Lately, my computer has had trouble connecting to the internet. I'm completely unable to do any work I need to do, etc. This has gone on for 2 weeks. Occasionally, it will work for about 3 minutes but then stops working again. My computer is a desktop PC and not a laptop.
Here's what I've gathered from tampering with it:
My computer cannot connect to a wired or unwired connection (I think)
My computer does not display a yellow warning sign when it's unable to connect.
The main error I am receiving is 'server DNS address cannot be found'.
It says I am connected without any problems when I get the above error. When it says I am connected my browser and internet are not working.
So, I don't really know what to do because it says I'm connected. Though, I suppose this final point might help answers: other devices are able to connect completely fine.
Is there any way to fix my problem? Thanks.

Update:
My internet is now functional for about 5 minutes after I restart my computer. It then goes strange, and gives me a 'Server DNS Adress could not be found' error. The troubleshooter is not able to fix it. Does anyone have any ideas?
What operating system is your computer using? You can manually configure it to use, say Google's DNS: Configure your network settings to use Google Public DNS. After that, you really should scan your computer for malware, as some sorts mess up your network settings as one of the bad things they do.

It's worth using a second malware scanner too - Malwarebytes is a popular and fairly effective one. – Andrew Morton – 2016-09-30T17:49:38.883
Have you tried another browser? – DavidPostill – 2016-10-03T21:11:03.830
Yes, I have tried Firefox and Microsoft edge as well as google chrome – Martin Cann – 2016-10-04T06:07:56.810
@DavidPostill I provided an update edit regarding the stage I have reached. – Martin Cann – 2016-10-04T06:13:32.427
@MartinCann When your computer can reach the Internet, is there a value in the "Default Gateway" field as shown in
ipconfig /all
? – Andrew Morton – 2016-10-04T18:10:27.017In the default gateway field there are only 2 colons following the colon after the line of dots, no numbers. @AndrewMorton – Martin Cann – 2016-10-05T06:20:22.273
@MartinCann If you know the IP address of your router on the internal network (from what I can see it is probably 192.168.1.254) then you can manually set the "Default Gateway" to that. – Andrew Morton – 2016-10-05T10:05:26.657
How do I find that out? And how could I set it? – Martin Cann – 2016-10-05T15:13:16.287
@MartinCann If your router has a configuration page that you access through a browser, the IP address is very likely to be in the address bar in the browser. – Andrew Morton – 2016-10-10T08:01:50.780
