Audio visual glitches, stutter, freezes in gaming and video Vista Ultimate 64

[RyanP13]

I am experiencing an interrmittent problem in Vista 64.

When i am watching a film (normally via Videolan player) or gaming online I experience occassional second/two second long glitches where the sound and video of the media i am watching freezes for a split second.

This causes a buzzing sound (presumably this is the audio stuttering).

It isn't lag and the play back is not constantly choppy. The files (gaming and video) are played from my hard drives not my DVD drive.

My system setup is as follows:

Akasa Eclipse case w/ 2 x Nexus 120mm fans
E6750 w/ Scythe Ninja cooler and Nexus 120mm fan
Gigabyte P35 DS3 mobo
OCZ Vista gold 4GB (2 x 2GB) PC26400 DDR2 RAM
XFX 8800GT GPU w/ Arctic Cooling Accelero 1 rev 2 (Turbo module attached)
Samsung 203B DVD
Corsair 620w Modular PSU
Terratec Phase 28 Sound card

My OS is on a 250GB Seagate II HDD and i have various other HDD as storage.

Any help would be gratefully accepted as it is driving me nuts. I have spent a lot of money on this new rig and am pretty tempted to go back to XP...

I have the latest drivers for everything also.

Thanks

First port of call - what drivers for the nvidia card?

Secondly what codecs are you using? Did you install any dodgy codec packs?

This: Vista Codec Package Homepage is a very good place to start.

I installed these GPU drivers:

Windows Vista 64-bit

As for codecs. I am not sure i think i may have installed some with VideoLan player.

This would not have been a concious decision on my part but i think they ask you whilst installing.

I will take a look at that page you reccomended.

These are the latest: GeForce Release 174

But they're beta (not that it means much thesedays with nVidia) but you may have to disable driver signing checks to install them (in a command prompt type “bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS”).

Videolan has built-in codecs so ought not to be affected by system codecs. What happens if you play them back in Windows Media Player?

[RyanP13]

I am not sure. I always have just used Videolan but with that codec page it looks as though i may not have to anymore. I did like the way i could play .iso files without having to mount them though.

Will look at it more when i get in. It is not just during video playback but gaming also.
