Hey guys, Yesterday I dismantled my PC as was having issues with water temps, turned out to be a little dye clogged in my block. I rebuilt it after that, leak tested overnight for about 14 hours (no leaks), then tried to power it up. Was working fine for a few hours, then I plugged in my Ethernet cable, no connection. Ok, checked the other end, that was fine. Checked the port and no activity lights on it... strange.. Opened device manager and no network devices are listed. Checked in BIOS and made sure it wasn't disabled somehow. Specs: Gigabyte Z68XP-UD4 - onboard lan i5-2500k 8GB RAM 2x 5770s I have no idea what the issue may be, I tried clearing the CMOS (removed battery) and no luck. The only thing I can think now is that I somehow damaged it in the rebuild, and its now faulty. Strange that it was only the NIC though. Any suggestions before I take the board out and try to get it replaced? Cheers guys.
