Hi,

I am using Pentium 4 - Windows 2000 SP4 OS - Motorola Cable/Voice Modem Model SBV5120 - Cable Connection.
It gets disconnected in middle of something and my modem link light starts blinking after which i cannot access internet, neither i can ping any site like www.yahoo.com. The only option to get back is to reboot my PC. The problem cannot be with Modem as i am having Telephone line attached and is working perfectly fine. It seems something bothering on my PC due to which it loses internet access. I have already changed by Motherboard which has inbuild Ethernet card (inbuild on Gigabyte Motherboard). I am attaching the HijackThis log for whats running on my PC. I have Macafee installed (without firewall), and AVG AntiSpyware 7.5 software for Spyware. Could somebody please help in analysing the logs and let me know what could be the problem. Its really annoying to reboot the PC. Rebooting the Modem doesnot works. Neither removing the internet cable -
