Error 55: No monitor signal, reboot cycle, help!!

[nick1627f]

Hello all
I have an unfortunate problem: let me explain.

One day my Graphics Card was unresponsive. It is an EVGA GTX1070FTW (see parts below).
After testing and EVGA 24/7 customer support, I deemed it faulty due to my previous troubles with the card. I sent it in for an RMA. I was never able to connect to integrated graphics, and it still doesn't work.

After 1-3 days turned into 2 weeks, he cats finally arrived. To my surprise they sent in a EVGA GTX1080SC. I was happy; ready to benchmark it!!

But my happiness didn't last for long.

After putting the card in; it was responsive. Lighting up and all. However: STILL NO SIGNAL ON THE MONITOR.

But something changed.

With graphics card unplugged: motherboard does not send any codes or light up.

With graphics card on: mobo turns on and ends on error code 55 before entering a reboot cycle. Nothing changes.

So I mess around with the RAM sticks because error 55 = memory intialazation error. Switching places, taking out etc. I would do this again so please help me out with this part.

Still no changes.
Is it RAM? Could it just be dead? Best case for me I think.
Is it CPU? Please don't be CPU!!! I got some thermal paste after getting it on the way back front nyc last night. Could it be a pressure problem?
Is it just the MOBO?

Please help me; I am puzzled. I am ready to do nearly anything. I would really appreciate it.

Thanks,
Nick F



Build:

i76700k
GTX1080SC from evga
gigabyte Z170x gaming 5 mobo
NZXT Kraken x61 240mm cooler
Corsair RM750 PSU



I think that's all that's relevant
Thanks again

Hi, If starting the board with only CPU and CPU fan installed, both 24 and 8 pin power cables connected, still no code?

Thanks, As of right now, with everthing plugged in, I get the code 55

I don't know if I will get the code 55 with only CPU and CPU fan. I can try that; but will not be able to send you results immediately

No problem. Whenever able to test.

Hello hope you are still here
With GPU and RAM out, the motherboard doesn't give any code. Thanks.

UPDATE: computer with only CPU and CPU fan is in a cycle of error 55.*

*Ram and GPU are disconnected

Should I take out CPU to check?
Put RAM in?

55 is ok. Now insert single RAM and see what code getting. Test each RAM slot.
