I had this issue... or at least something very close to it.

It's a home built desktop with a nVidia 7900GS... everything was working perfectly and then about 2 weeks ago we found that the display would be simply be "off". We of course had all the power settings and screen saver all set to leave the monitor on always... the PC was still working... if we pushed the keyboard or mouse or even power button the PC would respond... just no picture. A restart was the only way to fix it.... but then it would only be "fixed" for a few hours or less.

We tried updated drivers (the first set of drivers were installed when we installed Vista fresh)... so we tried the latest set of drivers... worked for about 16 hours then the same problem started again.

We then swapped the output to the monitor from DVI #1 to DVI #2... that fixed the problem for a good week.... with no new issues.

2 days ago I reinstalled Vista (unrelated to the graphics card) and tried DVI #1 again.... it's been working perfectly since the reinstall.

So... I lean towards driver issues.... but getting updated drivers may not help. It sounds like your on a laptop though so putting your monitor cable onto another output probably wouldn't help you.


A reinstall of Vista may be the only way to fix this unless nVidia or ATI/AMD have found this to be a larger problem with Vista64 and their drivers and release a patch or update. I've never seen this issue before... and until your post I thought I was the only one that's had this happen. Of course it could be our hardware slowly going bad... but your problem sounds a lot like mine.


I just wanted to tell you my story and hope it helps in some way... good luck.
