Help for a Slow PC

Can you wash the car or knit a sweater in the time it takes your PC to open a file? How to make it run faster?

• Try starting in safe mode
  Normally, when you start your computer, Windows loads a huge amount of data into your computer's memory. In safe mode, however, you only have access to basic files and drivers. Therefore, the processor is only running at a fraction of its capacity. If your system is significantly faster in safe mode, one or more applications or drivers may be causing the slowdown in normal mode.
  
  To start in safe mode:
  
  1. Click Start, then click Shut Down.
  2. Click Restart, then click OK.
  As your computer restarts but before Windows launches, press F8.
  3. On a computer that is configured for booting to multiple operating systems, you can press F8 when the boot menu appears.
  4. Select Safe Mode, then press ENTER.

• Have you done anything new?
  Try removing any newly installed hardware, such as a printer, or uninstalling any newly installed applications, such as a computer game, and see if that resolves the problem. Make sure that your computer meets the minimum requirements recommended by the hardware manufacturer or software publisher before installing anything new.
  
  
• Clean up the disk.
  Uninstall unneeded programs (especially those that run at startup and/or put something in the system tray), run Disk Cleanup, and defragment the drive. This is a good first step that will almost always take a few seconds off boot time and application loads for any computer. Are you one of those people who leaves their computer on for days or weeks at a time? If so, temporary files will build up on your hard disk, taking up space in your computer¡¯s memory and clogging up other resources. By rebooting, or restarting, your computer, you can clear out these temporary files and improve your PC¡¯s performance. If you¡¯ve never defragmented your hard disk or cleaned out temporary files, or if it¡¯s been awhile since you¡¯ve last done so, run the full service scan to do it all in one fell swoop!
  
  
• Run a full anti-virus and anti-spyware scan.
  You never know what's lurking on your machine, and these anti-malware tools can help you get rid of other PC-clogging detritus on your PC, even if it's not harmful.
  
  
• Clean up the registry.
  This is controversial, as some experts claim registry cleaners don't really help. I've seen evidence to the contrary, so I recommend doing it if you've got a major slowdown. CCleaner is free and worth running.
  
  
• Delete old network connections.
  Your computer may be trying to connect to shared hard drives that no longer exist. In Windows Explorer right-click on any network shares you don't actively use and click Delete. Under Tools, also click "Disconnect Network Drive" to see if there are any others lurking about.
  
  
• Stop auto-starting programs.
  Click Start > Run and type "msconfig" at the prompt. Click the Startup tab and look at all that junk that loads when you launch your PC. Do you really need "Adobe Reader Speed Launch"? Probably not. Turn off anything else that looks useless, but be careful not to disable Windows system components.
  
  
• Rebuild Windows operating system.
  It may be time to wipe the slate clean and start again, reformatting your hard drive, reinstalling your applications, and restoring your data files from a backup. You'd be surprised how much more responsive a freshly reinstalled Windows system can be, as you've wiped out years of temp files, garbled registry entries, old versions of software programs that have been upgraded repeatedly, and all sorts of other electronic junk. Reinstalling is easy if you have the "recovery disk" that came with your PC, and only a bit more involved if you're using a retail copy of Windows XP. Just be sure you back up everything you want to take with you before you pull the trigger!
  
  
• Upgrade RAM.
  This is the one killer trick that will make almost any computer run faster. With an older PC, you will rarely have enough RAM to run today's memory-hogging operating systems and applications, and adding a high-capacity stick or two of quality RAM will give you a quick speed boost. Adding RAM is fairly simple, even for a novice, and you should be able to do the job in 5 or 10 minutes.
  
  
• Upgrade your hard drive.
  This is a more complicated solution, but if you're reinstalling Windows (per the prior tip) you might consider upgrading to a bigger and possibly faster hard drive, too. Hard disk storage is a performance bottleneck on every machine, and magnetic disks degrade over time. Some performance issues could be caused by a failing hard drive, even, and upgrading to a new model could really put some zip back in your system. As a bonus, you can use the original hard drive for backups or occasional storage, if you put it in an enclosure.
