So it started with my computer getting surges and shutting down while I was gaming, I read somewhere that my 24 pin connected could be loose. So I checked it and it was out a bit, so I pushed it back in (forgetting to ground myself) and then tried to start up my pc... It didn't turn on. After hours of messing with stuff and trying many different configs I gave up and went to bed. I have a much older machine and I have just finished testing my powersupply, Graphics card and Ram on this older machine and it all seems to be running just fine.

My problem is that I have no clue how to test my CPU as my older system has a older chip slot. My motherboard is the H170-PLUS D3 from Asus and I don't know if my motherboard is fried or the CPU.

I have a strong feeling it's the motherboard that I broke when I didn't ground myself but I don't want to drop £100+ on a new motherboard to find out that the CPU is the problem here.

Here's a good troubleshooting thread for when you think you've messed something up

Ultimately if everything is connected right and getting power (which is not a given), I think you're supposed to get some beeps if your cpu is fried but not your mobo. If you're not getting any beeps, no post, then yes it might be your motherboard and it also could be both your motherboard and your cpu. I don't really know of 100% reliable way to tell other than to get something that fits on that board or another board that fits that cpu. Since your other machine is incompatible (you sure this board won't take the chip from your older computer?), you need to take it...

You can try this first, to clear the CMOS by the jumper, after that boot the PC. If it will be the same, then try next.

Use onboard iGPU, one stick RAM, no boot device. After clear the CMOS by the jumper, boot the PC. Now you will 1) the PC can boot, but you get no boot device error, that means the CPU/MB are fine. 2) the PC will not boot, that means either the CPU or MB has problem. If you don't have the compatible parts ( other cpu or MB), and nobody will know until you go to local PC shop or your friend ask for help. Or check the cpu to see there is any physical damage, like the burn mark. If the cpu is fine, I think your MB may has problem.
