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:

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!

That is not a *new* part.

I wouldn't think it damaged the CPU, but no way to know until you try it with a non-screwed up motherboard.
And there is no way I'd plug a CPU into that motherboard ever again.

Yup they bet pins same thing happened to me when i was cleaning my PC i bent a few pins [7 pins bent and one of them was badly bent]
BUT i managed to make it work by using a MAGNIFYING GLASS and the tip of a 0.7 mm MECHANICAL PENCIL!!! IT TOOK 8 tries foR ME to get it working !!
BUT IN YOUR CASE YOU HAVE SOME BADLY BENT PINS I SUGGEST YOU RETURN IT OR TRY TO BEND AS MANY PINS AS YOU CAN AND TRY TO MAKE IT WORK!

That is a common technique. But you also run the risk of breaking one off. Yes, we used to do this (aircraft connectors), and yes, I've seen some pins break off.
No way to tell until it is too late...:)

Motherboard replaced with an 'actual' new one - Now runs like a charm.

Thanks for the input!
