Don't you hate being the "computer guy" in the group that everyone looks to to fix thier computer. We'll My friend got a hardware upgrade about a week ago (512MB Crucial Ram, Athlon 1.2, Abit KT7A). We'll the problem is the computer seems to lock up quite often. So i took all the cards out and pretty much narrowed it down to his Netgear FA311 Nic as it only locked up when doing internet related stuff (i.e. going to webpages and in irc). Soooo i switched out the NIC with a Realtek, intsalled the drivers and no connection....i tried specifieing the IP and SN Mask and right when i click on IE and tried to go to a page it locked. I checked IRQ's and windows reports no conflicts. He is running Windows 2000 btw. Does anyone have any advice?? Even his mom is pressuring me to get it fixed...grrr. Its like I'm at work or something.
