I have run into what I believe is the same problem with my daughter's Dimension 4600 PC.  Everything works fine until she tries to connect to the internet.  You can hear the modem get a dial tone when first connecting up, dial the number of the ISP, and then work to establish the connection.  All this is audible from the modem's speaker.  Then the words "Verifying Username and Password" appear in the dial-up login dialog box.  and the modem noise and then white noise/pink noise stops.  Then within about 3 - 5 seconds, a blue screen appears and the included error message shows up. 

Is that exactly what you are experiencing?  Does your PC work fine otherwise?  If so, there are a number of things you may need to do. 

First, you may want to remove the memory cards from your PC, boot it up, then shut it down, reinstall the memory, start the PC back up, and reinstall the modem driver.  There is also a modem diagnostic, called Modem Helper, which you can run from your PC or from the Dell Resource CD.  If these ideas don't work and you have access to another PC which can get onto the internet, I'd try the Dell Chat resource at Dell Product Support.  it's a free, on-line, real-time dialogue with Dell technicians.  Perhaps one of them can help you resolve your issue(s).

Best of Luck!

if that is a blue screen, you need to be specific.coz almost of the blue screen that we are getting in windows will have a memory dump.you can determine what's causing the problem by looking at a stop error code 0x0000000.....(this is the format).if you think it's the modem then you should have this error message BAD POOL CALLER...if it is then it's your modem that's causing the problem.

I'm having this same problem...sort of. My computer is a Dimension 3000 and I've had it about two or three months. This is my first time getting cable for a computer. I went through Time Warner. They came and hooked it up with safe mode and had the cable plugged into the back of the computer when I tried to start my computer in normal mode with the cable plugged in I also got the what techies may call "The Blue Screen of Death" where it talks about the memory dump in process and memory dump complete right after. I also get a IRQI_NOT_LESS_OR_EQUAL at the top of the blue screen. When I unplug the cable from the back of my computer and then restart the computer it comes up fine. My roommate got my computer to get on the internet  (not sure how just yet) but I went to restart it because I made my roommate a user account and I wanted to see if it worked and I went to log on and I got the blue screen again and haven't been able to log back onto the internet yet without the blue screen. Also, when the cable is unplugged and it logs into the computer normally as soon as I plug the cable back into my computer the blue screen will pop up.

Based on the information you included in your message, it almost seems as though the Time-Warner guys either caused, or did not rememdy an IRQ conflict; that is, more than one device is using the same "COM" port or address at the same time. When you unplug the cable/device, you resolve the conflict and you can restart the computer and use it without getting the BSOD (blue screen of death). You also could have another problem, since your roommate can use your PC to access the internet, but you can't - - same machine, different accounts - - subtle differences in the registry. Before doing anything else, try contact Dell through their new on-line chat service. It's a real-time, on-line discussion with a Dell Technician who works with you to resolve your problem. You may have to use another PC, or you can try logging into your PC and getting on-line through your roommate's gueat account. This would be the best way, because you'd be working directly with your PC. You might also check (using the Device Manager in Windows Control Panel > Performance and Maintenance > System > Hardware; and see which IRQs are being used by which devices t try and identify any conflicts. If you don't feel comfortable doing this, perhaps you can enlist the aid of a friend or computer savvy acquaintance. Whatever you do, you do not want to change any settings you are unsure of. If any of these things don't help you, try the next step (below).

Have you checked you PC for spyware, adware, or other trojans? Any of these attacks on your PC can corrupt registry keys and/or cause memory handler conflicts. If not, download (you'll probably have to use someone else's PC) and copy to a CD or memory stick, Ad-Aware SE, Spybot Search and Destroy, Microsoft Anti-Spyware, and Grisoft's AVG 7 anti-virus program. These are all free programs. As soon as you can, install them on your PC and run them to check for and remove, if necessary, any "nasties" from your PC. These programs won't cause the installation issues and other problems you can run into with Norton and McAfee products, and they work extremely well. I'd also make sure you've installed a good firewall (Zone Alarm, also free) to block any attacks from malicious sites. After you've run all these programs and installed a firewall, try hooking back up to the internet. If you still receive a BSOD, you may have to completely back up your hard drive (so you save any wanted data files or information) and then start from scratch, that is, delete your OS and all other programs, format the hard drive, and reload everything.

