Comp beeps once, but no display

By bountyclaw ·
I turned away from my computer for a second and caught strange flickering on my monitor. when i looked back, my monitor was basically changing different colors and my desktop image was skewing(kinda like when you try to watch basic TV with bunny ears) I couldnt use my key board or mouse while this was taking place. I ended up having to force restart the machine. Now, when i attempt to boot it up, it turns on the fans come on, keyboard boots up and it beeps once (same beep it always used to do) but thats as far as it goes. no image displays on the monitor and the mouse will never load up as well. Ive left it in this state for a few minutes, thinking it might just be my monitor, waiting to see if i hear windows start up sound through my speakers. Nothing, it seems like it won't boot anything past the initial beep. Any ideas?

We would need the machine type model, is it a desktop or laptop what version of windows are you running if your running windows if not what OS are you running then we can work out what the one beep means and its a post error.

Because it's a NVidia Chip Set here

by OH Smeg Moderator In reply to Its from Ibuypower

I would say that the Video card has gone to Silicon Heaven and needs replacing. You should first however look up the Video Card Makers Web Site not NVidia here and see if they have issued a Recall on this model Video Card.

If this was a complete System that you purchased you'll need to contact its maker for any possible Recall Notices.

NVidia Makes the Chip Sets not the actual Video Cards or M'Boards here so you should be dealing with the makers of the individual Circuit Boards.

But just to double check you should test the Monitor here on another computer to make sure that it hasn't failed.

Onboard has blown?

by Jay Purple In reply to Comp beeps once, but no d ...

Have you tried using a graphics card / different graphics card? the Onboard blew on a old pc of mine once, and would not start afterwards (no VGA detected) so I borrowed a video card from a friend, plugged it in and it all ran smoothly ^o^
