lenovo 3000 n100: explorer.exe freezes sys temporarily

[trekuhl]

my dad picked up a lenovo 3000 n100 a few weeks ago for my sister for school...first thing i did was blow out vista home and load XP pro SP2. got the drivers done fine and everything. only strange occurrences i have noticed are the screen has a visibly roll in images and certain color tones similar to the kind of refresh rate issue you might see on a old CRT. the main issue is the system was appearing to freeze when using the touchpad, which was a little weird. i kept playing around and noticed it was freezing when browsing in explorer and also when loading pages in IE. looking at taskmgr it appears that explorer.exe was pegging high (although only hitting maybe 60-70%) and when it pegged the processor even taskmgr would stop responding, the entire system appeared to hang for anywhere from 3-10 seconds. i attempted to processExplorer so i could see what dlls, etc where causing the hang, but it also stops responding so i cant see what the heck is going on.

I have disabled startup items just to double check and be sure, but that doesn't help, I decided to do a fresh install again anyways and the problem is still there, which is pretty frustrating. ive also done the KB and reghacks for the duo core processor to make sure that isnt an issue.

ive been searching around as this appears to be tied to this particular system, so I am hoping someone else has encountered the same and has some insight.

i have virtually nothing running in the background currently except NOD32, touchpad, and hotkey. XP SP2 fully patched. i ahve disabled all startup and it does the same.

if i could see in processexplorer what dll was actually called on by explorer.exe then my life woudl be so much easier...

any thoughts?

I got the same problem than you. In fact this is cause by a bad sound drivers in the lenovo 3000 c200 and n100 series. You can fix the problem by downloading the new driver on the lenovo site:
http://www-307.ibm.com/pc/support/si...cid=MIGR-66525

Note that this file will not install the drivers on your computer, it will only copy the drivers to the specify location, (default: c:\driver\win\...)
Then you need to go in the folder and execute the setup for audio drivers...
Hope it will help :-P
