Windows 7: Please Help. Internet dropping out

Hi
This is my second post about this problem as the first had no reply and this problem is driving me crazy.
My internet access will keep dropping out randomly.
i have done several ping tests and to google when the internet drops out it says Request timed out.
it says request timed out when i ping my modem(192.168.1.254) as well when my internet drops out.
I have recently bought a PCI network card from TP-Link (TG-3269) and it has done nothing to solve my problem.
I have reinstalled the drivers countless times.
Changed the cat5 cable once.
Reinstalled windows Once but the problem persists.
Also this problem only started to happen after i moved house.
And when i took it to a store to get fixed they couldn't duplicate the problem so couldn't fix it.
Please help me on this im diverting to playing console games.....

If you're behind a router... that's the only thing you haven't replaced

It could be a line problem, check with your ISP and have them run a line test.

It can't be the ISP's problem because the other computers work fine. And i'm pretty sure im not behind a router but i'll check. Any other suggestions?

It disconnect again like a minute ago. This time when i did the windows 7 troubleshooter thing it actually came up with a problem. DNS isn't responding hope this can help you help me :X

you said "It can't be the ISP's problem because the other computers work fine. And i'm pretty sure im not behind a router..."

in your home, IF more than one computer can connect to the internet you are definitely 'behind a router'.
IF your system specs are correct--the 5200 RC--is a router.

How are you connecting the machine that keeps dropping out? Wireless? or Wired?

the 'DNS not responding' make me think you are wireless--probably to far or too obstructed from router antenna--IF wired...could be a bad cable. (when the connection drops...are the other computers still connected?)

here's a link to the operating manual for your router:

I know for a fact im wired. there is however a wireless network in my home but my PC doesn't use it; thats for the laptops and such. My Modem does have the latest firmware. And yes when my computer drops the other computers are still connected.

OK--so the problem is somewhat narrowed down to your machine only.

possible solutions:
1. IF there is another machine with a wired connection in your home--try connecting to that 'exact' line (move your machine to that location)--if problem persists--then it is probably an issue with your machine.
2.IF problem goes away--is possibly a bad ethernet cable, a bad router port, or possibly a bad or incorrectly connected line filter

Usually that happens when two IPs are the same.. but usually windows will let you know there is a duplicate IP on the network.

What if you tried a static IP address on the computer... that will narrow some of the issues down.

If and only if the dynamic ip server on your router is conflicting with your PC.

Another thing, can you check your firewall... can you shut your firewall off TEMP to see if its staying online or not.

Another thing is check the firewall with your router...I know this may be a long shot but do a Full restore on the routers configuration file... make sure you back it up first because if the flash doesn't work then you can restore your previous settings.


Another... just to narrow some problems down.. can you change the LAN port that is going to your computer and move it to another port. Possible to one that you know is working with another computer.

Ok so im pretty sure its not a bad wire as i've replaced that, i have changed the port this computer uses to a known working one but to no avail. However i did take it once to a local computing shop to get fixed but they couldn't duplicate the problem so was unable to solve the problem.
I would like to try the static IP test but i have no idea on how to do that. Does static IP on this computer just mean that it always has the same IP adress?
