hey,
the connection tht i am using is a standard ADSL. And about the reset hole u said on the back of the modem, i already tried tht. i did reset my modem and restored it to factory settings. tht did not solve the problem. and regarding the data transfer between the laptop and my pc i have tried in both ways through the LAN cable alone and router too, i have got system hangs in both the ways. And i forgot to tell u one more thing, this hang dissappears once i restart my system and after tht when i do data transfer nothing happens. similarly when i am using internet also "hang" occurs randomly at any time, but once i restart my system it wont hang again. but when i start it again from OFF it may hang again.
and about the infections i have already installed malware bytes in my system and checked for malwares, nothing was found. i am using avast 5.0 free antivirus. besides this i have spybot for tracing out spywares and firewall protecting my system.
my system is little older. it has has been one and half years since i bought it.
and my system configuration is,
processor - intel core 2 duo with 2.66Ghz
RAM - 2GB
motherboard- MSI
hard disk - 250GB
can anyone help me to solve this problem??
