what would cause a monitor to occasionally go black for 1-2 seconds, then resume without any issue

[moskowa]

I have pavilion 6280t with lcd monitor.  I have replaced video card with identical one. same issue.  i can  be on web, or other application, on keyboard or using mouse, and perhaps once per 4 hours of use I get this issue.  I have checked connections. any thoughts?

I have a different computer, but if you are running Windows 7 64 do you get the following message - or a similar message -

NVIDIA Kernel Mode Driver version 259.65 craashed but has sucessfully recovered

I've read that setting up the monitor brightness it disappears.
Never tried since I don't have this problem, just a hint.

This often comes when the graphics card becomes too hot (in games).

[moskowa]

No - I dont get any error message.    this happens once or twice a week.  hp diagnostics finds no errors.  some friends advise me it is the ATI Radeon graphics card that has conflicts with win 7.  I dont know if that is true.

I am running monitor  brightness  only at 80% but will lower it a bit to see if this makes a difference.    I suppose I could test the ' hot graphics card' theory by keeping the case open.  I dont run games or any graphics intensive stuff though.

Did you try and get the latest driver from ATI? 

I have never gotten another one of those error messages ( NVIDIA Kernel Mode Driver version 259.65 craashed but has sucessfully recovered ) since I went to the NVIDIA site and downloaded their (not HP's) latest driver!

It is a long shot, but because you are not getting any error messeges - double check your power settings and make sure (Turn off the display) and (Put the computer to sleep) are set to NEVER.

  Control Panel -> Hardware & Sound -> Power Options.

Stewjackmail -   Yes - I have gotten ATI latest driver and this issue has still occurred.   What is your thinking regarding power setting suggestions?  HOw would those changes you recommend make a difference, and why after 18 months of computer use would this become an issue?    my monitor and hard drives turn off after some period of time- no issue waking up and I can be on the computer straight for 2 hours and then a black screen occurs.  Could it be insufficient power from the power supply?  or failing PCI e  slot?  thanks for you thoughts

[stewjackmail]

Yes, I don't believe anything should happen if you were moving your curser, etc. within whatever time period you have set in your power settings.

Before I fully understood that that  (Turn off the display) and (Put the computer to sleep) were pre-set to active within 4 hours - I got freaked out and thought my monitor had died or maybe the computer had crashed.  When I moved my mouse it took more than a few seconds to recover from sleep.  I never used either setting, and thought they were only for laptops. It was your statement "perhaps once per 4 hours of use I get this issue," that made me wonder. It was just a last ditch suggestion.  I have run out of ideas.

I was always nearly certain my problem was software-based, because I would boot up a live-cd of the Ubuntu/Linux Operating System, and never had any problems at all!  I could watch 720P streaming flash video! Linux live-cd's only load the basic (generic) 2D video drivers, but that gave me a lot of information.

Hi moskowa,

you should rise it (to maybe 100%).

You don`t need this - it was a hint for stewjackmail, who 'highjacked' your thread. :-)
