My PC Slows Down On Speed, WHY And WHAT To Do?

programmerman2First of all, let me please, say this: WE get supplied with NEW technology (commercial way…) without getting any advice on How-To use it, that is MY personal complain about it! In the 21st Century this SHOULD be anyway the case, the problems are known since ages and the manufacturers SHOULD provide to the customers a comprehensible guide ONLINE (less costs than a printed version…) about how customers have to deal with slowing down PC’s and BEST protection for Cyber-Security issues, WE are NOT living anymore in the Middle-Ages 😉 In the 21st Century WE MUST go for Proactive-THINKing and that is ALSO a RESPONSIBILITY for the manufacturers as:

===> WE are ALL responsible for a more secure internet!!! <===

SO… Sorry, this had to get said as WE have ALL to work more together as WE are using Social-Media as well, remember the word SOCIAL in it! Let us go now for it to explain the possibilities (there are several…) for a slow PC

  • Infected PC through Malware (an online Check will reveal mostly…)
  • Slowing down PC because of NO MAINTENANCE of it!
    • WE will discuss this in the sections below, step by step with different programs to clean the PC.
  • NOT enough space left on the hard disk (hard disk is full!!!)
  • Press simultaneously the “Windows logo Key” and the “letter [E]“.
    • ONLY way is to buy a NEW one, copy the existing stuff from the old one to the new one…
  • NOT enough Memory available!
  • PC needs long time to START:
    • Check YOUR START-UP programs… ONLY for advanced users!!!

Important notice: to know the reason WHY a PC is slowing down, a few questions need to get asked to find the right solution, follow the step-by-step guide below, please… Some ore necessary in case of YOU can’t resolve YOUR problem with the proposed FREEWARE (this could be possible also…) to post on internet help forums

ruotadentata2architet01But first WE will go for Praxis with different FREEWARE tools, such as (download them, please):

WE will see, by using the above mentioned FREEWARE tools, that NONE of them can do the job ALONE, YOU will see this later… YOU will see ALSO, that after having used them ALL that YOUR PC will have accelerated for good!

*******************************************************************************************************************************  VERY IMPORTANT: make sure that YOU have made an UPDATE of YOUR OS before any changes!!!



1st Step To Know: WHAT OS is Installed?

From my year long experience, most people even don’t know what “Operating System” (OS) and how much Memory is installed, NOR the size of the hard disk, here an easy way to find it out:

Press simultaneously the “Windows logo Key” and the “Pause Key [Break]”.

Windows Key+Pause


YOU will see then a pop-up window showing ALL the necessary information, similar to the screenshot below…

2nd Step: Delete The Browser Cache And The Browser History

About the Browser Cache

ruotadentata2architet01[START Text from New York University] In order to speed up web browsing, browsers are designed to download web pages and store them on your computer in an area called the cache (pronounced cash). When you visit the same page for a second time, the browser speeds up the display time by loading the pages locally from the cache instead of downloading everything again. This sometimes results in less than current versions of web pages being displayed, along with problems on registration and authentication pages.

Over time, this process may actually begin to slow down your browser as large amounts of data are saved to your hard drive. A cache does not empty itself and anyone who gains access to your computer can tell from these files what websites you have visited. To make matters worse, this caching is not limited to pages, but can also include login IDs, passwords, banking information, and other sensitive information.

Clearing your cache can significantly improve the speed and performance of your browser and ensures that anyone who uses the same computer and browser after you (particularly on public computers) will not see your private information.

===> It’s a good habit to clear your cache from time to time.  <=== [END Text from New York University]



Use Freeware Tools To Clean Your PC: 1. CCleaner

As described already WE will try out different FREEWARE tools, which are mostly well known over the years to clean our PC, WE will start with CCleaner, check below for download link, please:

Download the program, install it and let it scan YOUR PC, here below some help:



Above screenshot shows (after scanning) 41, 4MB of unnecessary stuff could get removed and deleted


As YOU might have seen on the left hand side navigation of the program, there is also a button “Registry“. It is possible to scan ALSO the “Registry” and to delete orphan entries, do so by clicking that button, check screenshot below…




Use Freeware Tools To Clean Your PC: 2. Sweepi

As mentioned above, WE will use different FREE programs one after each other to find out about the performance of each one and ALSO to maximize the cleaning. Of course I know it already, BUT YOU should find it out as well as ALSO this will convince some hardliners that CCleaner isn’t the best existing program and that one program alone isn’t enough for a deep cleaning of the PC!

So, first download the program at following address ===> Sweepi <=== and install it! Launch the scan and wait till YOU will see the below result.


Sweepi scanning


The below window will get displayed now. Click on the button “Reboot“. The important about this action is that the “index.dat” files will get deleted and overwritten


Sweepi final stage


Conclusion: CCleaner found  41, 4MB of unnecessary stuff and NOW after the scan of CCleaner, Sweepi found STILL 438MB!!! Sweepi can do actually even more, check here ===> http://www.sweepi.com/index.php/tools/ <===


3d Step: Defragmentation Of The Harddisk

What is “Fragmentation” and WHY is “Defragmentation” A MUST?

ruotadentata2architet01[Start TEXT from Microsoft] Disk defragmentation is the process of consolidating fragmented data on a volume (such as a hard disk or a storage device) so it will work more efficiently.

Fragmentation happens to a volume over time as you save, change, or delete files. The changes that you save to a file are often stored in a different place on the volume than the original file. This doesn’t change where the file appears in Windows—only where the bits of information that make up the file are stored on the actual volume. Over time, both the file and the volume itself become fragmented, and your computer slows down as it has to look in different places to open a single file. [END TEXT from Microsoft]

Windows PC’s have a FREE build in “Disk Defragmenter“, check below, please:

In OUR example below, WE will use the FREEiObit SmartDefrag” program…


fragmented HardDisk (2.5%)

As YOU can see there are a lot of “red squares” shown, that is fragmented space, in this case: it took about 2.48%, a lot! Defragmentation is required by +/- 1% of fragmentation!


Defragmented HardDisk

After defragmentation the “red squares“, the fragmention, have disappeared and the hard disk is now ONLY on 0.73%, acceptable!

WE will STOP here, there is actually even more, BUT WE will discuss this in another post; such as Anti-Spyware and Anti-Malware Check! With the proposed programs here YOU will be able to make YOUR PC running more quick anyway…

 OK, I know, YOU are curious 😉 SO… For those who will straight go further already NOW, please check the following links:
