Briefly dropping signal on Windows startup

post #1 of 8
Thread Starter 
This is something that is really starting to irritate me, and it never used to be a problem:

During Windows 7 startup, between the black spiralling window screen and the blue logging in screen, the video signal will be dropped for a brief period of time, resulting in a black screen and sometimes It even lasts long enough for the monitor to start displaying it's 'no signal' message. This happens on both my Nvidia systems. Why does it happen? It used to be all smooth transitions.

Oh, right. I removed my sig rigs because they're currently changing, but at the moment it's:

EVGA GTX 580 3GB
Intel Core i7 2600k
Gigabyte H67MA-UD2H-B3 (F8)
G.Skill 16GB F3-10666CL9-4GBXL
Asus Xonar Essence STX
Windows 7 x64
Nvidia Forceware: 306.23

The other system that does it is similar, but has a GTX 285 in it.

here is a video to show exactly what the issue is:



Note that the "Starting Windows" screen is cut short because of the SSDs. The point is that instead of displaying the blue log in screen after that, it just drops the signal and then picks it up again after it's on the windows desktop. Does anyone else get this?

Even more annoying is the fact that it does it when I launch Diablo II. It doesn't do it every single time, but most of the time there is no signal when the Blizzard intro is playing.

I've gotten this a couple times or something very similar. Usually happens on boot as well and when I check event viewer it shows display driver stops responding but recovers. See if you get something similar. I'm on nvidia drivers.

What physical interface (VGA D-Sub, DVI, or HDMI) are you using between the monitor and the video card? If you're using HDMI, it could be that the resolution of the startup screen is different than your main desktop, and sometimes it takes HDMI connections a little while to do a new digital "handshake" in order to transition between resolutions.

For example, when I switch between 720p and 1080i channels on my cable box (which is set to output the channel's native resolution to my 1080p HDTV) it takes ~0.5 seconds to show the new channel, during which time the screen goes black. Same thing could be happening with your video card and monitor.

It's probably when your graphics card is changing from bypass to operational. Why is this such a big deal?
APU what?

My system does this too. As long as nothing else is wrong, I wouldn't worry about it man.
