The monitor icon is missing in Device Manager

Monitor-viewsonc vm2235wm; NVID 8600gt video card; 6750 cpu;
After concluding an update of the software of ms on 09/09/09, restart vista. Boot vista system good to load the monitor says no signal and stops. Vista keeps going with the sounds of startup vista responsible for confirming. A made a forced stop and start in safe mode. Monitor now works. Go to the device, active graphics card Manager - said it was ok. There was no monitor icon in the list. Updated graphics driver while there and rebooted. Still no monitor. Vista restored one week before the problem - same problem. Removing graphics card and initialized using the graphics card integrated and faithful old crt screen and device manager says there is a monitor. Nvid uninstalled drivers, restarted with vista and a map nvid in loads of drivers, restarted - same problem. Bought the new 8400 graphics card and equipped - same prob. Reinstalled vista - same prob.
There is no other program on this to clutter anything in System. At the most recent drivers, even mounted new graphics card.
Help please.

G ' Day Manasa P, problem solved! Unfortunately no you (not disrspect to you somehow). As I said no monitor icon in the Device Manager. Change the drivers of graphics for the standard vga drivers to fix the problem. reboot to normal. Device Manager should now list monitor. Load the drivers depending on monitor. Restart and load the drivers for the graphics card via Device Manager. reset. I hope that fixed the problem.
Thanks for your help, realize looking at the list of problems you have hard time, trying to unravel the problems of other people. That good luck.
Hope you can pass on my stationary and can save you time.
Concerning
Robert Park

  • All the addon icons are missing in the window customize

    I use FF 3.6.18 on XP, Vista and Win7. Given that FF itself upgrade 3.6.18, Miss all kinds of icons of the addon. Needless to say most of the addons cannot work unless that icon there to click. When I went to the [toolbar Customize] window to drag the icons réécrirait tool/menu/status bars, I find that ALL my icons missing addon. The FF default icons are there, but all the addon icons are missing. I've seen a lot of messages from people with the same problem as FF4 running, but it is not only a problem with version 4. Most of the answers provided were advised going to the window to customize and dragging that icons back out - obviously written by people who have not been read the question very carefully. Others recommend clicking the [restore default icons] button. They did not read the question with much attention either. I have this problem on my PC, those running XP, Vista and 7. Yes, I already ran ladies of virus and spyware, and that has not helped one of my PCs. reinstall the addons is no help either. Since the problem is on all of my PCs in various operating systems and upgraded to FF4 seems to make things worse, it looks like a bug in FF. Most of my friends who use Firefox have the same problem. It is a bug, or is it repairable? Does anyone know how to solve this?

    After, with great difficulty, eliminating the motor leads from my system, I tried half a dozen other things, but ultimately never gave up is fixed without wiping my hard drive clean. However, the latest update of Firefox (3.6.24) solved the problem! on all my computers! Don't know what you people at Mozilla has done, but thank you, thank you, thank you. No idea what caused the problem, or what fixed it, but it's a happy camper now.

  • The Photoshop icon is missing after CS5 download

    Hello

    I just downloaded the Creative Suite 5 on my new computer laptop (OS is Windows 7) and for some reason the Photoshop icon is missing from my computer. It always works as it should, but it's an annoying cosmetic problem. Any help would be greatly appreciated.

    I must also warn you that I'm not very tech savvy!

    OK, in this case I think the icon file might have been moved or damaged.

    Lets try the step below:

    > Right click on the exe file-> PS CS5-> properties-> Shortcut tab change icon

    > Select the PS icon in the list-> OK

    > If you do not see PS icon is this list, click Browse, and then navigate to file Photoshop.exe [(C:\Program Files\Adobe\Adobe Photoshop CS5 (64 bits)... for 64-bit) and (C:\Program Files (x 86) \Adobe\Adobe Photoshop CS5)... for 32-bit]-> OK

  • Yellow triangle with! the wireless network connection in the task bar icon, but ok in Device Manager

    I still need help: 11-24-10' uncorrected problem after all

    I have a laptop of refurbished HP older Pavilion ze5385US who has recently lost the wireless connection.  Now, I have to leave it plugged in to use, not practical at all.  I did the right click on the icon to open the network connections, left clicked wireless network connections and then clicked "repair this connection.  The uninstaslled of the computer, and then was not able to reinstall.  When I checked D, it was empty.  I thought it was where restoration stuff should have been.  So I downloaded and reinstalled much Express IEEE 802.11 PCI card Lan, until I found the one that the computer would be except.  Now, it appears in device very good Manager, but has theyellow cone with! on the icon in the status bar at the bottom.  When I raised it lights, it is said: 13 of (ANY) wireless network connection, speed: 11.0 Mbps, Signal strength: Excellent, status: limited or no connectivity.  When I choose "View available wireless networks", I get "Windows cannot configure this wireless connection.  Under network without wire/support/details of connections, Iget physical address: 00-02-8A-92-BE-0C, IP address: 169.254.196.112 subnet mask: 255.255.0.0, then the default gateway, DNS server, WINS server & have not enumerated values.

