After running the suggested anti spyware and anti virus scans, and defrag the hard drive and empty the TEMP files, you can also edit some registry keys to make things speed up. They will only work if you are using Widnows XP. I have done the following registry tweaks many times with no problems at all.



To edit the registry, go to Start, Run and type regedit and follow the instructions below ...



Menu Speed



Go to the Registry key HKEY_CURRENT_USER\Control Panel\Desktop\MenuShowDelay. The default value is 400. Set it to 0 to remove the delay completely, but if you do that it will be nearly impossible to move the mouse fast enough not to activate All Programs if you mouse over it enroute to your final selection. Pick a number that suits your style, make the

change, and then test it until you find a good compromise between speed and usability.



Place Windows Kernel into RAM



It’s a given that anything that runs in RAM will be faster than an item that has to access the hard drive and virtual memory. Rather than have the kernel that is the foundation of XP using the slower Paging Executive functions, use this hack to create and set the DisablePagingExecutive DWORD to a value of 1.



Perform this hack only if the system has 256MB or more of

installed RAM!



Edit the Registry key HKEY_LOCAL_MACHINE\SYSTEM\Curr...

Control\Session Manager\Memory Management\DisablePagingExecut... to 1 to

disable paging and have the kernel run in RAM (set the value to 0 to undo this hack). Exit the Registry and reboot.



Alter Prefetch Parameters



Prefetching (the reading of system boot files into a cache for faster loading) is a commonly overlooked component that can have a significant impact on system boot time. This tweak allows you to select which components will make use of the prefetch parameters. To see which files are gathered using

each setting, clear the prefetch cache located at C:\Windows\Prefetch and then enable one of the settings listed in this hack. Clear the cache and repeat for each setting.

Set the Registry key HKEY_LOCAL_MACHINE\SYSTEM\Curr...

Session Manager\Memory Management\PrefetchParameters\...

to 0 to disable prefetching, 1 to prefetch application launch files, 2 to prefetch boot files, or 3 to prefetch as many files as possible.



Disable 8.3 Name Creation in NTFS



Files that use the 8.3 naming convention can degrade NTFS drive performance. Unless you have a good reason for keeping the 8.3 naming convention intact (such as if you’re using 16-bit programs), a performance gain can be achieved by disabling it. Set the Registry DWORD key HKEY_LOCAL_MACHINE\SYSTEM\Curr...

Control\FileSystem\NtfsDisable... to 1. Exit the Registry and reboot.

Instead of running possibly illegitimate "tune-up" programs, try some of the following steps - You said you virus scanned. Try a malware scan too, if you haven't. Google MalwareBytes if you don't have a program for it. Also, make sure you run full scans with updated databases, not just quick scans. - Google "Free Window Registry Repair". This is a light-weight, useful little utility that can find and eliminate registry errors that could cause these issues. Don't worry if you get results in the 1000s-2000s of errors - this is common for a computer that isn't scanned frequently. - Use Windows' default defrag program or Auslogic's Disk Defrag (which has an optimize feature) to defragment your hard drive. - It may help (maybe) to pop the cover off your computer and blow off the dust with some dust remover (you can buy this at Staples, Wal-mart, etc.). Make sure you spray the can horizontally (do not tilt it), and blow the dust away from your components. Be careful with laptop covers, as they can be a bit tricky to get back on sometimes. I doubt this will make a huge difference, but with older computers a little bit of de-dusting can do a lot. - As for your internet, I'm not sure. First of all, make sure you are getting an accurate reading from your router or modem/router's browser page and not from an online bandwidth meter, as these are only accurate if your line is completely free. If the router displays a sub-standard bandwidth, it could be a wiring problem or maybe your ISP just stopped feeding you as much. ISPs are not required to provide you any bandwidth above the minimum amount guaranteed (for example, if you have a 1 - 2 MBPS plan, you'll have trouble getting them to pick up the slack). If you are supposed to be getting 1.9 at least according to your internet plan, then you may wish to call them. Edit; As a worst-case solution, do a Windows System Restore, setting it to a date before you noticed major slow-downs in your system. This will reset your system to the state it was in on the selected date, though it should preserve your documents, images, etc., not sure about Program Files.

1.Because that most software has automatically function. When you go to the system they would automatically run in the background. So you always use the software is more convenient. But it will also cause unnecessary troubles. There is so much software when you start your PC that the speed will slow down and they can impact of your normal use.

