Last night I was messing with my XP2500+ and finally got a stable setting at 12.5x172. This afternoon when I got back from classes, my onboard nic doesn't work. I cant get online at all. I checked the switch, all the cables, and nothing seemed to be the problem. I tried resetting the bios, reinstalling drivers, but that didnt work. I install my Linksys card and everything works mint. The only thing I changed from last night until today was OCing the processor. I can still get on my schools network through it though. Im extremely confused right now. Anyone care to shed some light? Thanks.
