Duo CPU [email protected]
Of late my machine has started to run very slow, it does not open when you click onto a file when you click the second time it comes up Program not Responding, then it open on the internet it is worst.
I have ran C Cleaner & Defrag it is still the same I have also ran my Virus Checher
It is running in the days before we had Broadband
My Virus Checker is Kaspersky
try clearing your system of any extras you dont use programs etc.
download IOBIT TOOLBOX PORTABLE 1.1
its a great freeware tool to clean, clear and optimize your system, its a portable so doesnt install on your system runs just by clicking the icon.
run the cleaners, run the win fix tool, and use the starup checker and stop any programs you dont need running at startup.
a) Clear out all temporary files and folders -- use Crap Cleaner click here
b) Scan for malware spyware and viruses --Free Anti Spyware :-
Superantispyware click here

Free Antivirus software
MicroSoft Security Essentials click here
Avast4 click here
AVG antivirus click here
c) Clean the registry -- Use the tool in Crap Cleaner its very safe and also allows you to back up the registry first.
d) Pagefile (Virtual Memory) -- Right click MY Computer - select properties - Advanced tab - Performance -
advanced tab - Virtual memory click change, you can put the page file on a different drive (if you have one), click
custom size and set Initial size to one and a half times the amount of memory you have fitted i.e. 512MB memory
= set to 768MB, set maximum to double your memory amount i.e. 512MB memory = 1024MB click ok.
If your hard drive is full and there is not enough room for the pagefile this can slow down, freeze or even cause the
PC to crash (restart).
e) Cut down on the programs that load at start up -- Start - Run type msconfig - start up tab- untick everything
except for firewall, antivirus and antispyware
and the services that run in the background. click here
) Force Windows to Unload DLLs from Memory
Windows Explorer caches DLLs (Dynamic-Link Libraries) in memory for a period of time after the application using them has been closed. This can be an inefficient use of memory on low memory systems, and may cause problems or delays for programmers developing with Windows DLL files.
Open your registry and find the key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer].
Create a new sub-key named 'AlwaysUnloadDLL' and set the default value to equal '1' to disable Windows caching the DLL in memory.
Restart Windows for the change to take effect.
a) Hard drives /
i) IDE Channels: (Not required if you have SATA drives)
Check the transfer rate, you need to have the transfer mode set to DMA not PIO.
Right click My Computer - Properties - Hardware - Device Manager - Expand (click the + ) IDE ATA/ATAPI controllers right click Primary Channel - Advanced Settings Tab -
If transfer Mode is PIO then follow the instructions at click here to change.
ii) Check for errors and defrag your hard drives -- My Computer - select drive - properties - tool tab - Error checking / Defragmentation.
ii) If you are using Windows XP, Vista or Windows 7 it's a good idea to convert your system drive to the NTFS file system if you have not already. In addition to providing numerous security and data recovery improvements over FAT32 (the file system of choice for Windows 9x/ME and XP Home) it can also speed up your system slightly.
In fact, the only real reason for sticking with the FAT32 file system for any of your data is if you have more than one operating system on your PC and the other OS's can only see FAT32 partitions (as would be the case with Windows 98, for example, which is incapable of reading NTFS data).
To convert your drives to NTFS:
Right click on 'my computer' and select 'manage'
From the computer management window, expand storage and select 'disk management.'
Using the 'file system' column of the upper pane of this window, you can easily check what file system each of your logical drives is using. Make a note of this information.
Now open a command prompt window by going to 'start\run' and typing 'cmd'
To convert a disk to NTFS, type 'convert (drive letter): /fs:ntfs'
So for example, if you were going to convert your C: drive, you would type 'Convert c: /fs:ntfs' at the prompt.
Obtain the newest drivers for your hardware
This may seem a bit obvious, but keeping your system's drivers up to date can give both your performance and stability a boost. Video card manufacturers release updates especially often, and these can often give "significant boosts" to gaming performance as video card in question is "optimized."
Don't neglect the other components of your system either. Your motherboard manufacturer may have released newer versions of its Input/output drivers for your board, and sound cards and other peripherals can also benefit from newer software.
Add more physical memory, this of course means opening the "box" and fitting a memory module, make sure you buy one that is suitable for your PC. Crucial .com click here will guide you through the process of selecting the correct memory. click here for a guide to fitting memory.
I'm with ' Crossbow7' if you have had your PC a while it may be time to reinstall Vista.
If you go that route,preparation is the key.
Make sure you have your COA number to hand.
Get all your drivers, mobo, graphics etc downloaded and backed up on to an external drive.
Download any service packs from here click here and back them up.
Use this to make installing a lot of the more common bits of software we have on our PC's click here
Copy all your personal stuff to an external drive.
How long have you had your version of Kaspersky? One assumes that it's Database is up to date.
CCleaner should certainly be helping by clearing away some of the Rubbish.
