Timing issue with video/audio

[Retro6]

I have a COMPAQ EVO here are the specifications:
CPU Intel Pentium 4 @ 1.3GHz
RAM 256MB
HDD 20GB
GPU ATi Radeon 9200 SE 128MB
OS Windows 98 S.E

Its always had this timing issue with video and audio regardless of what format its playing. The timing of the video is skippy and the audio sounds like its skipping. I'm also unable to play a number of games on this machine because of this issue some games work but many don't.

At first I thought it was a problem with the GPU or GPU driver but after installing a different CPU and Driver the problem remains.

Has anybody encountered this problem before or knows what this problem relates too?

Thanks.

Oh well I was hoping somebody might of had an idea. My issue isn't listed in google neither so it must be one of those rare issues that nobody has an answer too. The only thing left is the processor and I doubt its going to be that. Its so frustrating when a problem isn't known. Its like something is not in sync.
