My computer is slow

DEAR
  • Issue:
  • My computer is running slow what steps can I do to fix it?
  • Cause:
  • This issue can be caused by any of the below possibilities.
  • Hard disk drive is short on available disk space.
  • Several software programs have been installed/uninstalled leaving behind bad files and/or confusing the software.
  • Data Corruption.
  • Missing Windows updates / Outdated drivers.
  • Computer is overheating.
  • Corrupt OS.
  • Bad Hardware.
  • Solution:
  • Below are steps for Microsoft Windows users that should help speed up the computer or determine why the computer is running slow.
  • Note: If it is just your Internet that is slow see document CH000986 for reasons why this may be happening.
  • Not enough hard disk drive space
  • Verify that there is at least 200-500MB of free hard disk drive space. This available space allows the computer to have room for the swap file to increase in size as well as room for temporary files.
  • Steps on how to determine how much disk space your computer has can be found on document CH000369.
  • See document CH000528 for additional information about regaining lost hard disk drive space.
  • Hard drive corrupted or fragmented
  • Run Scandisk or something equivalent to help ensure that there is nothing physically wrong with the computer hard disk drive.
  • Run Defrag to help ensure that data is arranged in the best possible order.
  • Background programs
  • Remove or disable any TSRs or programs that automatically start each time the computer boots. See document CHTSR for additional information. If you're wanting to see what programs are running in the background, how much memory they're using, and their CPU usage open Task Manager. Also, if you are running Windows 7, you can run Resmon to find out which programs are taking up a lot of space.
  • If you've got an anti-virus scanner on the computer, spyware protection program, or other security utility make sure it's not running in the background as you're trying to work. Often when these programs begin to scan the computer it can decrease the overall performance of your computer.
  • Hardware conflicts
  • Verify that the Device Manager has no conflicts. If any exist resolve these issues as they could be the cause of your problem. Information about how to get into Device Manager can be found on document CH000833.
  • Update Windows
  • Make sure you have all the latest Windows updates installed in the computer. Additional information about making sure Windows is up-to-date can be found on document CH000545.
  • Update your drivers
  • Make sure you've got the latest drivers for your computer. Especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues. See document CH000546 for additional information.
  • Computer or processor is overheating
  • Make sure your computer and processor is not overheating, excessive heat can cause a significant decrease in computer performance some processors will even lower the speed of the processor automatically to help compensate for the heat related issues. Additional information about your processor temperature and was of determining how hot it is can be found on document CH000687.
  • Specific operating system basic troubleshooting
  • Basic Microsoft Windows XP troubleshooting.
    Basic Microsoft Windows 2000 troubleshooting.
    Basic Microsoft Windows NT 4.0 troubleshooting.
    Basic Microsoft Windows ME troubleshooting.
    Basic Microsoft Windows 98 troubleshooting.
    Basic Microsoft Windows 95 troubleshooting.
    Basic Microsoft Windows 3.x troubleshooting.
  • Or go through the other basic troubleshooting steps.
  • Memory upgrade
  • If you've had your computer for more than one year it's likely you're computer is not meeting the memory requirements for today. We suggest at a minimum the computer have 1GB of memory. Additional information about determining how much RAM is installed in your computer can be found on document CH000149.
  • Erase computer and start over
  • Finally, if none of the above solutions resolve your issues, it is recommended that you either reinstall Windows and/or erase everything and then start over. Additional information about how to do this can be found on document CH000186.
  • Hardware issues
  • If your computer continues to be slow after going over each of the above recommendations it's possible that your computer is experiencing a more serious hardware related issue such as a failing component in the computer. This could be a failing or bad CPU, RAM, Motherboard, or other component.

Cd drive has stopped working

Will need some more information. It could be anything from a loose connection on the inside of the computer to a failed drive. When you open the My Computer icon, is the icon for the drive displayed? If not, does the CD drive appear in the device manager? (Right click on the My Computer icon and choose Manage on the menu to pops up, select Device Manager and look for CD/DVD drives). If the drive does not appear in these areas, then I'd start by checking all of the connections to the drive (power cable and ribbon cable) and motherboard. If that does not fix it, check the BIOS to be sure that the on board IDE is enabled. After doing all of that, if you still get no response from the drive, then it is probably time to replace the drive itself.

No video

It's not necessarily the video that's the problem. Anything that would keep the computer from beginning the POST process (beginning of the process of booting your computer) could also result in no video. When you start the computer up, does it beep at all? If so, how many beeps, and are they long or short. The order and lengths of the beeps are the most basic type of error codes. Also, do you hear the hard drive spinning up? And does the CD/DVD ROM drive start up normally? It could be a power supply, your processor, memory, the motherboard or just the video card. It could also be just about anything in the computer if it developed a short, as a single short can cause the power supply to shut itself down so as to protect the computer from being further damaged. I would suggest disconnecting power to the drives, and trying again. If it boots to video, you know one of the drives is the culprit. If they aren't the problem, try removing the memory. It won't boot that way, but if the memory is the problem it will at least reach your POST and give you the option of entering BIOS. If you get that far, the memory is at fault. Then, try the same with any expansion cards onboard. If none of that causes it, then you either have a bad processor, bad onboard video, something else wrong with the motherboard, or bad power supply. Unfortunately, none of that can really be tested without having parts to swap out.
