Mysterious problem, no video signal.

Hello!

I have a strange problem so I'm reaching out to you hoping to solve this.

Everything started with a computer that looses the video signal right after the windows loading logo. The same thing happens when I try to boot into safe mode. This computer have been working perfectly fine for about 3 months time before this happened. I decided to re-install Windows 8 pro 64-bit without success.

The following specifications for this computer is: i5-3570, Shuttle DS61 barebone, Intel SSD 520 240GB, and one Kingston 8GB RAM.

In the BIOS i've tried to manually set the video source to "on-board graphics", that didn't work.


After that I replace the processor with a i5-3470S, that doesn't work either so I take out the processor, RAM and HDD and move them to a new DS61 barebone, the problem still presists there. I replace the RAM-module, no difference. Then I take a mechanical Western Digital black hdd and re-install the OS. Still the same problem.


By now I'm getting frustrated and decide to build a new computer with the following components: i5-3570K, Intel DH77EB, Kingston 8GB RAM, Western Digital Blue 500GB, power supply and a chassis of course. I install Windows 8 pro 64-bit, i get into Windows and start installing drivers. After the reboot and windows have loaded I get a black screen and the monitor OSD saying "No video signal detected".

I re-install the machine with a Windows 7 32-bit this time and the problem is still there, I install a graphics-card in the PC and now it's working fine.


Yesterday i re-installed the first DS61 with Windows 8. This time I took it's harddrive and first installed it on my stationary computer. Then I put the SSD in the DS61 and booted up, now Windows started to configure the new hardware and booted up. I decided to update the BIOS for the DS61, and after the reboot the screen was not getting a signal again.


Have anyone here seen anything like this before? All help is greatly appreciated, thanks in advance!

Turns out the problem isnt as mysterious as I thought, I secured the DVI-cable behind the monitor and now I get an image signal.

How come it worked fine in Post and BIOS, and when I installed a GPU in the last computer?
Glad to know your issue is fixed.

Post Screen works even if the signal strength is weak.

It's easy to overlook the easiest solutions it seems.

What about when I installed the graphics card, then I had no trouble displaying an image?
No idea how it worked with graphics card....but at least your issue is resolved  and we know the reason(display cable not connected propelry)

Really didn't expect that to be the issue, especially on 2 different monitors.
