Whenever posting questions on these forums, please give us as much information as possible about the computer. The operating system, processor speed, amount of RAM installed, brand name of the computer (if there is one) and any EXACT error messages that you are seeing. The more information you give us, the better informed our answer will be. Enough of that, back to your question.

Do you mean 'Device Manager', or 'Task Manager' and how are you seeing this 'Network Controller' listing? A 'Network Controller' assists with the Ethernet card's ability to work. Helps with computers that have the ability to be 'servers' or work on networks.

If you're seeing a yellow question-mark next to the 'Network Controller' and it's having conflicts of some sort. Are you having internet/network connection difficulties?

Hope this helps.

Sorry, I'm a little frustrated. I am using XP home, 2.6ghz, 512 ram, Gigabyte board, Radeaon 9600 pro vid card. Games such as Black&White and NASCAR consistently re-boot after a bit of playing. A mouse click or key stroke always sets it off. Yes the 'Network Controller' is yellow in the DEVICE manager. I have no troubles with connecting to internet so maybe that's not the cause of my re-booting. I also have a Linksys router but the only time it seems to lock is on graphics intensive stuff such as games.

Rebooting randomly could be a sign of overheating. It may also be your power supply. I would suggest a 400W or a 450W if you have a lot of peripherals running. To check for overheating, take the cover off and put a house fan blowing in. If that fixes your problem, it is most likely a heat issue.

You should also check to make sure that your vid card has the most current updates

Paul, In Addition To Sageth's Good Suggestion....
by Grif Thomas Forum moderator / October 26, 2003 2:36 AM PST

Some of the problems you are having could be related to conflicts with too many 'unnecessary' programs running in the background. Windows XP can have a lot of programs running in the background that are necessary. Turn some of them off and the computer stops having many of the reboot issues also. Please use the following link and instructions below to shut some of those programs down:

<a href= TARGET=blank>Windows XP Services and Start Up Programs</a>

If you have any questions about which programs to UNCHECK in 'msconfig', post back, or check for yourself at these sites: <a href= TARGET=blank></a> or <a href= TARGET=blank></a>. At this second site, which is probably the most comprehensive, wait for the page to load completely, then scroll down to the 'The Programs' section and click on the 'Full List' link. You should be able to find most programs you have questions about.

And remember, whenever playing games on your computer, it's best to shut down all background programs, including your antivirus program as it can cause slow downs and conflicts.

Hope this helps.

I would ask if this is a home made box, and if the updated motherboard drivers have been installed? That disabled Network Controller is a glaring omission.

A Glaring Omission?
by jenngrayxx / November 27, 2007 11:57 PM PST

Hello Michael,

I have a Dell Inspiron 5100 (2003) and in trying to set up a wireless network this week have found that my network controller has a yellow question mark & over top of that a yellow mark with an exclamation point.

You mentioned in an earlier post that these signs could be a glaring this fix-able? So far Linksys (the wireless PC card manufacturer) and Dell haven't been able to give me a solution.

Thanks in advance,

You've Posted To A Four YEAR Old Thread..

In reply to: A Glaring Omission? I'm not sure the folks from this thread will see your question...

Still, a little more information about your attempts to fix the problem would be helpful..

What operating system is on the computer?

Because the laptop is old, (You're lucky if the laptop is even functioning after 4 years), it could be a network adapter failure... Have you tried updating the wireless and ethernet drivers on the computer? If not, please do.

If you're trying to connect to the network wirelessly, did the wireless connection work before?

Have you recently scanned the computer for viruses and spyware? If so, which tools do you use? Malware can frequently cause issues with your internet connections.

What is a network controller?

Hi as you can see I am a newbee. I have a Toshiba laptop. It wants me to insert the disc that came with my device. Wildows will automatically search the disc for driver software. The computer was set up at Circuit City. I don't have a disc.

Even computer newbies should have the common sense to NOT append their problem to a 4 year old thread about network controllers without even making clear that their problem has something to do with a network controller.

When my son got a Toshiba laptop, it came with all disks, as it should do. But he didn't buy at Circuit City.

You don't tell what you do or did to have Windows asking for the disk. I don't assume it did it right from the start, so something most have changed or happened.

For the moment all you can do:
- see if Circuit City still is able to help you (doubtful, probably)
- contact Toshiba
- find a friend or family member with the right CD and use that

In reply to: Re: newbie

it's possible they put a copy of the Windows disk somewhere at your hard disk. Then all you've got to do is browse to that folder if Windows ask for the disk.

Go and search for folder with a lot of .cab files. That might be it. There's a small chance you can find it in the documentation that came with the laptop.

You've Responded To A 6 Year Old Post??

In reply to: like what?

Since that member hasn't posted in our forum for 6 years, I don't think you'll get much feedback.

Please watch the dates of the threads and posts you're replying to.

Hope this helps.

Light bulbs you shouldn't buy

There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
