I have a bunch of PC's here in our computer shop
Asus mobo P5SD2-VM
1gb Kingston RAM
Core2duo 2.9ghz processor
It was a WinXP before but i've installed Win7 on it since i'm planning to sell it.
Everything went fine except for the LAN. Nothing happens when i connect the RJ45 lan cable. Even the LAN light doesn't make any sign that it is connected to a network.
what i did is, to check whether the Lan cable is the defective one so i plugged that Lan cable to my laptop and it does have connection and i can browse the internet.
I also check under the Network and sharing center if the LAN device is disable but it's not.
Then i get another set of Desktop and reformat it also with Win7.
This time after i've installed win7 on it, the LAN on the latter's desktop is working fine not like the first one.
I'm thinking that maybe it's all about how i installed the OS. because when i installed on the 2nd desktop, the Lan cable is attached on the machine. does it make any difference when you install OS with Lan cable connected and without Lan cable connected?
another thing i've noticed in the first desktop is when i switch on its AVR, there is no LAN light compared to the second desktop which LAN automatically lits when i switch on the AVR before actually switching on the Desktop.
Is there any other solutions to make that LAN work?
I also tried to remove the CMOS on the first desktop for a minute then return it then after booting i tried to uninstall the LAN in the device manager then re-install it then restart the machine again but still its LAN is not working even if it says that SiS191 Ethernet Controller is successfully installed. and that the device is working properly and has an updated driver.
Hope someone help me with this one.
