No signal on the monitor

  1. I apologise if this is in the wrong section...And I apologise for another one of these threads.

    But I'm at a loss what to do. Heres some background info...

    Ok I bought a computer off ebay which came with a P5VD2-MX-SE MoBo. It hard an external PCI-E GFX Card (Can't remember model) NVIDIA I do believe. Since I've had this computer it repeatedly crashed at random times/Applications crashed (with the windows reporting error) and randomley froze.

    I managed to narrow this problem down to the graphics port on the actual mobo been the problem due to onboard graphics working perfectly when I used that, the graphics card itself worked perfectly in another computer and I purchased a new graphics card EAH3650 I think, and the thing still crashed etc. Occassionally it would say the VPU had to reset or something because it failed to respond to commands (when I was using the PC)

    A month or so ago I had problems I think it was that the monitor would display anything OR it wouldn't get past the Windows Loading screen and finally I removed the secondary RAM stick and the computer started working fine again.

    So the other day I had been using the PC and switched it off for updates, was working fine...Then when I switched the thing back on...I got nothing...No signal to the monitor. After this I figured its about time to replace the MoBo so I purchased a new P5N73-AM and installed everything (correctly I assume) hooked everything up GFX card etc...Even bought a new PSU, and I still get the no signal thing...I don't even get BIOS.

    I know it isn't the cable connecting to the monitor I hooked this laptop to the monitor using it...So I'm thinking it's either the AVG-DVI connector or the graphics card...Any input/questions is helpful.

    Thank you in advance.

    Always suspect the cable first... and often it is just the connection socket and plug... remove and reinsert to see what happens, as a good first step.

    Well I know it isn't the cable as I did test it but your right I should have suspected it first lol.

    Right now I just unplugged the HDD, CD drives and still no luck. I find it weird that both the on board and graphics card won't produce an output. Granted I still haven't taken out the graphics card yet.

    The front LED is red for about 15 seconds when booting up...Is that bad? If i remember rightly I don't think it is, but I'm not sure.

    If the monitor doesn't get a signal, it's still possible you do get BIOS, you just don't see it. You could try attaching another monitor, or a different graphics card..
