[newbie] 7.2 install

[Geoff Thomas]

I upgrade from 7.1 ( which was working well and fast) to 7.2 using 2 iso
images I downloaded. The install seemed to go well. When I rebooted,  my
machine acted like it was running in slow motion. Opening a terminal
window took almost 2 minutes. Opening my browser took forever. The
machine did seem to be working but way to slow to be usefull
Any ideas?
