Hi,
I have a DH77EB Mobo with a Core-i5 that I've been using in my HTPC for the last few years with no issues. A few weeks ago, my LAN port started acting up, intermittently dropping the connection to the router with the only fix to restart the computer. This would usually happen when woken from sleep. I updated the drivers (a few times) with no success. Over the last few weeks, it's gotten worse; now even after a restart it doesn't always come back, sometimes taking a few restarts to get it working. In addition, sometimes if I just leave it for a few minutes it will reinitialize and come back online. I've tried swapping cables and ports on the router - I'm pretty sure it's a hardware issue. Then, a few days ago, I've noticed that when I do a restart, sometimes the computer shuts down and hangs before powering down completely. Same with a full shut down, sometimes it hangs and won't power down all the way. Next, I've noticed that sometimes I'll power it up and while the fans start spinning, it won't POST or Boot. I need to do a hard reset and power it up again and even then sometimes it won't POST/boot. Once it does boot, and if the internet connection is working, then it works great. Any suggestions? To my knowledge there were no hardware or software changes that precipitated the failures. I know sometimes hardware just gets tired... Is it time for a new mobo?
Thanks in advance,
Ben
