Win 7 (64x) -Video signal lost at bootup or shortly after

[teamsundin]

Hi,

When booting up into Windows 7 (64 bit) my monitor stops showing video either right after the initial start up screens or if it survives that it may last a few minutes before. When it does it says signal lost and going into sleep mode and I can't get it to wake up from that.

I've tried hooking up to my tv and still the same problem happens so I'm sure it's not the monitor...it will randomly boot up - sometimes it won't let me get into windows, sometimes not. But even if it does, it doesn't last long.

This started only recently so I wonder if maybe there was an update that caused this.

Any help would be appreciated.
Thanks!

Could be, does it let you boot into safe mode? If it does, you need to find what is causing the crash, most likely culprit is the video driver, or chipset driver if it is an integrated video card.If it looks like a driver issue, download and install the latest from the web.

You can also try going back to an earlier restore point, or doing a repair install from the windows install media, or the repair cd, if you created it.

Before you think about faulty Video Cards etc., is it worth trying System Restore to get back to before any problem?

Have you been using multi monitors displays recently?

Do you get the same problem if you test with another user?

it could be just a setting of the primary monitor, meaning, that once Windows boots, it switches to the designated primary monitor. The monitor attached is either set as secondary or third monitor in the chain...

so booting into safemode, you should check which display is set to primary and adjust it to fit the native resolution... you may need to load a generic monitor driver or even attach the TV to the PC, in order for windows to be able to correctly set all settings...
