Xorg using 90% of CPU

I suffered a brief (10 second) power cut leading to a hard power off.
Since that time, when I log in to Gnome, my system is very slow to respond.
System monitor shows constant CPU activity even when I am doing nothing.
top command reports that Xorg is using ~90% of CPU.
I have forced an fsck on all drives and rebooted multiple times to no
Since the fault developed I have upgraded to Ubuntu 10.04 but the problem
Xorg version is 7.5.
Graphics card RV710 [Radeon HD 4350]
Currently using Linux driver (afaict - fglrx is showing up in lsmod), but
problem occurs with either the proprietary or inbuilt driver.
Can anyone please suggest steps to troubleshoot/resolve?
