Slow Computer Problem and its Solution

All most all face this problem many times in their history of windows computing. These symptoms seen once any one or more than one of the below happens with your computer.
1> Hard disk is running out of space.
2> Not enough memory.
3> Hard disk fragmented severely.
4> Too many applications/services loading during start up.
5> Conflict between two or more running programs.
6> Virus.
7> Spyware
8>Others
Solutions :
a) Disk/Folder Properties:
Check the properties of the drive
1> Right click on C:\ drive icon in my computer.
2> Choose properties.
3> Ideally minimum of 25% free space should be there. If it is not there then you may have to delete unnecessary files and folder to release disk space.
4>Keep a minimum of 15% free space in all the drives.(Believe me it will help) Download ccleaner from http://www.ccleaner.com/download . And release memory dumps and and unnecessary file. We have seen it releases in a tune more than 10% of the hard disk space.
b) Not enough memory:
1>Ideally minimum of 256 MB RAM is needed to run a windows XP OS.If yours RAM is less than that you may have to upgrade memory to get good speed.
To check memory size:Right click on the My Computer icon. Select Properties.In the general tab you can see the System memory size. It should be like *** MB of RAM.
c)Disk Defragmenter:
It is a good idea to run defragmenter on a regular basis ideally every month. It will help to keep your drive live longer and healthy.
How to do it:
1>Right click on a drive icon you want to defrag.
2>Select properties.
3>Select the tools tab.
4>Click on the Defragment now... button.
5>Click on the Defragment button. Then wait until it completes defragmentation. During this period your system will be slow.
d) Conflict between two or more programs:
To avoid such unwanted situations you should properly go through the compatibility issues documentation. Usually it is provided by the software vendor itself. For example Zone Alarm has compatibility issue with Cisco VPN client. You can't use both at the same time.
e) Too many applications/services loading during start up
Remove unnecessary programs from start up. Go to Start > Run Write 'msconfig' and enter Select the startup tab. Uncheck unnecessary programs from there except the anti-virus like program which is needed to run automatically.Press OK Restart the system.
f) Virus:
The most deadly program that makes your system slow is Virus. Check your system with a good antivirus software after updating the virus definition.
g) Use a Firewall:
It will help to protect your system from virus and other malicious programs.
h) Spyware:
Spyware considerably reduce the computer speed and internet speed. Use a anti-spyware software to scan your system and remove all the spywares. regularly update spyware database.
i) Scandisk/checkdisk
Run scandisk/checkdisk in Safe Mode by pressing F8 while booting. Have it repair anything it finds.
j) Swap File
When XP runs out of physical RAM, it uses a swap file, also called virtual memory or the paging file. XP swaps information from RAM to this temporary file and then pulls it back as needed. This can slow down your system. Having a large quantity of RAM will minimize the use of a paging file.
k) Increasing Graphics Performance
By default, Windows XP turns on a lot of shadows, fades, slides etc to menu items.They just slow down the computer performance.
To turn these off selectively:
Right click on the My Computer icon Select Properties Click on the Advanced tab Under Performance, click on the Settings button To turn them all off, select Adjust for best performance. My preference is to leave them all off except for Show shadows under mouse pointer and Show window contents while dragging.
l) Bootvis
There is a nice tool provided by Microsoft. It helps in optimizing the booting time. The link to download is as follows http://download1us.softpedia.com/dl/26f ... ootvis.msi
m)Registry
Keep your registry clean. It will help your programs run faster there by increasing your overall computer performance. You don't need to pay for it.There are many free registry cleaners available. You can try RegSeeker. This is a free tool to clean the registry. But before cleaning take a back up of the registry. You can download it here http://www.hoverdesk.net/dl/en/RegSeeker.zip
n) System File Checker
If you have XP installation cd then check if all system files are intact. To do that insert the XP cd into cd/dvd drive. Then type the following command in run elevated prompt. sfc /scannow and press ok. The system will automatically check if any system file is corrupt and it will repair it automatically making your system more stable.
If none of the above helps you in recovering your computer speed, We will suggest you to go for the last option, i.e formatting the OS drive and re-installing XP again. ( many computer experts suggests to reinstall XP at least once in a year. It will help in maximizing the computer speed and some times life too, because it will eliminate all the conflicting programs in your system otherwise which are virtually undetectable)
