Something wrong with my i5 7600k?

[adonis.marsas]

My system specs:
Intel core i5 6500
Kingston hyperX DDR4 16GB (two sticks)
MSI ARMOR GTX 1070 8GB
Corsair CX600 PSU
3x SATA HDD drives
MSI B150M bazooka motherboard

I've got a problem, today I just got a new intel core i5 7600k and wanted to swap out the i5 6500 that previously powered my PC. However after installing it and booting the PC up, the monitor showed nothing, the hard drives also showed no activity. Now I had prepared for the CPU swap, I updated the motherboard BIOS to version I.A0 which should allow compatability with 7th gen Intel CPU's plus when I swapped back to the i5 6500 everything worked perfectly again. I'm starting to think the 7600k CPU may be faulty, I took a close look at it and found this:

The yellow contact points on the CPU are somewhat darker and more bronze-like in the marked areas, I tried scrubbing it off thinking it was dirt, but it stayed on, on the old chip (i5 6500) there is nothing like that, the points are all shiny and clean. Could this be a sign of damage? Is this why it dosen't work? Help a guy out.

Quite possible. Try resetting CMOS after you put 7600 inside before booting. Also make sure heatsink is not overtightened (what cooler you have btw?). If nothing of the above helps, then most likely you got DoA CPU.

It could be. Try RMA-ing the CPU, if under warranty.

if you enter the bios you can see the bios version what does it say?

Did you flash this bios update?

I.A Release Date 2016-08-01 File Size 4.98 MB

If you did, it needs BIOS 1C or higher to support the I5 7600k

Core i5 Kabylake i5-7600K 100 3.8 1M 6M B0 91 HDGraphics630 1150MHz 7982vIC.zip

So put the old cpu back in and flash the IC or the latest BIOS which is IF

On MSI's site it clearly says that I.C is required to support new Intel CPUs; I.A is not enough. Do as Paul NZ suggested.

Well what do you know, it worked. I'm currently typing this on the PC that's running the chip right now. I think I know what happened, I was using MSI Live Update 6 to automatically update the BIOS to save myself the hassle of manually flashing the board, but the program for some reason thought that I.A0 was the latest BIOS version and installed it. Thanks for the help!

I'm still a bit concerned about the darker spots on the chip though, but since it's running fine I suppose it's no big deal right?

Just as long as its working thats the main thing!

Nobody should be scrubbing the contact parts of the CPU.
