also, what cpu / ram / disk / free space do you have?
you can also run a chkdsk on the drive

Try older version of NVIDIA Driver
bbkevinAuthor Commented:
Windows 7 seems to have pre-installed driver.
I tried to download the old version (exe) from HP, but after installed, the driver version still show the pre-installed one.
Do I need to removed the current driver manually?
How do I remove the current drivers?
that does not answer my question about the disk - but we'll assume you have enough
were the methods from the link any help?
bbkevinAuthor Commented:
uninstall app from program and feature with driver or go to device manager right click on display and unistall and select remove drivers too.

restart your pac and install fresh driver from nvidia.
so you did not try what i posted at all ? or did i miss something?
Can you explain what you mean?
What are you doing? What are you using? How is the lag represented?
I.e. are you browsing a site and it takes a long time to display?
Are you opening an application and it is taking a long time to open? etc.

Hi Nobus,
I have tried all the things in the link you provided. but the lagging problem still exists.
So I suspect this maybe a driver problem.
I tried to install the driver from this link
but the installation program does not allow me to install...
what error, or message do you get ?
remove from add and remove program restart and download driver from and install
We are off on the driver trail again without actually knowing what is meant by "lagging".

What type of "lagging" are you getting? Lagging mouse pointer? Lagging keyboard input? Lagging when opening a program (launching a browser or Office program)? Lagging when watching a video on Youtube?

First thing I would check is to make sure that no program has gone rogue and is eating up the CPU time...  check in Task Manager> Processes> CPU and see if something is using too much. ( Had a client that had in stalled Thunderbird Email and it has a known bug, after ending it, all was fine)

Do you have more than one AntiVirus program running? If not, are there any traces of old  AV in machine.

Too many questions to be chasing after your drivers. The drivers installed by Windows 7 usually work. I have installed on about 5 different makes and ages of machines and the Win 7 drivers always worked fine.

Other question just came to me.
Is this a new installation of Windows 7? Was it upgraded from Vista?

If so, did you do a clean install or an in-place upgrade through the desktop?

I have found that desktop upgrades cause lots of problems and strongly suggest a clean install by booting from installation disc.

More food for thought.

My computer will at unpredictable times halt everything (freeze) for 1-2 seconds and then resume.
and then again.....
Sometimes, the wireless network will disconnected.
Sometimes, the video / sound cannot play smoothly
Sometimes, the webpage cannot load...
That sounds like some application is running in the background whether legitimate or malware and is impacting your CPU performance..  There is a desktop gadget included in the OS that monitors CPU performance (2 circles attached to each other) that you can use as a rough way of seeing if that is the problem.
More precise is the Task Manager if you leave it open. (be sure to click "Show processes from all users" )
in the processes tab.  

Do you get notices after this one or two second hiccup that a driver was restarted i.e. video?  Check the system messages to see whether it is reflecting an issue and when submitted to MS a solution to correct this issue.
Your system is experiencing hiccups not lagging problems.

update drivers were available.
i would install another fresh OS on a separate partition or other disk -  to test if the problem comes from software or hard

In the Event Viewer, I find the followings, but I do not know whether it is related to hiccup.

Event 10, WMI (7 Days: 22)
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

Event 1000, Application Error (7 Days: 45)

Event 1001, Dhcp-Client
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x002354201EE0.  The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Event 1101, .NET Runtime Optimization Service
.NET Runtime Optimization Service (clr_optimization_v4.0.30319_64) - Failed to compile: System.Web.Extensions.Design, Version=, Culture=Neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=msil . Error code = 0x80070005
The first three might be reflective but not clear.  i.e. the first

The second is the chrome application crash. See if there is an updated version of chrome available.

The third one deals with your computer being unable to renew/refresh the IP because the DHCP server is not responding.  This could show up as a hiccup when the IP lease expires and the DHCP is not responding.
Usually the system begins the process of renewing/refreshing the IP way before the lease expiration.
