Many factors can affect how a computer boots and runs. The three most common factors that make a computer boot slowly are the programs that start automatically, physical errors on the local disk and fragmented file systems. These problems are easy to fix and can be corrected with no additional equipment. They can be fixed with utility programs that come with your compute and are built into the operating system.
Click "Start," type "msconfig" into the Search area and hit "Enter." Click the "Startup" tab and you will see a list of checked boxes. These are all programs that start automatically when the computer boots. Uncheck any unnecessary programs.
Click "Start," select "Computer" and right-click on "Local Disk: C." Select "Properties." Click the "Tools" tab and you will see three utilities. Under Error Checking, click the "Check Now" button. Be sure both boxes are checked and click "Start." A further window will open, stating that the disk can't be checked while it's in use. Click "Schedule disk check." Chkdsk will run the next time the computer is turned on.
Click "Start," select "Computer," right-click on "Local Disk: C" and click "Properties." Click the "Tools" tab and select "Defragment now" under the Defragmentation section. Click "Analyze disk" and allow the program to run. When it is done, the disk will be labelled with how fragmented the disk is. If the C drive is fragmented, highlight it and click "Defragment disk."
Both chkdsk and defragmenting can take several hours, so be sure not to run either shortly before your computer is needed. You will be unable to use the computer while they are running.
When unchecking boxes in msconfig, read the names carefully to be sure nothing important, such as antivirus software, gets turned off. If you are unsure as to what a program is, leave it checked.
