Hi to all,

I usually don't bother much if my laptop computer is slow or hang for some times. But this month, the hangs take longer than usual. I check my task manager and saw that my CPU usage is at 100%. I tried to reboot and see what's causing the high CPU usage, and saw that even after booting my CPU usage is already at 100%. I waited for it to go low before I click on anything (for if I do while its at 100, my computer will hang again and I would need to restart again). Even while I'm in the middle of doing something, my system will hang and slow down. I tried running virus scans and malware scans but found no suspicious softwares.

Please help me. I have Windows XP, Office2007, Kaspersky AntiVirus, 10GB of of free disk space - inform me what else you would need to know about my system that will help you in analyzing this case. Appreciate all the help that I can get.

Do you know what process is hogging your CPU?
In Task Manager, go to the "Processes" tab, and look for the process(es) that is(are) using most of your CPU.

EDIT: Does this happen in safe mode too?
Follow happyrock's instructions.

go to START..RUN...type in MSCONFIG...then click on OK or press ENTER..
click on START UP TAB...uncheck everything EXCEPT your AV and firewall...if its a laptop you have to be careful about what you uncheck or your touch pad and wireless and things like that will not function for you..
google each start up item to decide if you need it to load with windows...unchecking them does not remove them ..they are still available to use...

the next thing we are going to do is turn off indexing ....its a resource hog and if you aren't searching for things on your computer 10 times a day it will only slow down your system....

click on start...my computer...right click on C: drive....properties...on the general tab..uncheck ...allow indexing on this drive....if you do not have the box on your system...

then START...RUN...type in SERVICES.MSC...then OK...scroll down until you find INDEXING SERVICE...click on it and in the general tab set it to DISABLED...then exit

To clean your temp folder, recycle bin, index.dat etc..please download this free tool...


Don't install any Toolbars, or other programs, should it ask you...Just
uncheck the option of installing the Yahoo toolbar....if you get
the slim version it does not have the toolbar thats the one I recommend...

It will put a shortcut on your Desktop.

Click on CCleaner to start it....
Before first use...
Select Options then Advanced.
UNCHECK "Only delete files in Windows Temp folder older than 48 hours"
The rest of the standard settings are fine...

Then click "Run Cleaner"


next get diskeeper lite here...

after installing it...click on the icon...close the "nag" screen...click on your c drive to select it ...then down towards the bottom ...click on defragment now...first time you use it it may take 15 to 30 minutes to complete...do it about every two weeks and it will complete in about 7 minutes...
reboot and tell me hows its running...

you do not have to defrag in safe mode with diskeeper lite and its 10 times as fast than the defragger that comes with windows
