A couple of days ago my desktop PC stopped being able to connect to the internet, this issue first occurred when I turned it on that morning having had no issues the previous night.
While the PC can connect to the router, first through a wireless device and then an ethernet cable, it cannot for some reason access the internet connection. I believe this issue is something to do with the computer itself because I have had no issues using the internet on my laptop and phone at any stage while this issue has been ongoing.
I've tried the ipconfig commands that I've seen recommended on tech support forums for similar issues but they have not yielded any results.
I'd be very grateful for any advice you could give concerning the matter.

when you say you have tried ipconfig commands, what have they shown you? Is your ip address within the range for your router, is your routers ip the default gateway?
Did you install or change any settings around that time which may have caused this to happen, change of proxy settings, messing around with the host file?
When you are connected to the router does it come up and say "no internet access" or does it show everything as normal but your browser doesn't load webpages?

Thanks for replying, the set of commands I've tried is "ipconfig /release", i"pconfig /flush dns", and finally "ipconfig /renew".
Prior to this problem occurring I had not changed any internet settings or downloaded any files for at least a week.
When I am connected to the router it shows "no internet access" underneath the name of the network.
try the commands Jiroz provided, if you can do "ping www.google.com" for example and it works you know it is your computer (browser), if you can't try ping the router itself (ipconfig /all and ping the ip of the default gateway).

I tried pinging "www.google.com", the result was that the host could not be found. When I tried pinging the router's address, all 4 requests timed out with all four packets being lost.

I assume you know your router's password? (this is different to the Wifi-pwd)
Try logging in via your browser to the IP address of the router, and look around in the router ui, especially into anything dhcp related, or towards some kind of blacklist or banned mac addresses.
Edit: of course you also want to check the configuration of your nic, namely the tcp/ip settings. You can manually override whatever IP configuration your router would want to pass on to you via dhcp there, if you set the 'right' wrong things for IP address, subnet mask and default gateway, you will never be able to go online.
edit2: this is a video of doing the tcp/ip thing

No issues with using other laptop and phone via the router so it's not that.

If it starts with 169 you are not connected to anything, check your connection again, try resetting your network card in device manager > Check you are not using a static IP, (assuming windows 7) type "network and" into the start bar, click "network and sharing center", click "Change Adapter settings" right click your, connection wireless or LAN, properties.

Advanced, DNS, Tick Append Primary and Connection specific DNS suffixes, and the check box associated with it.
Edit: Your editting as i type! I clicked quote and you only had the first bit!! lol, at least we can be comforted in knowing that we both came up with the same solutions

On the TCP/IPv4 properties menu, what should I choose as the preferred and alternate DNS servers. When I try to load up chrome now the error is that the DNS look up failed. I've tried disabling my firewall and disabling network prediction as recommended by the error screen.

What you should first do is only try to connect to your router with only one interface instead of having both wireless and ethernet connections active, and then disable the other unused interface. Then do a "repair" on the active network connection and retest.

I've only been using one interface at a time, sorry I should have been more clear with my wording in the OP.

so when you run a simple ipconfig, is it showing that you are getting a valid IP address from the router? You aren't getting an automatic private address, right?

Ahh ok, just ruling something out
I've actually got mine set to my router since then it will automatically use the default ISP DNS server. Although with the issues you are having you should find out what the IP address of your ISP's DNS servers are and put those straight in. You can find out by typing the name of your ISP followed by DNS server into google. They should have it on their website, whoever they are.
Edit: The repair option in windows just resets the network adapter, which I believe he/ she's already tried. Also, I just realised what you were talking about with the DNS servers and also remembered about your laptop and phone....
Set your Primary DNS to your routers IP, if it doesn't work then we can rule that out. What is the error screen you mentioned?

He can contact the router, but no further
Edit: But yet he needs to do an ipconfig to see whats going on.
Out of interest can you try using a different internet browser. You said you tried Chrome, what about IE? Or Firefox if you have it

I just tried pinging the router IP address again, it was successful with no packet loss but there's still no internet connectivity.

None of the three browsers seem to work, the network and sharing centre shows that I'm connected to the router's network but there's no internet access.
Should I post the ipconfig log or pm it to somebody?

The ping to google failed.
