HOW TO MAKE YOUR COMPUTER FAST, AND WITHOUT ANY VIRUS

HOW TO MAKE YOUR COMPUTER FAST, AND WITHOUT ANY VIRUS

Through my research I discovered that these simple ways can help you give maximum protection to your computer, make these steps a daily habit and you will have no cause  for alarm. Just follow them bit by bit;

Clean up disk errors

Run once a week

Whenever a program crashes or you experience a power outage, your computer may create errors on its hard disk (sometimes referred to as a hard drive). Over time, the errors can result in a slow PC. Fortunately, the Windows operating system includes several PC tools, including a Check Disk program, to identify and clean any errors on your computer and to help keep it running smoothly.

Note: You must be logged on as an administrator to perform these steps. If you aren't logged on as an administrator, you can only change settings that apply to your user account.

Run Check Disk:

Windows 7 and Windows Vista users

Click the Start button , and then click Computer.

Right-click the hard disk drive that you want to check, and then click Properties.

Click the Tools tab, and then, under Error-checking, click Check now.

To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.

To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.

To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.

Click Start.

Depending upon the size of your hard disk, this may take several minutes. For best results, don't use your computer for any other tasks while it's checking for errors.

Note: If you select Automatically fix file system errors for a disk that is in use, you'll be prompted to reschedule the disk check for the next time you restart your computer.

Windows XP users

In the Start menu, click My Computer.

In the My Computer dialog box, right-click the drive you wish to check for errors (for most of us, this is the C: drive, unless you have multiple drives on your computer), and then click Properties.

In the Properties dialog box, click the Tools tab. In the Error-Checking section, click the Check now… button. A Check Disk dialog box appears.

In the Check Disk dialog box, select all the check boxes, and then click Start.

You will see a message box that says you can schedule the disk check to start the next time you restart your computer. Click Yes. The next time you restart your computer, it will automatically run through a disk check before displaying your login screen. After the disk check finishes, Windows will automatically bring you to your login screen.

Note: Check Disk can take more than an hour to check and clean errors on your computer.

Remove temporary files

Run once a week

Your computer can pick up and store temporary files when you're looking at webpages and even when you're working on files in programs, such as Microsoft Word. Over time, these files slow your computer's performance. You can use the Windows Disk Cleanup tool to rid your computer of these unneeded files and to help your PC run faster.

Run Disk Cleanup:

Windows 7 users

In the Start menu, click All Programs, click Accessories, click System Tools, and then click Disk Cleanup. Disk Cleanup will automatically begin to scan your disk for files you can delete.

Note: If the Disk Cleanup: Drive Selection dialog box appears, select the hard disk drive that you want to clean up, and then click OK.

Click the Disk Cleanup tab, and then select the check boxes for the files you want to delete.

When you finish selecting the files you want to delete, click OK, and then, to confirm the operation, click Delete files. Disk Cleanup then removes all unnecessary files from your computer.

The More Options tab is available when you choose to clean files from all users on the computer.

Windows Vista users

In the Start menu, click All Programs, click Accessories, click System Tools, and then click Disk Cleanup.

In the Disk Cleanup Options dialog box, choose whether you want to clean up your own files only or all of the files on the computer.

If the Disk Cleanup: Drive Selection dialog box appears, select the hard disk drive that you want to clean up, and then click OK.

Click the Disk Cleanup tab, and then select the check boxes for the files you want to delete.

When you finish selecting the files you want to delete, click OK, and then, to confirm the operation, click Delete files. Disk Cleanup then removes all unnecessary files from your computer. This may take a while.

The More Options tab is available when you choose to clean files from all users on the computer.

Windows XP users

In the Start menu, click My Computer.

In the My Computer dialog box, right-click the drive you wish to check for errors (for most of us, this is the C: drive, unless you have multiple drives on your computer), and then click Properties.

In the Properties dialog box, click Disk Cleanup.

Disk Cleanup calculates how much space you can free up on your hard drive. After its scan, the Disk Cleanup dialog box reports a list of files that you can remove from your computer. This scan can take a while depending on how many files you have on your computer.

After the scan is complete, in the Disk Cleanup dialog box, click View Files to see what Disk Cleanup will discard (if you accept the suggestions). You can select and deselect check boxes to define what you wish to keep or discard. When you're ready, click OK.

You can also select the More Options tab within the Disk Cleanup screen to look for software programs you don't use much anymore. You then have the choice to remove these unused programs.

Optimize your data

Run once a week

As you add programs and files to your computer, it often breaks files side by side to increase the speed of access and retrieval. However, as files are updated, your computer saves these updates on the largest space available on the hard drive, often found far away from the other adjacent sectors of the file.

The result is a fragmented file. Fragmented files cause slower performance because your computer must now search for all of the file's parts. In other words, your computer knows where all the pieces are, but putting them back together in the correct order—when you need them—can slow your computer down.

Windows includes a Disk Defragmenter program to piece all your files back together again and to make them available to open more quickly.

Note: Windows 7 and Windows Vista are preconfigured to run Disk Defragmenter on a weekly basis. If you would like to run the tool manually or to adjust the schedule, click the section for your specific operating system.

Run Disk Defragmenter:

Windows 7 users

Run Disk Defragmenter manually:

Click the Start button, click All Programs, click Accessories, click System Tools, and then click Disk Defragmenter. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Select the drive you want to defragment, and then click Analyze disk. Disk Defragmenter will evaluate your disk and then make a recommendation as to whether a disk requires defragmentation.

If disk defragmentation is recommended, click Defragment disk to clean up your computer. The Disk Defragmenter reorganizes files by placing them together and sorting them by program and size.

Adjust the schedule:

Click the Start button, click All Programs, click Accessories, click System Tools, and then click Disk Defragmenter. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Click Configure schedule....

In the Disk Defragmenter: Modify Schedule dialog box, choose how often, which day, what time of day you want defragmentation to occur, and on which disks, and then click OK.

Click OK again.
