Browsers

Hello.
For about 2 weeks now, all browsers (Chrome, Microsoft Edge, Firefox) on the PC have been slowing down.
All other programs work fine.
Reinstalled Windows but nothing changed

QuadCore Intel Core i3-8100, 3600 MHz (36 x 100)
Intel(R) UHD Graphics 630 (1 GB)
Intel Cannon Lake H310, Intel Coffee Lake-S

Unable to use browser.
With any action, the friezes open the site page for 2-5 seconds and for a long time.

Maybe a problem with iron? For example, the old hdd.

Answer 2

What does the performance monitor say?
IMHO the problem may be in the network.
Check for packet loss to large resources, per 1000 ping requests.
Check the work of dns, try an alternative one, are there friezes when opening resources by ip?
