OK, here is some back ground. I am on DSL from AT&T, running windows XP. I have updated all my drivers, with the exception of BIOS which I am leary of doing. Every few hours, at random times my computer just stops responding to the internet. I have to reboot the system and it then logs on fine. I have since moved to another location and it still does the same thing. Sometimes it may be 3 hours other times maybe 6 hours. I reformatted my hard drive, but it still does the same thing. I check my connection when this happens and it tells me that I am connected. The other computer in the house does not do this. I have check my system time and time again for spyware, adware, virus's, etc. I have even disabled my firewall and virus checker just to make sure, but it still does it. Any help would be greatly appreciated and will post any information that is needed to help solve this issue.
