Windows 10: My CPU's speed decreased significantly

So I've lust bought a laptop - Dell XPS 13 (9360)/Intel Core i5 7th Gen. The CPU worked properly for about a week, and when I turned my laptop on yesterday, it has become EXTREMELY SLOW. Its base speed is 2.70 GHz, and when I opened Task Manager, its current speed was 0.38 GHz! I don't know why, but with this speed, I can't do almost anything I need to at the moment. How can I make it come back to its base speed like it was before?

Download speed decreased to 0.2mbit (from 6mbit) after upgrade from Win8 to Win10

Hello,

im experiencing very strange problem because download speed after upgrade to Win10 has decreased. Upload speed is still about 20Mbit/sec. I tried following:

• multiple network devices- Primary is LAN adapter, secondary LTE phone. Altough the ping is different and upload speed on LTE phone network is slower, both network connections suffer from very low speed (0.2Mbit). And yes, I tried different pc and
  
• newest drivers installed
• dns cleared
• antivirus uninstalled, no malware found. No improvement in speed either
  
• p2p update redistribution disabled

Before reverting back to Windows81, do you have any suggestions?

 

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
