Pent Pins

[Just_Ged]

So I am trying to revive a ASUS ROG STRIX Z270H gaming motherboard. 3 pins were bent. I have been struggling to even have this thing to post. I purchased a BIOS speaker as im running out of ideas. non of the fans will run, it is an absolute dead nothingness from any LEDs other than the standby light next to my male fPannel pins and my rgb lighting. so the board is getting power, there is just no response from jumping it or using a switch.
There is one thing im never able to get a straight answer from and that is, there doesnt appear to be a jumper on my CMOS pins.
More ideas would be great

There should no jumper between the two Clear CMOS (labelled as CLRTC) pins on the motherboard.

Jumper in = clear CMOS.

Jumper out = normal operation.

 

If there are bent pins on the CPU socket, then that is the cause for why the system is not POSTing.

If the pins are bent, so they don't make proper contact with the metal contact pads on the bottom of the CPU, then it won't work.

Even a single bent CPU socket pin can stop the entire system from working.

 

I was helping a fiend troubleshoot his Z270 system a few months back.

The original Z270 motherboard was damaged, so he bought a new one...still wouldn't POST.

We ended up swapping CPU coolers, RAM, PSU, GPU, display cables (I have spare parts)...and FINALLY realized a single pin on the socket edge is bent out 180*.

Gave my friend a quick disclaimer...if pin breaks it can be RIP...straighten the pin without breaking it, and system POSTed and booted.

Yep. Pretty much what -rascal- said. Those pins must be important for some system process so it's not going to POST. Sometimes when you're lucky it's just a GRD, or redundant pin but that doesn't appear to be the case for you. If you get some sewing needles or thumb tacks you may be able to carefully bend them back. But, like mentioned above, if they snap you may as well kiss the board goodbye unless you know someone that's really good at micro-soldering. Even then it may not go well.

 

If the jumper isn't there for resetting CMOS anything conductive will do. A screw driver, a paperclip, etc. Alternatively just pulling the CMOS battery and putting it back in will cause the same effect.
