    Since a few days I got an problem with Graphics. Most of the time everything is just fine, than, using an second, third or more apps, everything on display slows down, and moving the mouse or typing, each movement stacks a little (around 1 sec).

    Using an Nvidia 640GT with 2GB Memory, I updated to the latest driver: still the same, no difference!

    Scanned the machine with several AV apps, online an local, all ok NO virus, NO malware, NO trojan, just all is clean!

    Any idea what could trigger that problem?

    Thanks for any information.

    Are you using Flash and is it up to date?

    Thanks.

    No, I don't use Flash! But I installed some time ago Silverlight, may that triggers the problem?

    Anyway, I'll just look for to update Flash, if that's installed with any apps.

    And to note: The first time I was getting that problem were with VLC Player latest version a few days ago. I also received the Error Messages from Nvidia that the driver stopped to work and restarted. That still is happen sometimes even after the update to latest driver.

    In VLC Player, while an movie is running and that stacking starts, just moving the mouse a bit on the movie window and all works fine.

    bambamtusa has a valid point pisthai, when you update Nvidia graphics driver the installer prompts the user to choose either clean install or upgrade existing installation keeping settings.

    I used Express. Anyway, the Graphic Problem was before the update of driver and that driver update were just to see it's driver related or not. But I could run that Update again and coos Custom. Will see that works or not!
    Never had such problem before! Could be that it's related to old software from which I still use a lot, special for graphics work.

    Doesn't sound like a graphics problem, if it was, it would happen with just one app open

    Do a memtest86 and a HDD chkdsk

    Both I used the last few days already and shown: NOTHING! As I wrote in the other post, Process Lasso found the file who triggered the problem and I deleted that.

    By the way, the file dwm.exe were located at: \users\{user}\AppData\Local\Temp

    Desktop Window Manager (dwm.exe) is a part of Windows which should be present in Windows\system32.

    Question is, is it supposed to be at that location too? Perhaps a malware?

    Simply answer: YES!

    I checked before deleting with Virustotal and that shown 36 of 56 as infected!

    I'm just wonder why the Virus scan's over the last few day's didn't found it?! The location at \users\{user}\AppData\Local\Temp is inside the hidden folder AppData and may were not checked even I selected ALL files to be checked?!

    Because as I already said and there are many pages talking about it (even Symantec) A/V software is a dying industry...
    Malware detection is not a good approach anymore, it's not suffice for a tight security model, the model has to be in a layered fashion.

    Video cards are responsible for creating the graphics you can see in the computer screen. If the graphic cards are not installed or updated it can not work very well and has a little functionality. So it is very important to update or install Graphic Driver.
