I have running these processes:
csrss, lsass, svchost (three times), regsvc, vsmon, winmgmt, wros, msnmsgr, msass43, internat, winpppoverether, avgnt, mixer, zlclient, taskmgr, firefox, avguard, avwupsrv.
I have only the service pack 4. And version 9.0b of directx.
I will make the rest of suggestions now.
Thanks