2.because that several different applications will produce some temporary files by using the Windows.The system will save some temporary files in System disk after you visit the web page.If you don’t clean up temporary files folder in time, the disk space will be occupied by these temporary files and the speed will be dropped. What is more important is that a lot of virus and malicious procedures producing in the temporary files cause your systems to stop working.

BEST METHOD you need download the software for cleaning system.

Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. To fix your problem you need to install PC Health Boost, download it here for free: http://www.healthboostpc.com



It's very light and it's the only antivirus/cleaner with a 99.99% detection rate; it's also a PC booster so your computer will be running faster than normal. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.

What To Do When Your Computer Starts Running Slow? -- https://reimagefix.im

Hi



Here is the same advice I give to other people:



You probably have a lot of startup programs in the background when your computer starts. To shut off some of these programs, go to Start, press Run, and then type in msconfig. Go to the Startup tab and disable the programs that you do not want to start. If you are not sure what to disable, you should probably research the startup item first before you decide to disable it. Another problem you could be having is viruses and spyware. If that is that case, I suggest that you download some free anti-spyware and anti-virus programs such as:



AVG Anti-Virus:

http://www.grisoft.com/doc/download-free...



Spyware Terminator:

http://www.spywareterminator.com/...



Super Anti-Spyware:

http://www.superantispyware.com/index.ht...



Ad-Aware 2007 Free:

http://www.lavasoft.com/products/ad_awar...



Avast:

http://www.avast.com/eng/download-avast-...



If you don't have a firewall installed try one of these:

Comodo:

http://www.personalfirewall.comodo.com/d...



Zone Alarm:

http://www.zonealarm.com/store/content/c...



You could also try a free Registry cleaner and registry defragment program:



CCleaner:

http://www.ccleaner.com/



Eusing:

http://www.eusing.com/free_registry_clea...



Auslogics Registry Defrag:

http://www.download.com/auslogics-regist...



Backup the registry before you make any changes to it. CCleaner and Eusing have functions that allow you to do this.

You can also clean your hard drive with CCleaner. It will get rid of cookies, temp files, history, etc.



If you are interested in more programs for your computer, go to http://www.download.com/



If you need more memory, go to www.crucial.com. The memory is not expensive, and there are tools available to help you select the right memory for your computer.



I hope this helps you.

a virus can massively make your pc slow in an instant...

low virtual memory, low disc space, installing inapropriate software can also be the cause of running slow of a pc....

make sure that you install a anti virus and make sure that it is up to date...

check your hard disc for errors...

defragment your hard disc...

uninstall useless software...

upgrade your system... add memory, increase your disc space, upgrade your video card...

if you still have question... your free to email me...

Then click on the "Startup" tab [ XP ]

and you will see everything that gets loaded on boot.

All of those things are candidate to turn off.

turn off ONLY those items that you yourself have added

You may need to start something later if it happens to be a service that is needed for a program or app.

But check it out and you should be able to get your boot speed back up to par.

Run disk cleanup, and de-fragmenter.

These applications are built-in with windows and will help you remove any unwanted files etc.

What's a modem initialization string?

Before your modem software dials a phone number, it initializes (inits) the modem by sending it a series (string) of commands, typically Hayes commands. These commands configure the modem's options for things like error correction, data compression, flow control, and many other parameters. The modem manual should list the Hayes commands the modem recognizes, and what effect each command has.

The important thing about modem init strings is that having the right one often makes the difference between connecting and not. Init strings are fairly specific to each modem. The string that made your friend's modem fly may not work at all for your modem.

Not all programs use simple init strings. Some use settings files, such as Windows 95 .inf files, Mac CCL modem scripts, etc.

Tip: You may also want to try one of these generic init strings:



* AT&F

* AT&F1

* AT&F&C1&D2

* AT&F1&C1&D2



modem strings:

http://www.west.net/~jay/modem/



Tip 2: For K56flex modems, try one of these generic init strings:



* AT&F+MS=56

* AT&F+MS=56S202=32

* AT&F1+MS=56

* AT&F1+MS=56S202=32



Where do I put the modem init string?



start

control panel

phone & modem options

modems

properties

advanced

INITIALIZATION



enter initialization string in box provided

close and reboot
