i get that error message whenever i try to open any type of video file on both MPC home cinema an Windows Media Player, it started yesterday and the things i've done since last playing a video and this error are:
-uninstalling NVIDIA graphics driver and redownloading it (310m with CUDA).
-downloading some Win 7 updates.
i run a SONY VAIO S series (VPCS1), i5, Win 7 64-bit.
1. What exactly is the error message you get?
2. Does the Device Manager show that this driver is correctly installed? 280.26 dated 09Aug 2011
The answers may help a more accurate diagnosis for suggesesting possible solutions.
At first, you try a System Restore to a point before yesterday , and see if it works . Let us know what happened .
this is what happens when i press play on a video file.
i suspect that i didn't uninstall my previous graphics driver correctly and its causing a problem, is there a way for me to check if my current graphics driver is installed properly or not?
May be problem with Codecs? Try with VLC Player.
i just tried VLC media player and it worked, so i guess that means my computer's fine, right?
and how are both MPC and Windows Media Player not opening, yet it doesn't affect VLC ?
Reinstall MPC and check whether it comes back to life.
Most probably somehow you got your codecs corrupted . As vlc uses it's own codecs, it is not affected by this corruption. If you have installed any codec packs earlier, uninstall it (use the advanced options of uninstallation of Revo Uninstaller Freeware , so that there will be no leftover ); and then install Shark007's FREE Codec solutions - Windows 7 codecs .
I guess your WMP will work fine after it .
I know most of the time we are only groping in the dark - that includes me ( So I am not finding fault with anybody.:) ).
This "somehow" is what baffles me.
Can installing a new display driver corrupt the codecs? - Most probably not. If it were, it would have been reported widely.
Can installing Windows updates corrupt the codecs? Again the same answer.
If I am not wrong, MPC Home Cinema also installs its own codecs. That is exactly why I suggested reinstalling MPC Home Cinema and check.
So my interpretation here is that VLC could play because it was installed later and not because it had in-built codecs.
If reinstalling MPC brings it back to life, then reinstalling WMP should also resolve the problem. That is my line of thinking - right or wrong. :)
