When I open a webpage, my browser will use 100% cpu, the page will load slowly, video/audio will freeze or sputter and the computer becomes generally unusable. This happens in Chrome, Firefox and Edge. Even the mouse hesitates when moving the cursor.

I've tried everything I can think of aside from a remimage which I really don't want to do and am open to ideas.

  • HP Envy Laptop
  • Win10 pro 64 bit
  • 16gb of ram
  • Nvidia GeForce 940mx
  • Latest drivers for video card (
  • Solid state drive
  • 4 core i7 proc, 2.7ghz

I did a quick procmon capture while loading msnbc in Chrome and there were a bunch of reg queries where the result was 'name not found' but that's the only thing that stuck out. Any help would be appreciated.

  • Run Malwarebytes over it? – davidgo Apr 24 '18 at 4:52
  • Malwarebytes didn't find anything "no threats detected" – Bbb Apr 24 '18 at 22:48
  • Have a look at the CPU temp and frequencies - maybe the CPU is overheating and throttling down? – davidgo Apr 25 '18 at 0:08
  • You may be on to something, I see the temp spike in speed fan when the cpu spikes, but I cannot seem to find a way to control it. I tried Notebook fan control software but that does not support my Hp Envy, do you have any suggestions for manipulating fan speed? – Bbb Apr 25 '18 at 0:58
  • The temp spike could be normal - the CPU is doing rendering work - but do the CPU frequencies go up to 2.7 GHz? – davidgo Apr 25 '18 at 3:56

possible reasons that you have adware in background , you need to cross check your device and uninstall any program you suspect it contain adware also download adware removal , antivirus such as Avast and AVG, can do the job.

  • I have avg and ran Malware bytes with "no threats found" . I don't install hardly anything on this computer and certainly not anything I didn't have a known history with (example is Office or Visual Studio) – Bbb Apr 24 '18 at 22:50
  • lastly uninstall your browser and reinstall it – Malik Ismaeel Apr 25 '18 at 5:44

It's some times related to the Windows 10 Dynamic ticking. Run Command Prompt as Administrator, type the commands below: bcdedit /set useplatformclock false Then type
bcdedit /set disabledynamictick yes Type bcdedit again to check the status.

It also can be related to the Windows 10 network components. download TCP Optimizer and use the "optimal option" https://www.speedguide.net/downloads.php After doing these above, restart your system.
