I would suggest doing the following solutions given below.
Restart your modem
If you are using a modem and connected to your Wifi, restarting your modem is the quickest and easiest first thing to do, but note that resetting your modem is different from restarting, just press the power button at the back of your modem and wait for couple of seconds then turn it on again. Also, you may unplug your modem and plug it in again.
Check who's connecting
If you are connected and using your Wifi make sure that there's no other device that is connected, having a lot of devices connected to one internet source will slow down your internet speed.
Clear your browsing history
Go to the Settings of your Safari app, please tap the icon, scroll down and then tap the "Clear History" button. Repeat this on a regular basis to keep your browsing fast.
I hope this helps!

I kept getting the blue screen with Driver Power State Failure error message and then my computer would restart. I found your product and it did not happen any more. I just purchased an anti-virus (kaspersky) and now it is doing it again. It is so frustrating. My computer is only 6 months old. It is a Asus desktop.
