For some reason....after about 30 mins of browsing the internet, if i try to open a page or go to a site the internet connection stops and i have to restart my PC....

What could the problem be???

 

your router dropping connection?

Are you 100% sure that the thing that cures it is a restart?

 

Its not running wireless.....but it does run through the router....

Once restarted, the internet works fine for a while....but then it just stops

 

It doesnt matter that its wireless or not, the router can still drop its connection which will mean no internet until its reconnected, mine does this but luckily only once or twice a week, still annoying though and never worked out why.

Im not saying this is the case with yours but it just sounds like your router dropping connection.

You could try resetting it by turning it off at the wall for 20seconds then back on, might have to wait 5mins for it to reconnect though.

 

Just reset the router.....will see what happens now

 

Just done it again

 

FOOOOOOOOOOOOOOOOOOOOORMAT

 

Its JUST been done.......had 2 X 4MB thingys put in it aswell and a fucking bad boy graphics card

 

id go for the dropping connection id try pinging from cmd prompt type the below

ping -t www.google.co.uk

just let this run in the back ground and if it gets no reply for a few lines then comes back id say its ur ISP and not the network card thats local to the machine

 

fcking routers

Have you got any other way of connecting to the net like a broadband modem(not the old slow things) or something other than that router, then you can see whether or not its actually the router thats your problem.

 

It won't be the router. If the problem rights itself after rebooting the COMPUTER, then the problem can't be with the router (as a hardware problem)

For the problem to be the router, rebooting the computer wouldn't make fuck all difference. You'd need to reboot the router or swap out the LAN cable to a different port. I had a router randomly drop ports - ie my machine would be plugged into LAN 1 and work fine, then one day not work at all. Swapping to LAN 2 would solve the issue.

So it's either a software issue on the PC (problem with the network card or IP assigning) or an ISP problem as t31ryt says.....

EDIT - have you done anything with phone line recently? Have you a microfilter in each socket?

 

Right then.............

The laptops are still running in the other room when the main PC stops working......

SO....i tried to connect on Internet explorer and NOT use Firefox...to which it worked.

SO...I have just uninstalled Firefox and re-installed it.......Lets see what happens...

As said, The laptops have been running fine for 2 hours without dropping..........

 

sounds like the desktop then as abouve if it was the router then bootin the pc wouldnt sort the router.....another thing to try is logon to the router and assighn a stattic IP as instead of relying on DHCP....is the desktop cat 5'd to the router? have u got wirless phones in the house as sometimes they both use channel 11 and that can drop some wireless cards

 

Reinstalled firefox and it is still doing it.....

It has been fine for months...never done this before.....

All i have done is fitted 2 new memory sticks and a new graphics card

Nothing to do with the phoneline as it is Cable...fibre optic

 

Stop saying wireless, hes using a router yes, but hes hard wired into it

 

any ideas peeps

 

hard wired then it MUST be the hardware.....he says the wirless doesnt drop from his laptops SO that only leaves the nic.....if the nic drops its cos its either losing its DHCP address or its just duff...try setting it stattic tiff...u got nowt to lose.

have u looked in device manager TIFF u may have a conflicting IRQ as u said u have only fitted a new g/card they could possibly be sharing the same IRQ???

and beemer boy im only tryin to help if u got nowt constructive to type then dont friggin type!!!!

 

My laptop has been doing the same thing , working fine then grinding to a halt ! it has only been doing it since visiting a few new porn sites . I ran a de frag , and cleanup , downloaded and ran the newest version of ad aware and norton and it all seems ok now .
Seing as i know fook all about computers this information is probably about as usefull as a one legged man in a bum kicking competition but you might have visited the same sites accidently like i did
