  1. Hi i just purchased and installed a new g-force 6600GT, after installing all necesary drivers, whenever i play a video file, win media player just freezes and the cpu usage peaks to 100%,

    does this relate to the power supply?

    Hello! Welcome to TechSpot

    What are the specs of the system you install the video card to?

    Sounds to me like a driver issue. What drivers are you using? Are they the ones from the CD?

    At the top of each page at TS there is a driver link.
    You may want to try one of the other ver. of driver
    like 77.89.
    try GURU3D too.
    It does look like a driver prob.

    Ok i installed the latest driver from nvidia.com and used driver cleaner to delete excess files, everything was running superb. Farcry, half life 2 call of duty all handled max graphics settings :D .

    Two days later i switch on pc and the same bull**** with media player happens, no videos play on any player and it causes cpu usage to jolt to 100%, and games work sometimes, and other times they dont .

    Any other suggestions?

    Maybe a bad agp slot.
    Do you have another video card or one
    from before the 6600?
    I'm scratchin my head here too.

    yeah man, the last graphics card worked fine, ive never had this problem.

    The thing i dont get is that when i thought i had it solved, the next day it screws up, games work perfectly at max settings, but no video file or even streaming video from web sites work, it sends the cpu usage to 100%, i have to go to the task manager to and physically stop it to get it back to normal

    I'm having the exact same issue with video files and windows media player. Every time I try to play a video file or visit a webpage with embedded media my cpu usage peaks to 99% and I have to close the process manually. I also use a 6600GT video card but I'm not sure if that has anything to do with the issue. I don't seem to have any issues when running games.

    6600GT Video playback issues

    Has anyone come up with any solutions to this it's happened to me too, had a PNY 5200 FX ultra the fan went and was 2 yrs old so got a 6600GT today, and having all the same problems as you guys and can't find any solutions on the web !! I've tried all the latest drivers, people mention rolling back to 71.89 does the trick but that's not so good for me as I constantly use Battlefield 2, Hl 2 etc...

    Any help on what to do???

    Much appreciated :)
    Feel free to email me too

    I don't know if this is a fix or not.
    nVidia has new set of drivers out 77.77 whql
    They seem to be ok on my 6800 so far,
    I just installed them an hour ago.....

    Still have same problem,

    I got the to be exact, I did try the old 71.89 or something and it works fine for videos !! People mention updating AGP might help well I've hunted for these and can't find for my motherboard, an Aopen ak77-a8N.

    I can't find any fixes either, any help is much appreciated :)

    It's the 4 in 1 driver that has the agp set in it
    Link HERE

    Even with the new driver from nVidia 77.77,
    had the same video overlay prob., I had to go into
    color correction and reset to default to get video's playing right..
    I hope this helps!

    What can I say but a big thank you to SOcRatEs !!! this helped my problem i'm ever so grateful this forum is the best for sorting out your problems !! (IT wise...)

    I was looking in wrong place for agp updates clearly, didn't know about 4 in 1 drivers !!

    All is well I can finally relax and watch a film then switch to some shootin on the battlefield on the same drivers :)

    Thanks again !!

    So when my movies started working, I tried to load up WoW and had MAJOR tearing/graphic errors.. Wasn't just with WoW either. same thing happened in Guild Wars, EQ2, and WC3.

    In the end I got it fixed, turned out it was my power supply unit (PSU).

    On the side of your power supply, there is a sticker it will have six plus readings under DC Output. You only need to pay attention to 3 of them. What you are looking for are the ammrage output of the rails. You only need to pay attention to the positive DC Outputs and these are;

    +5v, +12v, and +3.3v. These are called rails and you need to pay particular attention to the +12v rating as from what I've learned this is mainly what your sound card, and video card use.

    You might have two 12v rails and your sticker would read as +5v,+12v(1), +12v(2), and 3.3v

    At any rate, my PSU was rated at 16A(Amps), however, my video card required 20A on the +12v rail.

    I got a new PSU, one with dual +12v rails rated at 21 amps each and bam! I could watch videos AND my games ran great!

    As a side note, if you get a new PSU, the +12v rails don't add up exactly. From what I was told, you only get 80% of the combined total so in my case, I now have two +12v rails at 21Amps each, so instead of 42, I actually only have 33.6Amps to power my Video card, Sound Card, and CD roms.

    Hope that helps. Cuz I know I was sure frustrated having to watch porn on another computer and game on my main computer...
