One week ago my PC, running Windows XP Home Edition Service Pack 3, stopped connecting to internet. Maybe it all started some weeks ago, when there was difficult connection? - if I booted my PC when the router was already on, I needed to switch off and then on to gain internet connection and access. The PC has 2 connection, one wired and another wireless, and noone works. Tried unplugging wireless USB connection and disabling wired one; then installed a new NIC but nothing changed - no internet connection; so restored previous hardware configuration - onboard lan & wireless USB. Other devices connect to internet without any issues using same router (PCs, smartphones, ...). System tray connection status is always trying to get network address. Ipconfig command reports IP address 0.0.0.0. Tried Microsoft Support methods, run MicrosoftEasyFix50562 and MicrosoftFixit50267 without issue resolution. It seems an issue like one described in post http://www.techspot.com/community/t...cp-wont-start-error-1068-dhcp-afd-sys.182903/, but FRST logs posted yesterday, examined by malware expert in Virus and Malware Removal Forum, don't reveal anything malicious. Can anyone suggest me what to do, possibly without reinstalling o.s., please...?
