No display, no beeps, no sound, but computer (light and fans) work

[Roger Meirelles]

Hello everyone,

I built this desktop last year and everything was working fine. Well, long story short, this morning my dog hit the desktop while it was on, immediately the computer shuts down, and when I go to turn it on again: I have power - computer, light and fans go on - but pretty much everything else is not working: no display, sound, beeps or whatsoever. Also, my keyboard and mouse are not on either because neither of them has their lights on.

So, I connected my monitor, mouse and keyboard on my laptop and they all worked fine, so they are not the problem. I am pretty new to this kind of problem, so I really need your help to see what I should do or to figure out where the problem is.

I have opened the desktop and everything - from what I know - was properly connected and all the CABLES are working fine too.

Anyway, I am looking for an answer on how I should proceed with this, and any direction that you guys can lead me to solve this will be great and very helpful.

Thank you,
Roger

-- If necessary, I can provide extra informations or even pictures of the desktop.

Ok, I got it to work.
Someone told me to start the computer with no memmory cards and see if the mobo would beep - which it did (note that it wasn't beeping before). And for some reason I don't know, I just had to shut down the computer and start it again, but now with all of the the memmory cards (like I would do before the problem) and it worked, everything booted and my computer got back to work.
Unfortunitely, I had to run windows repair, because apperently there was some sort of problem with the files. But nothing compared to a motherboard problem!
Hopefully this will help someone in the future.
Thanks again for you support,
Roger

would it be a conflict if keeping your memory card affect the system not starting ? I am just on course learning on beeping diagnosing...
