I recently installed Windows 7 Ultimate on two computers, one is absolutely fine and working perfectly, the other has had some issues and still has a couple.
At first everything worked fine, but then the nvlddmkm.sys failed and meant I couldn't use drivers.
To resolve this I had to do a proper hard drive wipe (not the Windows one) and reinstall.
Now I can't use the network or internet, it has the yellow ! at the bottom.
I've tried diagnostics, they say that I should reset the router (doesn't work) and then that my computer is having trouble resolving my IP address.
After attempting to set my IP many times to the correct one, there was still no success.
I tried using an old network card (3Com 3C905C-TX-M) but found no drivers that would work.
I then tried going back to vista, which had the same network issue so I'm back on 7. Every function of the computer works apart from the internet, and I do already have all the latest nVidia graphics and chipset drivers installed.
It's not an old computer, as you can see from the specs.
Any help is greatly appreciated, thank you,
Simon
