No video signal

[Ducos]

Hello!

 

I'm having problems with my desktop that I built a decade ago and it has the following components:

 

Mobo: Z68A-GD80(B3)

GPU: Intel i7 2600K

GPU:GTX 570 Twin Frozr and a GTX 680 Zotac AMP

PSU: Seasonic P-860XP Platinum PSU Modular Semi-Passive

 

Last time I used it was in 2016 and just yesterday when I tried to turn it on it didn't give any video signal nor did it power mouse and keyboard.

I pulled it out of the case and tried to re arrange the cables but no result.

Any idea on how I should go to troubleshoot the problem?

I wanted to install the Buzzer but tried and doesn't make a sound but I think it's because I don't know how to connect it.

 

Thank you all for your time and wisdom!

Clear the CMOS, reseat the RAM and CPU and see how it goes. Since it's been sitting untouched for the better part of 3 years, it's possible contacts may have corroded. So you have my to clean the RAM contacts and the slots with some Deoxit.

Reseated the Ram in the slots as stated in the manual.

Reseated the CPU and reapplied the thermal paste.

Cleared the CMOD while it was powered off and also took the battery out for about 2 minutes.

Turned it on but still no video signal and no power to keyboard nor mouse.

 

Can I assume the MOBO is dead?

Do you have a PC speaker plugged in? I'm referring to those speakers inside the case that has a 4-pin connector that plugs into the same area as your power and reset buttons. If so, do you hear any beeps? 

 

Also try unplugging your GPU and use only the onboard video. The issue could also be your PSU. Since you're computer has been left (I presume) unplugged for so long, I wouldn't rule anything out.

Apart from no signal to display and no mouse/keyboard does anything else showing any signs of life? Fans spinning etc

Fans do Spin, PSU fan also spinning and LED that indicate the power phase of the CPU light up

I plugged the Buzzer(speaker) inside the computer but it does not emit any sound whatsoever.

It has the bare minimum to start up.

I just wanted to get into the BIOS|UEFI with PSU,MOBO,CPU and RAM.
