No Signal On Monitor - MSI Z170A-Pro

[Suuraj]

Hi,

This started before one month when everything was working good on system.
I sold my old graphics card in order to update it. And after removing graphics card i connected monitor on on board display port and ther was "no signal" error message on monitor.:
I check following thngs:
1) putting back graphics card: system was booting normally and display was workig f9
2) removing graphics card and using on board display: no signal
3) with on board diplay connected: chnging ram, clearing CMOS didnt worked.

I arrived at conclusion lf issue is with motherboard as everything was working good with graphics card.

So i sent to the motherboard to Service Center as it was covered under warranty. It came back toady (after a month) and i checked it at my home and
STILL THERE IS NO SIGNAL.
Further, even there is No dispaly with graphics card also.

Had call with service center guy and he said that there was no issue with hardware and they flashed the motherboard and it worked.

My qustion is should i try flashing motherboard.? (As i dont want to go to service center again, it will take long time )

If YES. How should i flash the motherboard with No Signal.

If it is not possible how service center guyz do flash it without dispaly signal.?

fan spinning when boot up? check for bend pin when it return from service? we did thermal paste?

Yes, Fans are spinning, All seems normal. CPU was with me when it cam from service centre. I then reapplied thermal paste on it.

pin is on the motherboard, not cpu.

Which pin are you talking about..? All pins seems ok to me.

Update:
Today went to the service center again and they tested same CPU & RAM on other Motherboard and they are getting same problem. If they remove RAM, board is giving RAM beeps. But if they put RAM there are no error beeps but no display also. They don't have spare ram to TEST MOTHERBOARD.

Any ideas about what could be the cause of prob: Faulty Board/RAM/CPU..?

could be the cpu.

could be the cpu.

Today i will be getting new RAM replacement and i will check if it works.
Just is case if i don't get display still and if i go with your theory of faulty CPU, how would i confirm it..?
Any way to ensure that the CPU is faulty?

Update:
Replaced NEW RAM and still No Signal On Display. Motherboard doesn't show any error lights. I just bought CPU few months back and i really don't think so that is is faulty. Any ideas about what can be the issue. ?

You said "Today went to the service center again and they tested same CPU & RAM on other Motherboard"
So, if it not the motherboard, not the ram, that just left the CPU

yes.

Update: Also replaced new RAM and still there is no display on the motherboard.Only two possibilities left now:

1)Faulty Motherboard (40% chance) : Getting no beeps on board when turning it on. and no signal on dislapy to. Processor fan is spinning. If i remove RAM stick it gives RAM error beep.

2) Faulty Processor : I bought this i5 6500 less than year ago, and there was no incident of power spike/display error or any other sign of faulty processor. Every thing was working properly until i removed my old graphics card and connected monitor to on board vga port and got 'No Signal'.

The another issue here is that, service center guys don't have spare processor to check on my motherboard. And also i don't have it. Any ideas what can i do..?
