Got a problem on my other machine, I cant seem to work out the problem.

It connects to the internet via a realtek Ethernet card, thats connected to the cable box. everything ok there...

The problem is the computer wont detect it's there, however when I view it in Device Manager I have to go to "View" -> "Show hidden objects" and then it appears showing no problem.

If i try to uninstall it it says "Unable to install, the pc might need this to boot".

Crying or Very sad then to top it off the pc when I go to "Shut down" it ends up rebooting.... Any help appreciated!

I will try to upgrade the drivers, however the 2nd option will be the last option to try Wink - any other possibilities?

Make sure it's enabled in the bios if it's an onboard one.

Is the reboot of the computer automatic? And it starts going through POST again after the reboot? If so, you should be able to make it BSOD instead of automatically rebooting. You can do this by Right clicking on "My Computer", then go to "Advanced" and into "Start-up and Recovery" then un-check "Automatically Restart". Then go through the same shut down process and instead of automatically rebooting it should give you a blue screen of death, which will give an error message and *may* give a filename of the particular thing that's causing the problem. If so, write down what the error message is and filename and let us know (such as IRQ_NOT_LESS_OR_EQUAL / nv4disp.dll )

Regarding the NIC problem, it could be related to the shutdown issue. But just in case, I'd check in the BIOS to check if it's enabled as whoKnows said. If it is enabled, try disabling it and then going back into Windows and removing it, or into Add/Remove Programs and there should be a Realtek drive to remove unless it's the default Windows one. Also, try going into "Control Panel" and then into "Network Connections" and right click on your card and clicking properties. Then remove everything you can, such as the protocols (you won't be able to remove TCP/IP) and then try to remove it from device manager.

Thanks for the tip's, I'll try these tomorrow. Tho with the Network Connections box there is no connection in there (to my surprise); however when I use the wizard to create a connection it say's there should be another connection active of this type?! odd~

Is there any part of the BIOS i should look at? as I remember I did have a brief look and couldn't find anything relating to the realtek card...

The reboot of the computer is automatic, tho tbh I have a feeling it's to do with the network adapter thats giving the problems...

Sounds like you have a serious registry problem, the state of the registry concerning the NIC is invalid. All physical NICs should be visible in the DM or without a valid driver in the unknown section. Only virtual devices (software layers to physical devices) stay hidden.
Check BIOS, change MAC, move NIC to another slot, reinstall Windows or better boot an OS form a USB-stick or CD thats capable of recognising the NIC, replace NIC. Perhaps there is a DOS diagnostic tool to verify the NIC's proper functioning.

It will depend on the BIOS, however mine for example is under: "Integrated Peripherals" -> "On-board H/W LAN" which to disable the on-board network controller, I'd just set that to disable. Though after re-reading your first post, you mention "ethernet card" so I'm guessing it's not on-board LAN Smile

Are there any errors that appear when you look in Network Connections folder? Maybe after pressing refresh a few times. Also I'd check to make sure the "Network Connections" service isn't disabled and is started. Do this by right click on My Computer, and going to "Manage", then into "Services" and scroll down the list for "Network Connections".

One more thing, when you view the network card under Device Manager, and using Show Hidden Objects, does the name of the Realtek card have "Miniport" at the end of it?

Yes it does have miniport? good / bad? Smile hardware has never been a strong point for me.

I did go though the services bit the other day, all looks ok in that bit.

No error's appear in the network connections dialog, however it doesnt display the local area connection icon... its blank. If i try to create it points out i already have an existing connection...

Ahh, okay that's slightly different. That Realtek card you're seeing isn't really there, it's a virtual device that is created by Windows XP. What you should try is:

1. Open a command prompt (Start->Run->type "cmd" and press ok)
2. Type: set devmgr_show_nonpresent_devices=1
3. Press Enter
4. Then type: devmgmt.msc
5. Press Enter

This should open Device Manager, try to remove the device now. After you've removed it (if you can), turn off the computer and put the NIC card on a different PCI slot and then boot the system up again and go back into Windows and hopefully the card should be picked up properly this time and in a working state, if not there are more things to try.

Sounds promising, really appreciate the help... I'll let you know the outcome tomorrow (unfortunately the offending PC isn't at this location) Smile
