iBook all of a sudden laggy

[slipper]

hey guys and gals, i posted last night about how 'Dockextender' messed up my computer in this thread... http://forums.macrumors.com/showthread.php?s=&threadid=54096

i managed to fix it by calling codetex and having them guide be through the steps to fixing it. everything seems to be ok now except its noticably more laggy. i know for a fqact thats its not my eyes misconceiving me cause i tried runnign altivec fractal carbon and xbench and the numbers are significantly slower. i used to score 95-96 points on xbench and 3.2 gigaflops on altivec but now i get at most 74 points on xbench and 2.8-2.9 gigaflops on altivec. anyone knows whats going on?

Try re-installing os x (note: you do not have to delete any file) and then see how it works. I did this once to my computer and it felt faster.

latergator you are the man. ill try that soon.

No problem.;) Let us know how it goes once you're finished.

and one more thing, DO NOT do a clean install because this will erase all your data.

should probably start a new thread for this, but is it possible to delete the 'previous system' folders? they seem quite large, and unnecesary, and i have two!!
