this might get a little long as I have tried to gather as much information that I possibly can. I have trawled through the internet and many forums to find out which information might be useful.
About a month ago my computer started acting strangely. One day my google chrome just stopped working. However...I was on Skype talking to a friend of mine and the call didn't drop out, neither did steam. A restart of my PC allows me to reconnect to the network, but this begun to happen so frequently that I assumed it was a software related issue and reformatted my PC. This did not fix it. Following that I replaced my motherboard and my cpu and reformatted my pc again,(Unrelated issues) that didn't fix it. I use bit defender antivirus and turning this off does not fix it either. Further, there is multiple other computers, macs and pcs, connected to the very same network and non of them share the issues that this pc is having. I am unable to ping website ips or their web addresses and I am also unable to connect to my router via 192.168.0.1. I am able to connect to the router from other pcs. I have hard reset the router entirely and have tried switching ethernet cables with my girlfriends pc which is sitting 2 ft from mine. I have tried connecting to this network via the wireless card in my pc and via ethernet. Both of which have fully updated drivers. Might be worth adding that I have also tried many different web browsers. Chrome, mozilla, opera.
Please lend me a hand!