Good Luck.

My roommate somehow got on my computer not on his guest account but with my account. I tried making him a guest account since the internet was working and we're waiting to buy a router. After I tried to restart my computer it went to the BSOD again. I'll try your recommendations. My roommate and I together know a decent amount about some problems. Thank you and we'll try your suggestion. I'll let you know how it goes. 

One more thing my computer lets me get on the internet if I'm in Safe Mode with Network Connections.

The fact that your roommate got onto the Internet on your account is a good thing. Did he use a regular dial-up account? If so, then you can know for sure, that your conflict is network-based, since cable and wireless (broadband) use the network adaptor in your PC. In that case, you'll need to do some "network devices" trouble-shooting. Additionally, your Time-Warner account may more likely be a software-related issue, rather than a hardware or solely an IRQ-based problem. The software for the TW equipment and there network may be causing the problem.

On one of Dell's Customer Service website pages, they discuss the problem(s) caused with installation of SBC Yahoo DSL on some systems. I'd look up that site and see what they have to say. Could be the problem is nearly identical.

Have a good one!

My roommate got on using the way he was initially intended to but we're not really sure how we got it to work. The blue screen error I get is:

A problem has been detected and Windows has been shut down to prevent damage to your computer.

DRIVER_IRQL_NOT_LESS_OR_EQUAL

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps.

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufactuer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Technical Information:

***STOP: 0x000000D1 (0x0000000B, 0x00000002, 0x00000000, 0xf0626C08)

*** tcpip.sys - Address F0626C08 base at F05EE00, DateStamp 41107ecf

Beginning dump of physical memory

Physical memory dump complete

Contact your system administrator or technical support group for further assistance.

Okay; It looks to me, though I am not sure (not quite THAT advanced in computer stuff) - - that based on your error message, that you have a conflict in the memory handler; the portion of which may involve memory allocated to tcpip.sys. That is why you get a BSOD and the physical memory dump. Then the PC probably reboots on its own after timing out and you're A-O.K. unless you try to again reconnect to the internet via broadband. I would be willing to bet that you're not going to resolve this problem without removing the corrupted files which allocate certain portions of memory to the processes involved. To do this, you will need to "nuke" your hard drive and start over. Perhaps, before you take such a drastic step, there's someone else out there who reads this, who might have a suggestion, but I don't think that will solve the problem. Inserting the Windows Resource CD and repairing the OS installation WILL NOT work; you'll just temporarily band-aid the issue (if it works at all) and end up getting the blue screen again down the line. Additionally, I don't believe System Restore will help you either, but you might try going back to a Restore Point dated prior to the Time-Warner installation.

Before you format your hard drive and start over, be sure to copy any files you want to keep. Additionally, download and install (flash) the latest bios for your 3000 BEFORE you delete and re-install the OS and other programs. If you're using Windows Xp, install Service Pack 2 immediately after you install Xp. You'll also want to have downloaded all the latest drivers and upgrades from the Dell Support > Downloads site to install on your PC after you install the OS, but before installing all the other software programs you desire. The last thing you should install is the Time Warner broadband setup. If you're not sure you have any conflicts resolved before re-installing it, WAIT. You should never have to install or run this type of program from Safe Mode. If you do, there's an inherent problem which Time-Warner and/or Dell should have identified. Contact Tech Support @ Time-Warner in that case. You're paying for that service.

Hope this helps and good luck!

My roommate uninstalled the NIC and the Modem and then re-installed them and that worked. We un-installed the NIC before but not both the NIC and the Modem. My computer is up and running now and is fully functional. Thank you for all your help.

 

Outstanding!

I am glad that you were able to resolve this conflict so easily.

Take care!
