EXPLORER.EXE make CPU spike very high when using/clicking out of Start button / Program Tree
Posted on 2003-03-12
This one is unusual.
When I click my Start button, and navigate anywhere in the menu, my performance is sluggish and difficult to use. Perhaps I should back up first.
I'm using a Dell Latitude C640 notebook, with the following pertinent specs:
P4 2.0 Mhz
1 GB RAM
Running: Windows XP, SP1 /w all latest updates
In other words, this thing *should* be a friggin rocket. It performs extremely well doing heavy operations in general, but for some reason, is *dying* when I click the Start button.
To help the troubleshooting, I can tell you that I have tried reinstalling Win XP twice in an effort to get around this annoyance, with no help.
To give some more detail, when I click Start, it pops up instantly...but as soon as I move my mouse anywhere off of the bar or into a new sub-menu, my computer chokes. That is, if I click Start, and then "click out" to make it disappear, there is a good 1-2 second delay before it actually disappears, during which time my computer chugs. Similarly, if I click State, and go to Programs (or any other sub-menu that spawns a new element), it start to chug hard.
It is very hard to explain, considering I was using a laptop with half the speed a month ago, and it never exhibited this problem (was a C600).
From a processor/Memory consumption perspective, the following things are noticable:
EXPLORER.EXE jumps up to as high as 95% when I "click out" from anything on the Start/Program bar and cause it to disappear. No other processes seem to increase in CPU consumption or memory utilization.
I understand that Laptops aren't as powerful as desktops, etc., but this is so bad that it actually makes it difficult to use the start bar and pick programs, because the CPU is chugging away making the mouse icon trip out.
Aside from that, I have nothing to go on! Aside from the fact that I have tried reinstalling, only to find that the problem remains. If this is a hardware issue, I am looking for any help in diagnosing what might be going on...all feedback / suggestions are appreciated.
