Internet connects only to Google and YouTube

[xgaming.planet]

Hi there,
some days ago I noticed that I could only connect to Google and YouTube on my PC. The other sites or programs that needed Internet didn't work. I don't think the problem is from Chrome, 'cause Internet Explorer has the same issue and I never really use Explorer. My PC uses an Ethernet cable, which connects to the router. The router itself connects to an Optical Fiber Router, which I got from my ISP when they installed Optical Fiber in my house. Now, the interesting fact is that other devices connected to the Internet through Wi-Fi have no problem with the Internet, at all, so the problem must be from the PC. I googled it and tried different methods.
Some of them are:
-Disabling WMM from Network Admin Panel (192.168.0.1);
-Running an AdwCleaner and ComboFix scan;
-in the CMD, some network resets with /netsh ... and /int ... as I found on one YouTube video;
-changing the DNS in Network and Sharing Center->Properties->IPv4;
The DNS method worked, but only after restarting my PC and held for some hours, until the problem came back. Tried contacting my ISP, they said it isn't their problem, 'cause the Internet works on other devices.

Here are some of my specs ^-^:
-ISP: Rds&RCS, Romania;
-Windows 7 Ultimate Service Pack 1 64-bit;
-Intel Core i3 2120 CPU 3.30ghz;
-My router: N 300Mbps TP-LINK TL-WR841N;
-NVidia GTX 960 2GB;
-8 GB RAM;
-GPU MSI MS-7740;

If you need other details feel free to ask :3

Well it sounds like it has something to do with DNS. Try the 'ipconfig/flushdns' command.

It works, but only after a PC restart, and only for a few hours. Other ideas of solutions?

EDIT: Found out that I don't have to change the DNS to get back the Internet after I can't acces other sites anymore. I just have to restart the PC, and for some hours, the Internet will work good. The question is, how do I get a permanent fix?

im assuming all your other devices connecting to the same modem/router is perfectly normal. and nobody fooled around with the firewall settings in the router either. and your PCs firewall have not been touched. so .. just run this following command "netsh winsock reset". in short, this command gives your device a clean slate on anything regarding the internet.
