Audio & Video choppy after in/uninstalling software

[rdy4trvl]

Everything was working fine until I installed, then uninstalled various software (web creation & music file) …….and now my computer is noticeable slower. Audio (various .wav files that play when the computer starts {not Msft Windows} and video (played through Hauppauge PVR 350/WinTV2000) are choppy. Prior to this week nothing could even slow down my Hauppauge 350. The problem seems limited to audio and video – don’t notice it any other time. The WinTV2000 seems to be gobbling up CPU power at 75-85% when on….but oddly, one .wav file is choppy at startup –before Hauppauge/WinTV2000 are started. Unfortunately, I don’t know how much CPU Hauppauge was before – it was never an issue.

I’ve defragmented, run virus, diagnostic checks, un/reinstalled Hauppauge software and no improvement. I’m running Microsoft XP SP2, have almost 1gig of memory, 120 gig HD w/40% free, on a Dell Dimension 4550 (2.66Ghz), no network, no gaming…..

Any ideas on what need changing? Otherwise, reinstall XP, programs and copy files.
Thanks

Audio/video issues are typically codec related, but there could be registry issues or missing/corrupt/incorrect file issues also. Now would be a good time to do a little "spring cleaning" and get your pc up to date.

I would start by removing any programs listed in add/remove programs that are no longer needed. Also, any codec packs if you have used them. I would also uninstall all of the audio/video/capture software you have installed. Change your video display driver to a generic/plug & play driver and also uninstall any video driver packages through add/remove programs.

Next begin installing everything again. I would start with the SP2 update and then get all of the current windows updates. After windows is up to date, install DirectX 9c. Then proceed with your MB/chipset drivers, audio drivers (if not part of the MB drivers), and the video drivers, using all of the latest releases (unless there are older video drivers you require for your capture software). That will get your core drivers all up to date.

Then proceed to install/configure/update all of your video capture software.

Obviously, if you knew exactly what was broken/corrupted, you could correct the issue by only installing that one piece. But this way, you get everything replaced and up to date all at the same time.

Before you do anything, perform a registry backup of your system with this tiny app - Rdilly.

All you have to do is click on rdilly.exe and it will create the backup.

I had a similar problem with choppy playback not long ago. Turns out my drive channels had changed from UDMA to PIO. This script will tell Windows to query drive channel status upon next reboot of your system.
