Lan Connection/NIC issue
Posted on 2013-06-03
I have run into an issue that I can't seem to resolve and hope to find someone on here that may be able to point me in a direction I have not tried.
I have a clients computer and he tell me that after a big storm his computer no longer connects to the internet.
After trouble shooting the onboard NIC it does in fact appear to be fried. So I just put in a new PCI Express Gigabit Card. Initially I am getting a link light on the NIC, but I am also getting the "network cable unplugged" error. So I decide to do one of the many steps people have mentioned when trouble shooting this problem. I changed the speed and duplex setting. BAM! It's up! Then about 15 seconds later, it's down again. The only way to get it to link up is to change the speed/duplex setting for the NIC again. Otherwise all you get is a solid status light on the NIC and the same cable unplugged error.
Sometimes after rebooting, it will not even show a link light at all. I go into the device manager and I see a Code 10 error "This device cannot start."
I understand when something doesn't work and it makes it a lot easier to trouble shoot than when something works intermittently because you can eliminate certain causes.
I have tried:
* two different brand new NICs and get the same result.
* a different PCI slot with the same results.
* testing the PSU and it passed.
* swapping out PSU with a new higher wattage one, just in case. No joy either.
This is an older computer.
Acer Aspire M1100
Vista Home - SP2
AMD Athlon Dual Core 2.10GHz
I am wondering if the electrical surge may have just screwed up the motherboard enough that it allows the computer to boot up and function fully in all other aspects other than network access???
I would appreciate any insight you all may have to add to this problem. Thank you.
