Answer 1

No problem!



Check the hard disk for errors...



If you're using Windows, you can use the Error-checking tool to check the integrity of your hard disk, including file system errors and bad sectors.



To run the Error-checking tool:



1. Click Start, click My Computer, and then right-click the local disk that you want to check (usually, this is drive C).



2. Click Properties, and then click Tools.



3. Under Error-checking, click Check Now…. Make sure both check boxes are selected, then click Start.





Don't use a program? Get rid of it...



1. Click Start, and in Category View, click Control Panel.



2. Click Add or Remove Programs, and then click Remove Programs.



3. Scroll through the list and examine each program. Windows XP lists how often you use a program and what day you last started it.

Note: Don't remove anything labeled "Update" or "Hotfix." These things improve the security of your computer.



4. Click each program you no longer need, click Change/Remove, then follow the prompts to uninstall it.



You may have to restart your computer after removing a program. After your computer restarts, repeat steps 1 through 4 to remove more programs. *You must be logged on as an administrator to add or remove programs.*



Get rid of temporary files... When you delete these files, you free up valuable hard disk space for other uses. CCleaner: is a freeware system optimization and privacy tool. It removes unused files from your system - http://www.filehippo.com/download_ccleaner/



Go to start > programs > accessories > System Tools > disk cleanup > all files > more options > system restore and shadow copies > click cleanup... This will remove all but the last restore point. You will recover alot of disk space. As long as you don't have problems with your computer... Do this as often as needed.



Computers tend to save changes to a file to the largest continuous space on the hard disk, which can often be in a different place than where other parts of the file are stored. Over time, your hard disk can become "fragmented," which means your files are scattered in pieces across your hard disk. Every time you go to access a file, then, your computer must search the entire hard disk to find all the pieces related to that file. Excessive fragmentation slows down your computer's response time, so it's a good idea to defragment your hard disk often. Go to start > programs > accessories > System Tools > Disk Defrag > Run it! But I use this free defrager thats better and alot faster... Auslogics Disk Defrag: http://www.auslogics.com/en/software/disk-defrag



Apart from these solutions, there are of course other things you can do to speed up your computer. Look at disabling extra visual effects... To do this... Right Click on Computer on Desktop > Choose Properties > Advance System Setting > Under... Performance... Choose... Setting > Choose... Adjust for Best Performance > Then... Apply > Then...Ok.

Answer 3

Do you have a lot of background programs running like msn messenger, explorer, anti virus, printer/scanner/digital camera programs/drivers etc(icons that you see at the lower right of your screen)? Normally these will eat up your memory causing your Windows PC to slow down.

If you haven't cleaned your registry for some time. You should do it now. The registry in Windows PC contains information regarding your updates, installs, un-installs etc. Each one of those events produces a key. That key needs your PC's resources and free space. So, if you clean your registry, you make more resources available for speed.

Answer 6

i know what you mean because i have experienced it myself. i have also ran my nod32 antivirus but havn't detected any, i also tried using mcafee trial, kaspersky trial, avg free, pc tools limited edition but found nothing.



I even tried all kinds of cleaners and pc boosters hoping to speed up my pc. but no luck.



Then i tried using avira, it detected 4 trojans and 4 adwares that is in my system. since then the performance improved a bit.



Then i used spyware terminator that detected many spywares and adwares.



Zerospyware also found a sogou and other spywares and adwares.



then the computer started to become better and better. but i believe that avira didn't detected everything since it is free so i tried twister antivirus, ran a full scan



after the lond days of darkness i finally found light!!



the AV detected 9 programs that should not be running in my system, it is a combination of viruses, spywares, adware, and trojans.



the computer ran smoothly now..

Answer 8

1- is there any change in your hardware.

next check for TSR programmes... TSR mean Terminated and Stayed in Resident program that can cause your computer to slow down. and sometimes your antivirus program is itself infected. so try uninstalling the existing antivirus program and use another antivirus programm (may be a trial one) after a complete scan uninstall the antivirus and again check..



also, you can analyze task manager to check whether there is a program taking maximum cpu control... try shutting down that program.



another method is ... try to create a new user and use that 'because in somecases user profile can be currupted that can slow down your computer'



try uninstalling extra programmes...



further, computer viruses are programmes designed to replicate and spread.. and there should be a way to make them able to spread... most of the virus nowadays use autorun.inf file on root of each drive to run automatically to set their goals... so keep in mind and check for autorun.inf file on the root of the drive (c,d,e,etc.). then if you found one inf file open that inf file in notepad and try to trace the path and the file just being executed. most of the time these autorun.inf files are hidden from the simple view so to show all hidden files, firstly click on the tools--> folder options ->and then choose view->> check 1- show hidden files and folders and also uncheck 'hide protected system files and folder'.. now you will be able to view autorun.inf file and by deleting autorun.inf file, in 90% cases you will be able to stop virus replication. and other way is to check through the registry with regedit command and check for entries in run paths...

1- [HKEY_CURRENT_USER\Software\Microsoft\Wi...

2-[HKEY_LOCAL_MACHINE\SOFTWARE\Microso...

and normally deleting all entries (not antivirus ones) will save you from virus replication.



next you may scan your computer with an antivirus...

i reccommend you to scan with atleast two different antivirus programmes and also after checking for virus you can uninstall the antivirus program .
