freezing when doing 2 simultaneous actions

Hi all:

I'm having strange freezing wih my XP.

I think this happens everytime (not always) 2 simultaneous windows explorer tasks are taking place.
Somethinhg like, opening a folder when another one is still closing.

I already tried:
System restore
Fresh XP instalation
Several registry cleaning programs

I have no more clues.

What can I do now ??

please help.

EDITING: some details more:

Opened the events viewer to check for errors and saw the following red crosses:

SERVICE CONTROL MANAGER (many times)

CDROM
NFTS
DCOM

SIDE BY SIDE (also many times)

Hello

What kind of a computer do you have?...Specs?..
When you installed a Fresh copy of windows XP?...did you select Quick format or FULL format?...
??

You can get brief ideas on your Event Viewer errors here:

Freezing is generally a hardware problem. Software usually will throw errors as it fails.

Could be heat or your CPU running @ 100%.

Monitor your Task Manager and the CPU usage.
If you right click an empty area of the Taskbar you can open the Task Manager or press Ctrl + Alt + Delete

Sorry guys:

I already solved the problem.

Formated the disk and made a new installation.

tks.

Thanks for the update.

Let us know if we can help further in the future.
