Video Problems after installing Power Nap on Windows7

Jump to solution

I am rebuilding my computer (XPS 400) after a hard drive failure, installed OS, (Windows 7), and other programs without issue. I have a relatively new U2312HM monitor, (about a year old), Installed drivers and Power Nap software from disk, now the monitor randomly disconnects and connects again while working on the computer. This is not a screen saver issue, it happens when I am active on the computer. Then it would go blank and not come back on no matter what I did with the mouse or keyboard. I have had to do a hard shut down. Computer boots up and all is fine, then it starts over again. Monitor is functioning okay, press menu buttons, get message not getting input from computer. I have a NVIDIA G-Force 6800 video card (original to computer)

Of note, I uninstalled power nap without any difference, also I am not running any graphics demanding programs. I suspect my graphics card is going....anyone have any thoughts?

Computer specs XPS 400, CPU speed 3.0 Ghz, 4.0 GB RAM

According my computer specs, what card would be appropriate should I need to replace it?

Hi wla57,

As the issue occurs when clicked on a link, you may try to copy and paste the link in a new browser window to see if that works.

Also, as the issue is related to Office 2003 and IE10, I would suggest you to post the issue on Microsoft Forum as well.

Please feel free to reply for any further assistance. I will be glad to assist you further.

Thanks & Regards

Hi wla57,

Dell has not tested the system with windows 7 and the drivers for same are not available on the Dell support website.

You may try updating the video drivers for your system from the manufacturer’s website.

Also run the Video Stress Test to check for any issues with the video card from the link below.

The link is: http://dell.to/15vqoRn

Click on the link and select ‘Hardware’ to run the ‘Video Card Stress’ test. You may also run a full diagnostics.

Dell has tested the following video cards with the system.

NVidia GeForce 7300, NVidia GeForce 7900 GTX, NVidia GeForce 6800, NVidia GeForce 7800, ATI Radeon X600 XT, ATI Radeon X300 SE.

Please feel free to reply for any further assistance.

I have the most current graphics card drivers, as I have installed a brand new hard drive, and the card I have is the NVidia GeForce 6800. I will check the stress test and get back to you on the results

Hello, I did the stress test, which found no problems. I downloaded the most recent drivers from NVIDIA, then Windows update found additional updates for the driver. I also ran a registry cleaner program. The problem seems to have fixed itself. I will keep an eye on it though.

Well....I guess it's not resolved. The monitor flashed out and back again a couple of times. It seems like it disconnects and reconnects to the computer because I can hear a Windows hardware disconnect and connect sound when it happens. Also whenever it does, any open windows resizes to a smaller size and is located in the top left of the screen, instead of larger in the middle where it was before. I tend to run the windows not maximized. So...any suggestions???

Hi wla57,

As the screen resizes itself after flashing out, the issue seems to be related to the Video card.

Also as you have mentioned that you can hear windows hardware disconnect sound, you may try removing the side cover of your system and check the video card functionality while the issue occurs.

The sound could be the video card fan stopping for a while and then running again, which may be the cause of the issue.

Also try booting the system to safe mode and see if the issue occurs in safe mode. The steps are:

  • Restart or Power on the system.
  • Tap <F8> at dell logo until ‘Advanced Boot Options’ appear.
  • Choose ‘Safe Mode’ and hit ‘Enter’

Keep me posted with the results.

Thanks & Regards

I opened the cover and checked the video card fan when the issue occurred. Fan did not stop. However the fan sometimes sounds like its laboring. When I replaced my hard drive a week ago, I did vacuum out a lot of dust especially on the video card. Note: I used a special vacuum attachment made for vacuuming computers. I am going to try to boot in safe mode and see what happens. Will keep you posted.

The issue did not occur in safe mode. I checked the monitor properties in the device manager and noticed two drivers listed. I am going to uninstall both and reboot. Then install one driver and see what happens. By the way, the disconnect sound is a windows notification sound, the type you get when you plug in or unplug a USB device. Again, will keep you posted on the results.

Just an update, I uninstalled all the monitor drivers, and related software, installed a new driver direct off the Dell website, instead of off the older disk. Did not install Power Nap. It's of no use to me and was probably causing the problem.

The monitor blacked out once, but I think it was before I installed the new driver. So far so good.....I'm crossing my fingers on this.
