explorer.exe uses much of CPU

Hello!
explorer.exe uses about 90% of CPU after a restart for several minutes and
in about 10 minutes intervals during 720p video playback in VLC Player for
several minutes.
RAM 6GB, CPU Intel E6750. Vista Ultimate x64.

Hello!
I have set 'no page file' for my d: drive (EIDE Samsung SP2514N on my Asus
P5K motherboard) and the problem disappeared. Why is that? I have not changed
'System managed' for my G: drive.

Dima

Sounds like you might have been caching the data and have now stopped?

Thanks f/fgeorge for your reply!
What is the "caching the data"? Why do you think that I have been caching
the data? Why is it now stopped? I have set 'System managed' for my c: drive
(WD5005000AACS ATA) too, but the problem have not reappeared. How to make
sure that d: drive Samsung SP2514N uses UDMA?
