All browsers are slow on i7 with Win 8.1

[General Confusion]

Windows 8.1 64 bit Professional
Gigabyte GA-Z97X-UD3H Motherboard
i7 -4790 3.6GHz processor
nVidia GTX 770 graphics card
16GB corsair RAM, DDR3
232 GB SAMSUNG SSD
1TB Secondary hard drive

This is my system. I have cable internet D/L 33MBs. All has been good until recently. Any browser I use takes about 5 seconds to download any new page. I did a speed test and ping and speed are OK. I have turned off Hardware Acceleration in the browsers but it didnt make much difference. I ran malwarebytes, found nothing. Also did a System File Check, all good.

The system boots OK, all other apps/games run well.

I have heard there compatability are issues with the i7 CPU and Win 8.1. I have had/resolved issues with Flash already. Any ideas/suggestions?

sorry, to ask, but you have done the basics of clearing all browser data right? (cookies, cache, history etc)

Try with AV disabled?

Also, what model samsung SSD do you have? There's a known issue with the samsung EVO range that requires a firmware update
