Hi I have a Inspiron 3543 laptop, i7-5500U 8Gb RAM, Nvidia 840M 2Gb, Win 10 Home
The laptop boots quickly without issues, during normal operation (web browsing, accessing the file system) it just freezes randomly for up to 5-10 minutes a time showing 100% disk usage. There is plenty of disk space it's a 1TB drive I have 900 Gb free! I have done the following things which haven't fixed my problems.
Turned off SuperFetch, turned off all app notifications, turned off BITS.
I have removed all antivirus software from the computer other than Windows Defender.
Installed the latest device drivers from Dell, flashed the BIOS, Chipset, Video Drivers.
Turning off SpeedStep in BIOS improved performance dramatically but the computer still does this.
The BIOS diagnostic tool didn't show up any hardware problems.
Curiously I am able to delay this from happening if I don't access the file system, ie use Windows Explorer. Opening any folders from the desktop instantly causes this problem.
Please help!
