Poor Performance

I am running SW2006 SP 4.1 and I have issues with SWrandomlygetting slower and slower until it shuts itself down. Thereis nothing that I can do to replicate the problem. Sometimesit is editing an assembly, sometimes it is whilecreating a drawingor creating a part.

Unfortunately, our company has let our Subscription contractend,so I can not get the latest service pack.  Is thereanything Ican try to make SW2006 more stable?
