Media center artifacts after waking from sleep

Windows 7 is great and I really want to keep using it, however i run media center on a second monitor and everything works fine until i put the computer to sleep for the night, wake it up then when i fire up media center there are artifacts all over the place.

Logging off and logging back on solves the problem, so I guess memory corruption. Anyone know how to fix this?
Thanks

Hi there valleyman can you update your system specs in your userCP so we know what kind of hardware you are using. This will help us figure out your problem.
The one thing I would say in make sure you have the latest video card drivers.

OK, i have updated it. Essentially

Core2 2.13
[FONT=Verdana, Arial, Helvetica, sans-serif]Gigabyte GA-G33M-S2[/FONT]
2Gb OCZ DDR2 800
7600GT
USB DAC soundcard
19" TFT and WVGA projector

This problem never occured with vista media center. All drivers are up to date

can anyone shed any light on this?

I have the exact same problem, though not from waking up from sleep but from when I switch from Windowed mode to Maximized mode. Or from Initial startup of Media Center...

I've had this problem in Vista as well..but after looking around and finding other people with the same problem I believe I've narrowed it down to the nVidia 7600 that we all seem to be running..I have a 7600GT myself. Someone here; Windows Vista Media Center Graphical Artifacts - Notebook Forums and Laptop Discussion has the same problem and he's running a 7600GS.

So I'm guessing there is something wrong with the 7600 series video cards. But get this: I have dual monitors 1 DVI and 1 Analog (with DVI converter) plugged into my 7600 my Analog monitor never gets this problem while my DVI monitor (main screen) will get this from time to time! So confusing!! I need to upgrade my computer anyway, so I'll just hope it goes away after upgrading.

Yes this sound similar. My main monitor is vga with an adaptor, the projector is DVI->HDMI. Incidentally that link you gave shows the exact same dot pattern I get

I'll be a little clearer. It took a while for me to figure it out as the problem was occuring sporadically, but it seems to work fine until I put my computer to sleep for the night. Then if the next evening I decide to watch something, even if the computer has been on all day, the artifacts are apparent. Coming out of fullscreen solves the problem as you said, but I need fullscreen...

On the other hand I never experienced these problems with vista. I may try swapping the plugs in the graphics card around. Who knows, it may help

Thanks

what was the resolution

I have the same exact problem on my new Media center PC. I installed a clean win 7 ultimate on this , whenever PC comes back from sleep mode if I use MCE then my video is jittery and audio is crap. I have updated video and audio to latest drivers but still no luck.. any one had luck in fixing this issue? If yes please let me know..Thx

USB DAC soundcard

No USBDAC on mine

My PC don't have USBDAC, it is a Shuttle SN78SH, NVidia Geforce 8200 Chipset with AMD 2 socket. I have AMD Athlon II with 2GB RAM running on it. Any other ideas ? Valleyman did you able to fix your problem ? It is same exact problem on mine.

Hi There!

I also have a Shuttle SN78SH. Whenever I wake my PC back from sleep my WMC7 and WMP12 are unusable. Media Player refuses to play any video, while media center is very, very, very slow. For example it takes 1 min for the highlight to change its position.

I rather assume that this is a Windows 7 power management bug, which occurs with specific hardware. I tested with a clean installation of Windows Vista and there waking up from sleep does not have any problems. While a clean installation of Windows 7 I experience serious problems:

1. Windows 7 Ultimate x32 (with x64 tested too, same result) clean install + original mother board drivers (as they came with the Shuttle PC on a CD) -> wmp12 and wmc7 unstable after waking from sleep
2. Windows Vista Ultimate x32 clean install + original mother board drivers (as they came with the Shuttle PC on a CD) -> everything works perfect after waking from sleep

Initially I thought that some hardware device is causing the problem or even BIOS. But my last test rather points out a possible windows 7 bug.

Do you have any new information? Thanks

I also tried to update all my device drivers for Windows 7 from here:
http://global.shuttle.com/download03.jsp?PI=939&OS=8

but still no success.

I updated the drivers from the Shuttle website too but no luck. I'm just shutting down my PC for now. I thought it could be a hardware issue but looks like you have tested on Vista and it works fine . Thanks for the update. I'll post if I find the fix.

Hi, I know its been a long time, but this finally seems to be fixed.

The problem seems to have been related to 7600 cards, but nVidia have finally fixed it with the 196.75 drivers. Now a very happy camper, just disappointed it took nvidia so long to sort it out

Valleyman, I was little excited when I saw your post but unfortunately Nvidia pull the 196.75 driver out. Looks like there is a Fan issue with this version so I have to wait again now. Thanks for your update though. I will be keep checking NVidia for the next release.

Trying running through the "Configure your TV or Monitor" option in Settings->TV.

Worked for me when this started happening after a few updates I did.

Any new information regarding this topic? It's been almost a year and sitll no fix?

Hi All
Just a few comments based on my personal experience:

I've seen artifacts appear when video card memory is either failing or is running too hot. Is there enough ventilation between the memory chips on the video card? Maybe add some video card memory heat sink, or, add a slot cooler. Maybe improve overall case ventilation.

This may explain why some folks "don't" experience this issue when the system has been completely shut down. I wonder if the Video card is still getting power when the system is in sleep mode. Also, it also may explain why there aren't any artifacts when switch to non-full screen mode.

What about "slowing down" the memory bus/clock on the video card? This test will immediately rule in or rule out the video card memory.

cheers!

I personally believe its a hardware issue with the 7600GT. I have not heard of this problem being unfixable with any other video card. I have since moved to using laptops only so I don't even use my desktop anymore and no longer experience this issue on my laptops.

Just my .02.
