Strange Video Behavior

[[email protected]]

My computer has recently started to have problems playing video. The
audio plays fine straight through, but the video will play normal, then
slow down then speed up to catch the audio, then play fine, then slow
down then speed up...etc..etc. This happens with videos or DVD's that
I play in Windows Media Player or Real Player or any player I could
think of.

When I watch videos on YouTube they are very stuttery as well as when I
play video games that used to run fine.

My laptop is a Mobile P4 running at 2.8GHZ with 512 MB of RAM running
at 2.8 GHZ so I know that power isn't the problem.

All of these things used to run fine and this has been a fairly recent
development. I've lived with it for a while now, but decided the other
day to format my hard drive and reinstall Windows (XP Home). Things
seemed to run just fine for the first day, but then it started up
again.

My device manager is showing two display drivers running. When I
disabled 1 of them my display went to 640X480 with no option of
increasing it. When I enabled that one and disabled the other there
was no noticeable difference. I've tried updating the driver, but the
installation program told me it wouldn't install it. I'm not exactly
great with computers so perhaps the version is slightly wrong or
something.

I just don't know what's happening here. Thanks for any insight you
can provide.

Anything else?

What is the cpu usage when the video is playing slow.

Excellent question. I've checked and there certainly is a correlation.
This seems strange to me because I have just reinstalled windows and
haven't put any (to my knowledge) power hungry applications that might
be running in the background. Video used to work just fine on here.
Is there some sort of hardware failure that could be causing this?
Take a look at the image below and it's pretty clear. It hangs around
50% when it's playing normally then spikes to 100% during the slow/fast
cycle. Thanks for the eye opening question.
