Can anyone help on this scrolling problem?

Question

All of a sudden scrolling with the mouse on my computer produces a jerking effect, i.e. it is no longer smooth. Watching streaming video on full screen is also jerky. It wasn't like that just a few days ago. I am at my wits end. Can anyone help? TIA

Answer 1

ram or processor is busy doing something else



RAM and Virtual Memory check – XP type taskmanager

========================

Open up the internet to eg yahoo answers and have a few things open .(eg Word excel or a couple browser pages)

If you normally play music, play that. Close down anything else just for this test.



Open Task manager >performance tab

Look at the RAM usage in the physical memory (k). If you are using more than 60% of your RAM while your computer is only doing the above then there is not much left for video or games. You may need to install more RAM

1 Gig for XP, 2 Gig for Vista



Look at the PF usage. That is the virtual memory . Your virtual memory minimum setting should be more than what is being used at this moment.



Your virtual memory should be set to 1.5 times the amount of RAM you have. Eg 1 gig RAM, therefore 1.5 gig Virtual Memory



Right click my computer icon >properties > advance tab >performance settings > advance tab > virtual memory change > select the drive with the operating system on it (normally C:) bullet custom. Enter the min and max value as one and a half times the RAM you have. In this example, if Ram is 1 gig then choose 500 min and 1500 max. >set



Remember to have your minimum setting more than what was being used in the test.



Your computer is now set for optimum performance for the RAM you have





if your processor is busy

Also while your computer is in good nick you should download and install superantispyware and Spybot –Search and Destroy because when malware gets going you will not be able to access the net.





Clean Up Computer

===============

Download and run superantispyware. I was put onto this program because of an annoying popup (XP or Vista plus all OS preceding)



http://www.superantispyware.com

Superantispyware is a good program and remember to update it before scanning. A scan may take 45mins.



Note Superantispyware has powerful reset tools that will set stuff back to windows defaults.

To use these tools click preferences >repairs. This may be handy to reset IE URLS if you have annoying pop ups.



Also set up tick boxes that you want in the other tabs as you require.



Spybot – Search and Destroy

=====================

http://www.spybot.info/en/download/index.html

in the immunize sections you can do something with activex controls – see link to Javacool.



afterwards clean up the registry with this

Clean up pc and IE

==============

To clean up run this Microsoft’s windows live program. It does registry, spyware , virus , disk clean up and defrag



XP Users http://onecare.live.com/site/en-ca/defau...

http://onecare.live.com/site/en-au/default.htm



Vista Users http://onecare.live.com/site/en-ca/cente...



Run the full safety scanner, it takes a few seconds to install the scanning files but when you start the scan, it takes 2 hours or more. So once it starts to load x file of x you can leave the computer and go to bed etc.



Then at the end of the scan it asks you to set it running full time.



Think twice about setting it to run in the background as it could be another thing to slow you down. However, it may be worth while if you have no other security programs running.



Consider the following options:

I personally run Norton 360 which is full internet security and run superantispyware when I want to.



So if you don’t have a decent internet security program then perhaps run the superantispyware with your antivirus in the background.



If you sick of antivirus programs that don’t work perhaps run onecare full time and run superantispyware whenever.



Now you should be flying and Onecare has even set up a new system restore point for you.



Note onecare does other stuff as well. Click on the menus on the LHS column.



add onecare to your favourites





IE7

=====

Over time IE7 seems to set its own (or programs do) tick boxes in the advance tab.

In IE7 Tools >Internet Options >Advance Tab

Click Restore advance settings defaults

Tick empty temp files when browser closes (this empties the cache, which if not empty, will stop you from going online).

Bullet disable phishing filter

Delete Browser History, cookies the whole lot regularly.

Close the browser to set the settings.

NOTE: 2008 will be the year of add on malware and spyware. I advise NOT to install active x when asked to on unknown websites. If you allow an active x install and it contains adware or such, no antivirus or anti-spyware will find it, because you have given permission to install it. The cleanup programs think that you want it installed. It will be very difficult to remove.



Phishing Filter

=========

When first released, phishing filter slowed IE7. Apparently, Microsoft has fixed this through the windows updates. If you like you could try to run it - bullet the enable.

Answer 2

"All of a sudden" is the key phrase:



If your PC is slowing down, or acting strangely, it's probably infected with malicious software (malware).



Use the Discover Tab above to learn more about Malware and how to remove it. And search for Malware on Wikipedia, too.



Ball, optical or laser Mouse??? If ball, clean it or replace it.



If not, try using a sheet of plain paper as a "Mouse PAD" with your optical mouse. If it stops jerking, the desk's surface texture or colour is causing the problem. Glass desk tops cause the most problems because they don't reflect enough light.

Answer 3

there's a abode windows placing, or a browser placing that enables you to set the mouse wheel scroll fee or via an entire internet site with the mouse wheel. The mice with ingredient to ingredient rockers on the wheel can each and every often times reason this symptom too, regardless of the undeniable fact that it is not going 2 mice in a row with one them being kind new. start up > placing > administration panel > Mouse >wheel exchange the checked radio button asserting "One reveal at a time" to the only that broadcasts " strains at a time" set the strains to one or 2 and your sturdy to pass.

Answer 4

try to do a sys restore to before you had the problem
