Intro
New build for friend with all new* components: Power loop which seems to power all components/fans for about 1-5 seconds before powering down; beginning the loop again. No display, no flash screen or bios seems to be accessible in this short period of time.
*Motherboard arrived from Amazon late with:
-No sealing on box,
-Anti-Static bag UNSEALED,
-Pen marks in user manual circling front header panel.
History: Yesterday's Troubleshooting
Have tried various components in my PC (which work fine):
-All 4 modules of RAM,
-Power Supply Unit,
-Haven't attempted to use GPU yet,
-CPU in my PC fairly late last night - It had the same Power cycle/loop issue on my PC with my SSD and HDD plugged in (I'm not sure if PC's get 'confused' by new CPU's/By all means I could of sat the CPU wrong too as it was getting dark and late). I haven't attempted CPU troubleshooting before but I have successfully built many PC's in an Apprentice job role.
Also was greeted with 'Flashing Underscore' screen when I tried to boot my PC with original CPU. Had to disconnect/reconnect SDD/HDD after a system repair then restore before it booted properly again.
Have tried various methods to resolve:
-Triple checked (being modest) by rebuilding from scratch:
Motherboard seating onto Standoffs (case only has 1),
CPU & HS seating onto Motherboard.
-Booting with ONLY: 8-pin, 24-pin, CPU, 1 x RAM module in DIMM slot 1,
-Various sticks of RAM in DIMM slot 1 defined by the User Manual (furthest from CPU), as well as checking they were seated properly,
-Reset BIOS by removing CMOS battery, shorting jumper pins (defined by user manual) and then using power button before reconnecting Power Supply.
-Following 'shortstuff_mt' troubleshooting guide to the T*; as well as various other topics across the internet.
*Have yet to 'Breadboard' as I do not feel comfortable till I get some feedback on picture (see below) and also due to lacking ESD measures that I would be more comfortable with. I also currently lack a speaker.
Today's Troubleshooting
So today I rebuilt the System from scratch again. When re-seating the CPU, in the light, I noticed some imperfections on the Motherboard CPU pins - Please take a look at the pictures below and tell me if this is likely to be the culprit:
Motherboard CPU pins:
I commented to my friend before I even began building it was a very strange condition for the Motherboard to arrive in (not sealed & pen marks in user manual).
In my experience of System building I haven't seen pins like this before and I am slightly concerned that there is a possibly they have caused damage to the CPU.
Is this possible? Maybe why it wouldn't then boot in my PC last night? I cannot see any imperfection but here is a picture of its latest condition:

Motherboard: ASUS P8Z68 DELUXE/GEN3
CPU: Intel i5 -2500K
RAM: G.SKILL Ripjaws X 16GB (4x4GB)
PSU: Novatech 850W
IN SHORT
-Am I missing anything here?
-Is Motherboard likely issue behind boot loop?
-Possibility that CPU is now damaged from Motherboard CPU pins?
I believe that covers all the basis, please feel free to contact me if not - Thank you for taking the time to read, I'm hoping to get my friend happily gaming away sooner rather then later!
Cheers!
