I recently built a new desktop out of mostly new components. When I first built it everything was working great. I got all the drivers installed with no hitches, and setup Wake on Lan/wan and remote access also successfully (so I could access my PC while on vacation). However, as soon as I attempted this while on said vacation... no dice. It had worked before just fine from both my home networks and others. When I returned home I found the mobo had been reset somehow. Once I turned it on, I had to press enter in order to select default setting, like I did when I first installed it. When windows started none of my drivers were recognized, but I restarted and everything came back except my onboard lan; which won't even show up in device manager. I'm using a PCI ethernet controller now so its not a huge deal, but if I could get it to work that would be nice. My biggest problem is that now Windows freezes after a few minutes everytime I boot up. I have to reset, and then it just does it again. For some reason it doesn't do this in safe mode however. I have no idea if this two problems are related.
Things I've tried:
Resetting the mobo (unplugging and removing battery)
reinstalling onboard lan drivers
I've looked for damage from a short on the mobo; haven't found any.
Yes, lan is enable in mobo.
Windows 7 Enterprise 64 bit
Biostar A870u3 mobo (new)
athlon x4 3.2 (new)
8gb gskill ripjaws ram (new)
Nivida 8500 gt (old)
Everything else is old.
So I think I've narrowed the problem down to the nvidia drivers. I noticed the pc didn't freeze at all when in safe mode or when using the s-video port, rather than the dvi to hdmi port I usually use. Also, the majority of the freezing happened while in firefox. If I use internet explore or chrome it rarely freezes at all. Firefox used a nvidia plugin so that may have been the cause; though disabling it had no effect.
Any ideas what to do? I'm using the latest drivers for my card from the nvidia site.
