Victim: “My computer is loading EVERYTHING very slowly, yet i clean every part i can: ‘Disk Cleanup;’ temp files; under Document & settings – Local Settings – then Internet temp files; i even defragment once a week. Yet even bringing up ‘My Computer,’ causes the ‘search light’ to try to find files (about 30 seconds later, it does). I’ve checked for viruses and adware and have none (under AOL’s system). Is there something i’m not doing or that needs to be cleaned?”
Did you ever encounter such issues? Your computer always runs fast? Or it moves slowly like a snail? If your computer moves slower and slower, have you ever thought about the reason? This post will give some common reasons that may cause your slow PC.
1. Too many add-ons on your browser.
Not all browser extensions are created for good. “People often assume a slow computer is because of a virus, but a lot of time it’ll be a browser add-on or plugin bundled with a free software download,” Silverman says. These add-ons may proclaim themselves popup blockers or search protectors, but they’re actually browser adware that can slow your computer down by downloading ads and popping up ads every time you open your browser.
2. Too many startup programs
Newly downloaded programs often try to weasel their way into your Startup menu (Windows) or Login Items (Mac). If you didn’t uncheck the box for that permission, you could have dozens of unnecessary programs vying to be ready and running as soon as your computer boots up (as if that’s happening any time soon).
While some programs – such as antivirus and firewall software – should be allowed to run from startup, others – such as iTunes or Microsoft Office – could quite easily stay closed until you actually need to access a file from their digital depths.
3. Too many background programs running on your computer
Remove or disable any startup programs that automatically start each time the computer boots. If you you have a security utility, malware and spyware protection program or an antivirus scanner on the computer, set it up not to scan your computer in the background. Often when these programs begin to scan the computer it can decrease the overall performance of your computer.
4. Your computer is Infected with a Virus or Malware
If it’s not the antivirus, it could be the virus. Viruses, spyware and other malware can slow down your computer as they mess around with everything from hijacking your browser to pushing advertising or phishing sites, to crashing your computer. Today, spyware and other malware is a big cause of many computer problems including a slow computer. Even if an antivirus scanner is installed on the computer we recommend running a malware scan on the computer.
5. Hardware conflicts and outdated drivers
A hardware conflict occurs when two devices try to use the same resource, such as an IRQ or memory address, producing an error. For example, if a hardware device in the computer shares the same IO port as another device that would result in a hardware conflict. In modern day hardware conflicts are less common because by using plug-n-play (PnP) manages each of the hardware devices installed in the computer for the user.
All in all, there are still some reasons that I haven’t listed above. And the reasons I listed above may be the common ones. You can take a reference. And I hope those information can be helpful for you.
