I have to either restart the computer or unplug the ethernet wire and plug is back again for it to work again. I use a router that link to 2 computer, the other computer is working fine. I am from singapore and using starhub as ISP I have reformatted my computer I have change the ethernet cable I have changed router I have changed modem... Nothing helps.. what should i do?
Run scans for scumware. Your computer may be infected by something that's causing a crash. Check your drivers are up to date. Some of your computer's hardware might be playing up - for example, your power supply may need replaced (happened to me).
Do what McFox said but use a virus scanner called AVG free search it in google and it'll find everything! Also try plugging it into a different Ethernet port! that port may be fried or something
Try this one. I hope it helps. Backup settings (The program will do it for you) before you start fixing. It's a life saver http://www.download3k.com/Install-WinSock-XP-Fix.html http://www.pcworld.com/downloads/file/fid,25701/description.html
Have you contact any friends of yours that using same ISP? Ask them about it. Maybe they had the same problem. Maybe it is because of the internet problem.
If you don't have any malware in your computer and you're 100% positive about that then it has to be a hardware issue. Try getting all recently windows updates and network card drivers.
