system hangs for seconds?

im running xp pro and every now and again the system will hang for 30secs or so, i can switch between programs, but cannot do anything on the programs?!!

this is becoming a bit of a pain !

any ideas? ive run scandisc and NAV

Thanks

Can you open Task Manager when this happens...or have it open ready...to see what process is using CPU time during this 30 seconds?

As it's a regular occurance that happens for 30 seconds or so you should be able to narrow it down if there is some background process causing excessive CPU usage.



Alec, what exactly does the indexing service do? I think I've turned it off anyway. Am I right in thinking it just speeds up searching the harddisk, by caching locations of files etc. or something like that?

Well thats cleared that up, thanks

It was definately worth turning it off.