    Hello

    I thank you and wish you the same.

    I see that your problem has been solved using the HP driver that you mentioned on Thursday, November 18 in your message and the Express.sys is a problem with Windows install.

    I suggest to install the version of Windows install 4.5 on the system from the link below and then update the driver from the link that was attached to your question before and check.

     

    Step 1:

    Install windows install 4.5

    Windows install 4.5 Redistributable

    http://www.Microsoft.com/downloads/en/details.aspx?FamilyId=5A58B56F-60B6-4412-95B9-54D056D6F9F4&displaylang=en

    Step 2:

    Update the driver from the link you mentioned in your previous post.

    I suggest you to check with TP-link if this model is compatible with Windows XP or not.

  • Envy of HP Touch Smart 17: HP Mobile Data Protection sensor missing in Device Manager

    I had a HP 3D drive guard error after installing drivers of devices in Device Manager in the control panel.  I looked on Google for answers and they said to find the right driver on the HP website, sp71811, uninstall the old drivers and install a new one for this laptop.  I did this and got an error DLL missing after restarting the machine.  You told me to uninstall again and reinstall and do not forget to restart after uninstalling.  The installation said it was incomplete, that the files were not completely installed.  I got an error message about a missing .dll file (don't have the error code now).  Something about a file stack error.  I went to the Device Manager and uninstalled the driver for the HP mobile data protection thinking can I reinsall that Device Manager but he removed the accelerometer.  Now I can't download HP 3D DG due to missing accelerometer.  How can I retrieve the accelerometer and the original problem with HP DG 3D?

  • Re: Drivers for BT missing in Device Manager

    Hello!

    I have a Qosmio G30 with Win XP MCE... A few weeks ago, I have reinstalled my system normally with recovery cd... Now, I noticed that when I want to use bluetooth, I find no sign of bluetooth technology and even without driver bluetooth in my device manager... I also tried to install battery bluetooth and bluetooth monitor but these utilities were functionless... I read a lot of discussion in this forum but you have not found a similar problem...

    as far as I know BT device is listed in Device Manager, of only if BT is enabled. To do this turn on WLAN using the WLAN switch (the WLAN led should be on). Combination of keys after you have made this BT activate using FN + F8.

    Can you please tell us what will happen when you do this?

  • CD-ROM/DVD-ROM missing from Device Manager, FRUSTRATED!

    I jumped on my computer today, to copy a disc in iTunes and found that Windows is for some reason, do not recognize my DVD/CD drive.  Now, the drive is very good; This works.  I put in a disc and it runs.  But that's all.  I go to Device Manager to see what is the problem and I find that the knot of READERS of CD-ROM/DVD-ROM is missing altogether.  -What happened?  If anyone can help (not you, Rob;) I already tried everything in your list of suggestions), please.  I would appreciate.

    DT

    Hi Dtorres,

    • What exactly do you mean by it works when I insert the disk?

    If the device is missing in the Device Manager, it may be due to hardware failure or if the drive cables are not connected properly. This can also happen if there is a damage in the drive cable, windows will not be able to detect the drive.

    However, you can contact the computer manufacturer to verify if there is any firmware that you can install for the CD / DVD player and if you can run a diagnostic tool for the material.

    You can also start the BIOS of your laptop and check if the drive is detected in the BIOS and post back the result.

    I hope this helps. Let us know the result.

    Thank you and best regards,

  • Satellite L500 - wireless network adapter is missing in Device Manager

    Hi guys, I have read a lot of discussion but not found a job of answer to my problem and yet, although this doesn't seem to be a common problem, so I was wondering if someone can help out me. Model laptop is L500-1VT. There is no switch on / off external WiFi.

    In short:
    -Awake portable sleep, already before his pan was connected to wifi, but suddenly had no connection.
    -Adapter doesn't not appear in Control Panel, so checked Device Manager. Isn't there. : S

    -Thought that maybe something has come loose? But then checked msinfo32.exe and adapter was seen here.
    -Read a lot of discussion about it being from PVAT with FCU, then followed advice doing reinstalls and uninstalling and reinstalling driver wlan (this being seen in lost msinfo32.exe.) Unfortunately, it did not work. Still not apparently visible to windows.
    -Fn + F keys never worked and after reinstall of the above programs still do not work.
    -Wireless is enabled in the bios.

    -However, and I don't know if it's the crux of the problem. * Wireless is DISABLED in HWsetup.exe. When I try to turn it on, it says reboot needed. If I do that immediately, or much later, I get a blue screen and memory dump.* so I'm sure it's a software problem.

    -J' also tried restores system and disks of microsoft repair. But I am at a loss about what to do now, so use my phone via USB WiFi to connect to MTAs.

    If anyone has any ideas, it would be great!

    Hello
