OK, so...  SiS 650, P4 2.5GHz, 512Mb, Nvidia GeForce 5200, Ensoniq 
ES1370, SiS 900 Ethernet, Maxtor 40GB HD, Lite-On SHW-160P6S DVDR, WD 
320GB External HD, and a 56K WinModem.

My first thought is the graphics card, specifically the drivers, as they 
change from Ubuntu version to Ubuntu version, and there exists nvidia 
related bugs.

Have you turned _off_ desktop effects?

Also you can enable/disable the nvidia-restricted driver.

HTH
