EZDebug CPU Light Please Help! Z270 MOBO

[AdonisThaDon]

Good Day.

I was given an AIO which works 100% on the previous build to replace another AIO which is also working 100%. I had cleaned up the old thermal paste from the cpu and removed the cpu to remove harder to reach thermal paste.
Placed the cpu back in, thermal paste, AIO, plugged in all necessary connections in correct places, attempt to turn on and CPU light is on with no Display. Doesn’t Boot to Bios neither
I’ve tried reseating all components with the same issue

Pc Specs:
I5 7600k
24gb 3200mhz
3060ti
M.2 512gb
Hdd 2Tb

You might have a bent pin on the mobo bud. Carefully remove the AIO and CPU and shine your phone flash light on the socket. You will see quickly if there is a bent pin.

Yeah I thought that too, upon inspection, seems like all is good.

Are you sure you remembered to reconnect the CPU power connector from the PSU to the motherboard?

Have you tried clearing CMOS (using either the jumper or removing CMOS battery for ~30min)?

Are you sure the cooler isn't screwed on too tightly?

Have you tried with only one RAM module installed?

 

[limadelta26]

Clear the CMOS on the board (like in take the battery out and unplug the PSU from mains and turn it on to clear all power)
I would still take the CPU back out and then reseat it carefully, same with the RAM.

For now, take the GPU out as well as that CPU does have built in HD630 iGPU. Test the system again with just the onboard and see what it does

Power on but no post can be RAM. Maybe some heat paste in the RAM socket?
Did you leave it for about a minute after pressing power button? If the bios was reset it will do RAM training before posting.
Also, reset the bios.

Legit as I am typing the same thing about the CMOS 🤣

RAM training shouldn't be an issue but @odtech makes a good point here as well.

If it doesn't have a jumper you can speed things up by removing the battery and shorting the + and - with a pair of tweezers or whatever works. The board completely powered off ofcourse.

Yes. Reseated all components but the case fans.
I’ll clear the CMOS.
I try to be as gentle as possible with tightening or plugging in things.

I’ve removed all but one ram stick and tried different slots. I’ve tired different sticks too

I’ll give this try

No thermal paste in ram slots from what I can see

Same result with GPU removed.

On the CPU itself are there any scratches or such on the underside where the contacts are? Keep in mind there are a tonne of tiny a$$ SMD components in the centre.

Try take a pic of the LGA socket on the board and the contacts on the CPU and post it

 

[odtech]

Watching you tubers fix customers laptops it happens often that tiny components get knocked off the board doing routine things like replacing heat paste. It has happened to me too but luckily I saw it and could reinstall it. Not exactly the same scenario but I knocked a tiny resistor off next to another component I was replacing while the solder was melted and the result was the laptop still wouldn't turn on. I replaced the lost resistor and the laptop started working.

 

[AdonisThaDon]

I’ve tried all of these methods with no success guys. No burn marks on the cpu, No bent pins, reseated all components including the case fans, tried one item at a time. No thermal paste anywhere but the cpu and the cooler at this moment.

Rather take the photo from the top down bud

Please also send a pic of the mobo socket

 

[dirko.van.schalkwyk]

Also, some phones have a "macro" function when taking a photo for closeups. We need as much of what you are taking a photo of in the frame?

Apologies.

 

[AdonisThaDon]

I’ll have to get back to this later as Im needing to head to work. I’ve taken the pc to a mate who deals with computer repairs hopefully he can help.

Please also send a pic of the mobo socket

I’ll ask him to take and send some photos

Will do. Will make sure to do this

I've found this useful at time.

Howzit bruv. Sorry for the delay, just at work. This the only photo my mate has sent. He seems to be struggling as well

You was right brother.
