Anyone good with computers?.having problems.....

Ok so I have a new laptop, only had it for about 2 months and its great, the internet is usually soo fast...but lately its been deteriorating.....
At first it just wouldnt connect to the itunes store, said there was no connection, when it really was connected and the internet was working fine..
Then it was hotmail. Wouldnt open the page, again it says theres no connection, but when I click on the button that says diagnose problems, it reckons everythings fine!!
Then facebook, pictures wont show up (some pics on HF arnt showing up either)
Now DeviantArt and Photobucket have gone spastic, can't use those either cause the page is all wrecked..

Anyone have any ideas? Its getting really annoying not being able to use hotmail, fb, DA, pb etc etc...

Oh and I have antivirus stuff installed and it says everythings fine..

This is probably not the best place to be asking about computer problems but hey I thought i'd try it haha

Try empting Temp.Files and cleaning out the cookies.

Also try double clicking on my computer, right click drive C
Left click properties click tools tab. Click error checking
Check the box to auto fix errors. Click ok. It will tell you
An error check is scheduled next time your computer starts

Restart and let it check for errors.

Thanks!
Its decided to work now for some reason but i'll do that anyway

I have sometimes have problems like that and I think its the internet servers problem rather than yours. You can still be connected to the net, but if they aren't working at their end stuff isn't coming through. Sometimes if you disconnect and reconnect it fixes, but otherwise you sort of have to wait for your server to pull it together.

I know yahoo gives me fits sometimes I like the older version
And they are pushing their new format and it changes on its own
Sometimes and I have to keep changing it back.

But also if you have IE, just restarting your computer will most
Times correct the connection problems.

I run IE browser. All the security updates and other updates
Probably are larger than the original browser program. Right now
I am using IE 8 web browser.

You could also have programs that are conflicting with each other
Over control of which program should do this or that.
