i have noticed my computer RUNNING XP Pro (3.2ghz P4 CPU) has been slowing down for extended periods.
this has affected most noticeably video which runs really slowly, even on the youtube when the whole video has loaded. the sound is fine, its just the video looks like its being run at 1fps

i looked at task manager and svchost.exe is hoggin my CPU power. this is when im not using any other programs. it uses around 50-80MB RAM and up to 90% of my CPU SPEED.
what is this and what can i do to stop it?

thanx for any helpsvchost.exe is a legit WINDOWS file, and you'll see SEVERAL instances of it running at the same time.
How much RAM do you have?only a gig but im upgrading soongig is fine with XP
Open Command Prompt, copy, and paste this:
tasklist /m /fi "IMAGENAME eq svchost.exe" >C:\svchost.txt
Hit Enter.
