Screen going blank at random

[denied!]

Well...finally! (nana2)

It seems that I've a solution for the black / blank screen issue. (thx to EVGA!)

I guess all of you are trying to use your graphiccard with your LCD / TFT via DVI. But there is a frequency / timing problem (or whatsoever).
Changing the frequency was one of the first things i did (with no success). But there are a few more options that can be changed in the nvidia control panel.

Because this may be due to a timing issue. One thing to try is to go in to the NVIDIA control panel under display select “manage custom timings” and you want to click on create, and then select advanced down at the bottom right hand side, and there are options for the “timing standard” select “CVT Reduced Blank” click test and then click ok.

(I don't know if it is the exact way, but I could find the right options / buttons at my NVIDIA control panel, with the 190.38 drivers, that were necessary)
NVIDIA control panel under >display-change resolution >button add resolution.. >button create custom resolution >down on the left: expand timing >choose CVT Reduced... >button test and tadaaaaa :bounce:

I'm not (fully) aware of all those timing-settings, what they mean and do there (exactly), but:
Worked for me.

Hope I could help.

Problem denied!

I have a problem with the 9600GT in one of my machines. Sometime during a game, the length varies (1 to 60 minutes), the screen will go blank. Meanwhile the music still seems to be playing, but no input can be had (global hotkeys don't work).

It's something to do with the 185+ series drivers. 185/186/190 all do the same thing. Meanwhile 182/178/etc work fine. It's 100% reproducible with the 185+ series. Not sure if it's a monitor bug or what, but you have to hard reboot to get out of it.

Edit: 186.18 still produce random blanking for me.

I guess I got the solution for my problem :) It's a game causing that troubles. I have two user accounts on my machine. One for me and one for my wife. She uses to play a little game and its maximum resolution is at 800x600 (fullscreen). Strange thing is, that something is going nuts after closing that game. After a reboot or a change of the user account the desktop resolution goes to 800x600. Sometimes it detects the native 1280x1024 and switches back after a few seconds. Sometimes the 800x600 remains. The only way to ensure that system will keep its nativ resolution is to go to my wifes account and switch to the nativ 1280x1024. The resolution will remain until she plays the game again :) Strange thing. That just happens using the newer nvidia driver series.
