Clean up your computer’s startup sequence

As you install additional software programs to your computer, you’ll notice that they also begin to appear in your computer’s start-up list and load during your computer’s start-up procedure. If you have far too many software programs running in the background, your computer will begin to slow down immensely because each of those programs are eating away at your computer’s resources. Computer resources are only finite and the more it has to be shared the less there is for each software program to use. Removing unused software programs will also remove them from your computer’s start-up list thus allowing more available resources the moment your computer boots up.

Keep in mind that even frequently used software does not necessarily mean it has to be part of the boot-up sequence. Most if not all software works just fine if you load them up after the computer has loaded.

Check the health status of your hard drive

A hard drive which is on its last legs (failing) can significantly slow down your computer and put your computer at risk of losing all its files. Hard drives are mechanical and like everything else mechanical will fail eventually, so keep an eye you’re your hard drives health often.Run the Windows hard disk error checking tool to ensure your hard drive is in a 100% healthy working order state.

Clean up your hard drive

Check that your hard disk drive (C: ) has at least 1gb of free space. This provides the require space for your computer to create a swap file and use as virtual memory. This provides your computer the ability to load and run software at a quicker pace than a hard drive at full capacity. Remove any temporary files, check your download folder and get rid of anything in there that you no longer need. Also remove any software programs which you have not used in the last 6 months.

Each time you run computer software, they each all leave behind a few files like temporary settings on your hard drive. They accumulate each and every time you run software and accumulate in multiples with more software being run. Deleting these temporary files can help improve computer performance because your hard drive has more space to be used as virtual memory.

As a first task to cleaning up your hard drive, I would strongly suggest using the Windows Disk Cleanup utility to locate and delete all temporary files and other such files no longer needed on the computer to help fix and speed up your slow computer.

The Disk Cleanup tool is the first step to removing every file in the temporary files folder, but it does not get rid of every file from there. So once you are done with Disk Cleanup, you should delete the temporary files manually. To do this, open Start menu and type %temp% in the Search field. Press Enter and a Temp folder should open. From here, select all the files and remove them. If they end up in your recycle bin, don’t forget to empty it out.

Available hard drive space is the amount of space available to Windows that it can use to create a swap file with and use as virtual memory. The more hard drive space available, the larger the virtual memory can be and thus allowing for a faster PC. Free space is not only just to install more files or programs.

Defragment your hard disk drive

If you don’t know what defragment means, then it is time to de-fragment your hard drive. Your hard drive is something that likes to be organized, and runs at its best when it is organized or de-fragmented. Having a fragmented hard drive reduces the way your hard drive operates. After de-fragmenting your hard drive, think of it as a spring clean – everything on the hard drive is ordered in a numbered neat fashion, so anything the hard drive needs or wants it can find very quickly because all the files have been ordered in a tidy and neat manner.

Get rid of all the un-used and pointless web browser plug-ins

Your computer has a finite number of resources available to share amongst Windows and all the software programs you want to use so don’t fill your computer up with software for the sake of it. So that means deleting all the crap add-ons and additions to your web browser. Just because they are free doesn’t mean you must have it. They simply clog up your computer, slow down your web browser and can cause a computing disaster down the line.

Un-install Un-used Software Applications

Old software programs on your computer simply clutter it up. Removing these programs can greatly increase the speed of your computer. Have a think about what you frequently use, occasionally use and hardly use. Remove everything that comes under “hardly use”.

Stop using resource hungry bloatware

Bloatware can best be described as software that exists on your PC, but you don’t know or remember how it got there. Bloatware is known for being simply crap and slowing computers down due to their nature of being very resource intensive. A total waste of space and only cause misery to computer users.

Apart from taking up hard drive space, bloatware often finds itself loaded at startup, increasing how long it takes your PC to startup, taking up valuable RAM space, cluttering your system tray, desktop, installed applications, and context menus.

Top 10 Most Common Resource Intensive and Hungry Bloatware:

  1. Outlook
  2. Norton anti-viruses
  3. Adobe Photoshop
  4. Web Browser Toolbars
  5. ITunes
  6. Mozilla Firefox
  7. Nero Burning ROM
  8. Apple QuickTime
  9. Skype
  10. Internet Explorer

Take a look in your All Programs list and see if there is anything in there that looks suspicious.

Run a registry cleaner

Registry cleaners are designed to access the Windows registry (only registry cleaners can do this) and correct any incorrect or un-assigned entries, plus correctly order the entries so it takes Windows less time to seek the registry setting it is looking for. Some examples of registry entries include DLLs, programs, fonts, uninstalled programs, or system information that is out of date. These registry references tend to be be left behind when programs are not correctly removed from the computer or the software uninstaller malfunctions. System crashes can also cause invalid entries being written in the registry.

A really good and powerful Windows registry cleaner not only optimizes the Windows registry, but keeps the rest of the computer system running fast and turns a slow computer into a fast computer. Only the best registry cleaners feature tools that enable them to become more than a registry cleaner. Customer support in your local language and time zone is also crucial, when you need support you need it now and not any later.

For these reasons, I cannot recommend PC Health Advisor enough.

Reboot your Computer

Any time you feel as though your computer is playing up or miss-behaving then it is a sign of your computer requiring a reboot. This is the first step you should take when diagnosing or trying to fix a slow computer. A reboot is also good measure when software programs are not behaving properly like your web browser not opening, Outlook not opening etc. A computer reboot actually solves 99% of slow computer issues, so never overlook a reboot. It is the quickest and easiest solutions to solving any slow computer issues.

In essence, a reboot is like shutting your computer down and switching it back on again. The point of rebooting is to clear the computer from garbage and temporary files and settings, clearing this garbage data can in most cases actually speed up your computer as once it is fully loaded again, it is fresh. It is easy and a quick task, you have nothing to lose and everything to gain.
