Why is your PC slow all of a sudden?

Answer 1

Lack of resources: CPU [cycles], RAM, Disk Space.

If a new program is installed [intentionally, or no] Or, if a new process is started [intentionally, or no] they will use up resources. And when one or more of the resources become critically low, the performance of your PC degrades quickly.

When you experience sudden computer slow downs, it's highly likely that your computer got infected. First of all scan your computer with up-to-date antivirus and antispyware software. If nothing is found and you are sure that there are no infections, try the following:

# Remove all the big files from your desktop

# If your hard disk is full get some external usb hard disk and use it to store large files, like movies, music and pictures

# Remove temporary files and other junk files # Defragment your hard drive # Scan your PC for registry errors

Slow makes ofcourse big ressources programs and startup programs... use TuneUp utilities and Auslogics Disk Defrag.

Answer 3

This happens when you're pushing to the limit of your processor, RAM etc.

It happens very easily if you multi-task to much, meaning if you run too many programs at once. Or sometimes one single game can eat up a lot of resources especially the RAM and if it is minimized but of ended, it will surely slow down your computer.

Your computer has become slow most probably you have not cleaned Windows junk, borwser junk and the registry errors. It is also helpful to add RAM, defrag disk, remove unnecessary programs from start up. Using a good PC optimizer and reg cleaner like RegInOut is good to boost computer speed.

Answer 5

You might have too much saved on your hard drive. As well, a high amount of Temporary Files from Browsers can slow the PC performance. Malware and Spyware can also slow your machine.

If you are an adult (otherwise, ask your parents first), you could download two free programs (they are recommended on PC Forums). One is called Malawarebytes and the other is called CCleaner. Malawarebytes is straightforward; it simply removes malware. CCleaner, though, has some settings that can wreck a PC if you don't know exactly what you are doing. I recommend looking at BOTH tabs first. UNcheck everything except Temporary Files under each Browser for your first time using the program. Click Analyse first, so you can see exactly what the program wants to do... then, you can click Clean.

As you learn the CCleaner program, you can also check Cookies. The first time, again click Analyse... and then, on the left, click Options so you can go through the cookies and save the ones you want. Saving moves the cookie from the Left box to the Right box. After saving the ones you want, you simply click Clean.

NOTE: The programs named make permanent changes or deletions. Read about and learn the programs first before running them on your computer.
