Dell Inspiron 15 3558 SLOW

i am also using Inspiron 3558. Just three days purchased. Facing the problem of lagging. The letter shows up slower than my typing and when i scrolling the mouse, it lags from time to time. Not smooth. 

i am very disappointing with its performance. 

What is really going on? 

my spec is core i5-5200U cpu @ 2.20GHz,  4 G ram.

Hi Lee KWAN :emotion-2:

Your brand new computer should be lightning fast!

I'd suggest you check for latest windows updates are installed or failed. At left bottom of taskbar, click on windows icon, click on Settings,Update & security > Windows Update, and then select Check for updates. Install any available updates and restart your PC if required.

You can click on Advanced Options[windows update settings], and then View Your Updates History. Do you see any failed windows updates?

Other people are having problems with this laptop as well. My system is fully updated. I had to disable a lot of Windows 10 features to make it a bit faster. Things like disabling Cortana and animations help. I don't understand why a brand new laptop with decent specs is so slow.

Other things:

4G is a bare minimum -- you'd be better off with 8 unless you have a 32-bit version of Windows.

The spinning hard drive (vs. a solid state drive) is another bottleneck.

If the system shipped with McAfee/Intel Internet Security, getting rid of that in favor of the MS defender is another big performance booster.

I'd also suggest you download free version of Malwarebytes/ Anti-Malware, and then run it. Malwarebytes is the best for getting rid of nasty malwares which will slow down the system.

Download free version of CCleaner, and then run it. CCleaner should help speed up your computer. I'd suggest you first click on cleaner, registry, and then tools. In startups, disable any programs that might be slowing down your system.

Hi LEE

I'm 100% in agreement with ejn63. McAfee/Internet Security and other top antivirus software take your money and at the same time slow down your system. All of them have their components in the Startups, Registry and web browser which slow down the system. I'd suggest you use the antivirus software (Windows Defender) which already is on the system. It's free, good for fighting viruses and most importantly it won't slow down the system.

When the computer is running slow or crashing a lot, use the Processes tab in task manager to identify which programs are consuming more memory, disk and network in real time. Please click on link below, hopefully it will be of help to you.

Disable some of programs in Startup, especially McAfee or any other antivirus programs.

Run the troubleshooting tools on system:

1. Type Troubleshooting Control Panel onto the [Cortana] search box, click view all, and then windows update. Run other troubleshooting tools as picture below:

If you play a lot of games then I suggest you download the NVidia driver from Dell Product Support page or look for latest NVidia driver from the link below:

After you update BIOS then I suggest updating Chipset and Video drivers. Please update drivers one by one or installation order.
