Just got 77.77 yesterday...no luck. Let me give my story on this exact same problem.
It started a couple weeks ago, like everyone else here, out of nowhere. One day all videos played fine, and the next they didn't. It happened while trying to watch "Shaun of the Dead." Media Player version 10 said I didn't have the right codec. The movie was an mpeg and I never had any problems with mpegs so I downloaded GSpt codec information appliance. It said I needed the XVID codec. I downloaded that, and the first time I tried to watch it my machine locked up hard. These were my specs at the time:
AMD Athlon 64 3200+
DFI Lanparty UT nForce 3 250gb motherboard (nforce 3 chipset, driver version 6.39)
NVIDIA GeForce 6200 128MB video card (not sure what driver version it was, it was a previous update before 77.77)
1 GB RAM
Maxtor 80GB hard drive
XP Service Pack 2
Media Player 10
Here's what I tried:
1. unistalled XVID codec. same problem.
2. upgraded to DVIX 6.0. Still froze whether I used media player or DVIX.
3. uninstalled GSpot.
4. reinstalled DVIX 5.0, nothing worked.
Then I came here. On starjax's advice I updated video card drivers to 77.77, then I updated nForce 3 chipset drivers from NVIDIA website.....BIG MISTAKE. Upon restart with the new mobo drivers, first windows would not boot. When it did boot, it wouldn't recognize my system managment bus, PCI bridge device, IDE controller, on-board LAN, or on-board sound....all the things that the mobo drivers were supposed to update. So I reinstalled the drivers I found when I built my system. That's when I realized that I had a higher version number originally. The nForce 3 chipset drivers I HAD were version 6.39 (device manager tells me all the driver components like SM bus, PCI bridge, LAN, and sound from 6.39 were published in january of 2005). But the drivers you can d/l from NVIDIA and DFI are version 5.10, published on September 17, 2004. So it seems I had newer motherboard drivers than either company's website??
I also changed AGP to 4x in BIOS with no effect.
Now, everything works again, EXCEPT ALL VIDEO FORMATS AND STREAMING ONLINE VIDEO. Games seem to work fine, BF2 intro video plays and Guild Wars plays ok. At least all my mobo components work again and I can play audio again using on-board sound, but no dice on video. What's most puzzling to me is why all of us had the same problem out of nowhere one day, when everything worked before and we had no system reconfigurations. And all around the same time too, within the last month. It kind of seems like a RAM problem to me at this point. Sorry for the lengthy post....just trying to be specific.
ALSO: during the motherboard driver update/uninstall/reinstall, BIOS halts with a keyboard error "KEYBOARD IS LOCKED OUT. PRESS F1 TO CONTINUE." BIOS and windows won't boot unless I physically press F1, which I never had to do before. Once I'm in windows, the keyboard works fine, so it's not like windows can't detect my keyboard. Suggestions?
