Question about Microsoft Computers & Internet

1 Answer

Got a failure at checkpoint USBd on my Dell, followed instructions and changed the boot emulation to No Boot. Fixed my boot up issue but created an issue with my Microsoft Lifecam Cinema and Yahoo Mesenger. After loading YM, if I try to start my cam the whole computer freezes forcing me to do a hard reboot. I uninstalled and re-installed both the webcam and YM 10 with no success, still freezes. Canrun the webcam by itself with no issues and the same with YM. I loaded Skype and have no issues running it with my webcam. Loaded Driver Detective and have updated all drivers. Went into device manager and uninstalled/re-installed all the USB host controllers, again, no success. Even moved the cam to other ports on the back and also the ports on the front of the computer with no success. I do not get any error messages. what am I missing?

    Shiela65,



    First off here is some more info;

    Dell Dimension 8300 with Win XP OS (desktop)

    I read your answer and followed your instruction with the uninstall/re-boot/install etc. After windows loaded the webcam (microsoft lifecam cinema) I went and double checked all the settings on yahoo messenger tobe certain I didnt miss anything. Hit the webcam button and messenger froze immediately. Moved on to Skype, attempted a video call and was able to connect with voice using the lifecam microphone but was unable to load the video. So, using to seperate programs I have been unable to get any webcam imagery. To further check the the integrity of the webcam, I unplugged the Lifecam and rebooted with a Logitech Pro 4000 webcam now plugged into the same USB port that the Lifecam ocuppied. Windows loaded the Logitech cam and the cam was working on its own as does the Lifecam when not being loaded by any messenger or skype. Once again, I tried loading the Logitech using YM and YM froze up immediately.

    So at this point, I have 2 cams that are working properly when they are standing alone, but both cams will not respond to either Skype or YM, freezing both applications. Both the Lifecam and the Logitech cam were found by both programs and they were listed in each drop down menu respectively.

    As I mentioned before, this webcam problem started immediately after I rectified the USBd checkpoint issue with the Dell, Again, I went into the bios and turned the boot emulation to 'no boot" to correct or at the very least work around the checkpoint error. The computer boots up without any problem now but has left me with this aggravating cam issue.

    So, I cant help but think that going into the bios and changing the boot emulation to 'no boot' has created this whole mess.

    Can you look further into this using the new info and maybe come up with another plan? Calling Dell is not very high on my list of fun things to do. This computer is a hand me down so they will not have my name registered to this computer. The service tag on this machine is; 8VQG051.



    Sincerely ,

Friend,
Please follow the link to uninstall and then reinstall the device on your Dell. Remember that reboot is as important as the drivers. You have tried almost everything on your own. Now try out my method.
If by any chance the problem persists then you may like to call up the Dell online help. It is toll free. They do not have any service centers and do every thing online. On the back of the laptop/computer you will find a 7 character number. Just keep it handy while you talk to them. They would know how to deal with your machine.
But, first try my method.

Dell 8400. previous attempts at booting this system have failed at Checkpoint [Writ]. Is this a Hardware or Software problem and have you suggestions for a fix to problem.


It is a Hardware error, and my be associated with the following components.
  1. Memory. Try Memory modules individually, see if you can get the system to boot normally with one or more modules, if you ID a defective one, replace it.
  2. Motherboard. It is possible, that if all combinations of the memory produce change that a failure has occurred in the motherboard. A swollen capacitor is a likely failure.
  3. The hard drive has a cache module, it is possible this memory is defective.
  4. The Processor (Least likely as they almost never fail.)

My dell dimension 8400 bios a03 fails to bootup and displays this alert on the screen: Many attempts to boot the system have failed at checkpoint [Ithr]. how can i recover from this?


You need to reset your bios settings. Open your case and remove the cmos battery for 10 minutes. Caution: unplug all ac plugs before you open your case. put the battery back in and turn it on you should see an error message saying: you need to set system time and date. If you see this then you have successfully reset your bios settings and the defaults should load up. follow the instructions to change your time and date settings and save. reboot and hopefully you can boot up. I hope this works.

Motherboard


Hi,
One of the greatest factor in intermittent shutdowns is because of heat issues. try to check the fans if they are all spinning. if all fan's are ok then you only need to replace the motherboard. here's a manual that might come in handy http://support.dell.com/support/edocs/systems/dim5100/en/sm/index.htm

Hope this helps.
