Averatec 6200 Series Laptop
XP Home SP3
Wired NIC - SiS 900-Based PCI Fast Ethernet Adapter
Wireless NIC - 802.11g MiniPCI Wireless Adapter
This laptop is a client's and the problem started with him not being able to boot the machine. One day, it was fine and the next day, nada. The machine wouldn't boot to any Safe Mode or LKGC or normally. Troubleshooting showed that it was hanging up on gagp30kx.sys. It was a hassle but I got that situation resolved. The machine now boots normally and consistently now.
As per the suggestions for fixing the gagp30kx.sys error, I ran CHKDSK from Recovery Console to check disk integrity. Some errors were found and fixed but nothing major. So the hard drive seems to be OK.
Neither network connection will work. Both are enabled. No link light on the wired connection and the wireless connection will not survey wireless networks. I know my wireless network is operational as I am connected to it right now on this computer.
Things I have tried:
1. Uninstalled (via Device Manager) the NICs and reinstalled them.
2. Updated drivers for both (downloaded to a USB flash drive on another machine)
3. For the wired connection, tried 10 different ports on my switch. Switch is a fairly new Dell PowerConnect 2324 24-port switch and I have 8 machines connected to it. None of the other machines are having connectivity issues. Even plugged the misbehaving laptop into a port being used by a known working machine.
4. Used the IP RESET command - netsh int ip reset c:/resetlog.txt.
5. Rebuilt the protocol stack using the "Hard Core" method on this page: http://smokeys.wordpress.com/2008/07/20/how-to-recover-a-really-dead-windows-xp-sp2sp3-tcpip-stack/
Things I have NOT tried:
1. Repair Install. Haven't had much luck with repair installs and therefore don't trust them. Once I got the machine is up and running, I did backup everything on the laptop to an external hard drive. So...I could try a Repair Install but I'd rather see if there's another way to fix the NICs before doing that.
2. Reformat and Reinstall. Don't want to do this unless there is no other option.
3. Did not scan for malware. He has Symantec 360 on the machine, but I can't get updates with no Internet connectivity.
4. Did not (as I don't have one) attach a USB external NIC to see if it would work.
5. Did not (as this is a laptop), physically remove the NICs and install known good ones, which would have been my first step if this were a desktop.
The research I did on gagp30kx.sys referred to Via motherboards several times and that this file, gagp30kx.sys is notorious for failing with Via mobos/chipsets. I can't find the specs on this Averatec to determine if it has a Via motherboard or chipset. The Averatec website didn't have much in the way of support other than a User Guide. Even so, since I have recovered from that error (by replacing gagp30kx.sys), would, or could, a video driver cause problems with NICs? I can't see that it would. The user said that everything was working fine before the crash - no errant behavior, no error messages, no indication of any kind that there was a problem. This, though, is common with gagp3kx.sys failure.
