Ex58-ud5 wont post

[BruceY30]

HELLO I have the following

Gigabyte EX58-UD5 rev1
Cpu i7 970, 3.20GHZ/ 12M/4.80/08
SLBVF 3031A794
Video MSI ARMOR RADEON RX 570 8GB GDDR5
RAM Crucial CT51272BA1067 2sticks 4GB each 512MX72 DDR3
PSU THERMALTAKE TOUGHPOWER PS-TDP 1,000 watt 80plus
hard drive Crucial BX500 120GB 3D NAND SATA SSD

Now that's over, my problem is it wont post, monitor gets no signal. No beeps. the led code number was 68 (PM Init). Not knowing I checked ram installed properly by removing and re-installing. Same result. Next I inspected cpu. Just to see it too installed right. Everything here looked good, clean off old paste, applied new paste. reinstalled coolmaster . NOW what it does when I plug in and turn on, all the fans spin (2 on video card, one in front of case, one on top of PSU, and the cool master fan) Just when fans begin it shuts down, off for 2-3 seconds then turns back on by itself, then shuts down again. It keeps repeating on-off-on-off until I pull the plug. This behavior started AFTER I removed and reinstalled those parts. Before it would just run, no beeps, and no signal to monitor. The 68 code I was getting was before I started my troubleshooting. This is a new build, all new parts and Im sick over it.

Checked CPU socket?

In the manual there is no 68 post code, in this post (quick post codes) 68 is for video init.

Try CPU and one memory stick no other parts, see what error code you get.

How is it "all new parts" when all parts are 10 years old?

"how is it all new when parts 10 years old"

Maybe a technical slip of the tongue my bad

Motherboard still in shrink wrap.
Ram store bought
hard drive store bought
Video card used very little less than month. Know it worked in friends pc
PSU store bought

Removed one of the ram sticks, tried with just 1 same, moved to other slot ok 'd for single stick ram, same on-off-on-off

I noticed some spots of discoloration, notice few spots in picture. upon close inspection they look like smudges, no matter is those spots, just smudges

That CPU is not supported until bios F13 or so - one of the last bios versions. So check your bios version and see if that is your problem.

Not supported? How do I check bios version if can’t post to bios/ cmos? On package? We’re you able to see “ smudges” on picture I hope shows ?

I can see 3 darker areas there, more concerned with the socket than the CPU contacts, need a good clear macro, with digicam if you have one.
Best take it all out and bench test it.
Video card may work, but not compatible with this old board, have anything older less exotic card?
Will be difficult to know what BIOS version you have if it does not boot, maybe a pc lab with right equipment can read it off the board. Or if you feel like spending few more bucks you can try look for i7 920 which should work on any BIOS version.

Gfx card is PCX express 3.. board has only 1/2 suport… (try basic pci express card for post..) ?

Lol I used to be a Pc parts hoarder up till about 5 years ago. I would of had 2-3 pci vid cards I could try. But I did some serous purging. Why hold onto old technology my thinking. I have to look deeper into cpu comparablity issue with current bios version. BUT. I will keep in mind your advice. Thank you

I removed the cooling pump, CPU and cleaned the heat grease off surfaces. Upon closer examination of cpu socket, see what I see I hadn't seen this before, but could have missed it. forum only "allowed" 1 picture/post. I will try to post other closeup picture

[BruceY30]

here is closeup the one contact is NOT in same alignment as the rest
