which might be the situation here.
I would return the 4690 as defective.
And... you have an overclocking capable motherboard so I would suggest a i5-4690K as a much better upgrade.
