Help! Cpu red led motherboard no display monitor!

george1990 · Nov 17, 2018

Specs:

Gtx 1070
I7 6700
Msi z270 gaming m3
16 gb ddr4
Corsair vs 550w

Everything is plugged corectly.

The problem i have is i have no display, because CPU red led is constantly lit on motherboard.

A few days ago it booted, when i took it to a computer service it booted instantly and yestarday after having no display for 15 mins idk how it appeared on monitor and cpu red turned off, now again it lit and no display, i have z270 because i thought that my old motherboard was the problem but the problem didn’t resolve.

Should i buy a new CPU? In my mobo manual red cpu light means:

indicates CPU is not detected or fail

Please help idk what to do anymore!

If you can take it back to a computer service I would suggest going back there amd asking them for a complete analysis of what's going on.

You might also want to reseat your CPU. Which is simply picking it up, and putting it back in. Check the thermal paste while you're at it.

Hi,

Thanks for your reply.

I already gave it to a service for an analysis but they didn't discovered anything.

The thing that is frustrating is that i have this pc for about 2 years now and it worked perfectly until last month then it happened, sometimes i have display sometimes i have no display, and when i don't have the cpu red led is lit permanently. I haven't done anything that could lead to this problem.

I know that if the red led is lit for the CPU on mobo that means: CPU is not detected or fails.

I already ordered a new i7, i7 7700 if even that one will have a red led on motherboard meaning that i'll recieve no display then i don't know what to do..
