Pc won’t post intel i5 11400f

[BALTDJUR]

My pc suddenly would post. CPU and dram lights are. Fans and rgb is on so I took out cpu and found that my cooler had come with two plastic covers and I had only removed one but the pc worked for 2 years without issues and the temps were fairly stable. I removed cover reapplied thermal paste but no change. pc won’t even give me any sound signals for errors. How do I diagnose this I assume rn it’s either motherboard or cpu

You do know that your processor does not have graphics, correct?

Yes I am aware but after trouble shooting I am fairly sure my 3060 ti isn’t the issue so I need to figure out if the cpu is fried or if it’s the mother board is there any way to do that?

Try a different video card, a different motherboard, or different cpu, and even a different power supply.

Tried different gpu and ram no difference unfortunately I don’t have a new cpu or motherboard on hand will I just have to sent things back and see what is broken and what is not

Is your PC switching on, right? 

Unplug  power cable  from SMPS .Remove  CMOS battery and wait for 5 minutes and reinsert try to boot.

Replace  cmos battery with a new one. Does your motherboard have built-in speaker. If not inset PC motherboard speaker

I tried removing and changing the battery but I didn’t leave it out for more than a minute tops so I’ll try taking it out for a bit longer
