Only get 1 of my 2 monitors when Win7 boots

I'm not sure this is the best place to post, but will try here.

I've been using dual monitors for a long time w/XP & for a few months Win7 Pro. All of a sudden, when I re-boot (or cold boot) Win7, I get the bios tag lines & the Microsoft screen with the moving bars on both monitors. Then get the desktop on my primary monitor and "no signal" message on the secondary monitor, & it stays black. If I bring up "adjust resolution" and "detect", both monitors get my desktop. "Multiple Displays" is set to "extend these displays".

Has anyone else seen this, or does anyone have any idea on how to get both monitors the way they used to be? If I boot XP (have dual boot), both monitors behave as they should. Btw, I'm running an ATI Radeon HD 2600 Pro vid card.

Thanks,

Norm

have you tried lowering the resolution to test

I just reloaded the video driver & got a new version. After re-boot, I see the same problem.

I also reduced the resolution on both monitors (saw the change) & rebooted. I still see the same problem.

try removing and reseating the video card itself

I am using HD 2600 Pro also dual screens and have never had an issue with Vista or 7

are you using 32 or 64 bit

I'm using 32-bit.

Regarding re-seating the vid card, I don't think it's a hardware problem. If it were, XP would have the same problem.

this is true but i always reseat the card and check power connections to the card in dealing with any video issues

are you using a windows installed driver or one from ATI
