hohe cpu auslastung

enjoy2k

hallo.
mein bruder hatte googlet und hier im forum geschaut, um sein problem auf die spur zu kommen; leider ohne erfolg.

bei ihm schwanken seine frames per seconds (fps) bei dem beliebten ego-shoter counterstrike 1.6 in regelmäßigen abständen zwischen 30-100.
sprich: erst hat er 100 fps, dann nach 10 sec. 20 fps, dann wieder 100 usw..

viren/trojaner hatte ich mit mehrer tools und antivir entfernt.
grafikkarten treiber aktualisiert.

was soll er nun als nächstes machen?

hier ein logfile:
