Thanks Jock1e

PC still up and running but have not tried to run games although a film ran with no problems , so we will hope it is OK now.

Don't know if I should have started a new post but as it relates to this one here goes.

I thought about trying a wireless dongle (adapter)and I have a spare one issued to me from Virgin media it is Netgear wireless N Dual band USB adapter, the router in question is a D-link -G 122 H/ver it already has an adapter stood next to it, as the router is downstairs and PC is up stairs.

My Question is is it even worth trying this?, I'm not very techie and this might be a stupid question but thought Id ask anyway.

Thanks for all attempts to help with this problem. I'm late getting back here as I have been trying to get this internet connection set up via the phone, with the help of Talk Talk technician and brand new router from Talk Talk.He said the problem is between the router to the PC, as phone line and router are OK.

When I look in Lan or high speed internet, there are three items listed (is this right?) they are as follows

1.... 1394 connection disabled, firewalled.1394 net adapter.

2.... Wireless network connection 5 disabled firewalled, RT2550 USB wireless lan card.

3....Wireless connection 2 connected firewalled, 802.11g pci wireless network.

As you can see the connections were called 2,5,7 now they are 2.5 7 has disappeared.

There is also a listing under Personal area network it is as follows,

Bluetooth network connection, disabled firewalled.

The problem still exists PC can run for a few hours then lose the connection, then it can take a couple of hours to get it to connect to internet again.

I don't know if this is of any significance but the problem first started on Facebook on the chat, A message appeared saying "Chat has disconnected", then today my brother (it is his PC) disabled chat on Facebook to see if it would help, he continued on Facebook then decided to enable chat again the PC immediately lost the internet connection. Took 2 hours to get it back online. This is so frustrating as neither of us are computer techies but I know I little more than him and I want to try to help him.
