Kde 4.3.1 started booting slow, real slow, real slow… and logging out real slow. I tried un-instsalling everything since my last update. I then tried moving to the kde 4.3.5. Same problem. Any clues or should I just do reinstall? I am running a ACCER laptop Intel(R) Celeron(R) CPU 550 @ 2.00GHz. I have been using Linux for 10yrs. but no guru… Thanks for any suggestions… 
Did you try run ‘top’ in a terminal to what was running all your resources
I am unable to run ‘top’ during load of kde . the system is running to slow. Running GkellM and CPU is stuck at 99% during load of kde. I have tried turning GkrellM off same thing. Kde also is not remembering last folder view settings… once kde isrunning system runs fine.

Once logged in as user, do this
mv .kde4 .kde4-backup
then to try starting the desktop
startx
All your setting will be in .kde4-backup, as this starts a new kde4 instance
this is my main computer and I don’t wan;t to be wiping out my laptop. I know this won’t realy affect my personal stuff, but I will try this over the weekend. I have 3 linux machines, all run suse. All run flawlessly. I think this a kernel update problem. That’s when think I can pinpoint the problem happening (but I am no expert).
Roll back the kernel from a level3 boot and use yast
Boot to Level 3, then Yast and More… - openSUSE Forums
