  • Windows 7 sees my second monitor as "generic non - PnP" and will not let me set the correct resolution

    Hello

    I just installed Windows 7 Professional 64 bit on a new hard drive on my Dell Studio 540. The PC has a graphics card ATI Radeon HD 3450 and has a Samsung 226bw 22 "monitor on the digital output. This works very well, and has the resolution of 1650 x 4050. When I am running Vista (on the previous hard drive), I got a monitor flat 14 "old on the other out, and it worked fine (although at a lower resolution).

    I added a monitor AOC F22s + on the other output, expecting to be able to put this to the recommended 1920 x 1080 resolution. Unfortunately, Windows has developed the driver for this monitor "Generic non - PnP" and will not let me set the correct resolution. To the maximum it will allow is 1600 x 1200, (as well as all other resolutions it allows) do not use the monitor at maximum capacity, which is the ratio of evil anyway, so the display seems tense.

    I run Windows Update, so have the latest drivers. I tried to install the other drivers, but nothing helped.

    I tried to unplug the Samsung monitor and restart the PC, so that the AOC, one was the only monitor it and he always had as 'Generic non - PnP' with the wrong resolution.

    Someone at - it ideas? I'm at my wits end. AOC support did not understand and could only suggest that the monitor was faulty, but the place where I bought it insist that it works very well and so no Exchange or get a refund (no restocking fee, which is a RIP-OFF).

    I really want to use both screens and would appreciate greatly any help that anyone can give. I hope I gave enough information. If I didn't, please let me know.

    Thanks in advance,

    Alan

    PROBLEM SOLVED!

    It turned out that my VGA cable was wrong and that it was not send the right signal to the computer. The screen worked fine with a VGA monitor, but the PC has not said that the new monitor is a PnP I tried a different cable and it worked fine.

    Thanks again to all who have suggested things.

  • Satellite L850 - Win8.1 will not let me install the chipset drivers

    Hello

    After I've upgraded to pro 8.1 windows 64 bit 64-bit windows 8 (preinstalled), I thought that windows will not let me install the chipset drivers (downloaded from "toshiba site" for windows 8.1 pro 64-bit), but they stay with windows drivers installed for them.
    The Device Manager displays all installed and properly using. In addition, during the implementation was executed to install the chipset driver, he skipped most of them, to install a missing driver only (unfortunately have not kept any screen to show). I tried to install using the Device Manager (automatic search or manually navigating the computer files downloaded from the site), but it keeps saying that the drivers are up-to-date (drivers with the version from 2006, when later seen on the site are 2014). Any suggestion what to do?

    Version of the operating system: Microsoft Windows 8.1 Pro 6.3.9600

    Just bought 'settlers of Catan.  Tried to play and went to App World, and it is uninstalled.  So I go into options and the 'install' option is not there!

    Help!

    Hello and welcome to the community!

    I suggest that you clear the cache of the AppWorld application:

    2. go to my world

    3. follow one (and only one!) of these steps:

    3. for the BB keyboard-oriented - hold down the ALT key and press on, in the sequence R, then S, then T

    3B. for touch screen only BBs - hold the num-lock (! 123 button) so that it hangs and then press on, in the sequence 3, then 4, then)

    3 c for the most recent (e, g., OS6 and 7) BB s, see this KB:

    • KB24714 How to clear the cache of BlackBerry App World

    4 AppWorld must close

    5. If your BB locks after issuing clear cache, do a battery pull reboot

    6. return to AppWorld/MyWorld (it can be slow, while it re - sync).

    If (4) stage arrives not as described, then the empty the cache failed.

    I hope it'll work for you! Good luck and let us know!

    If using your firewall software, then it depends on where the settings to disable the firewall.

    Once the game has installed switch back on the firewall, this should allow the firewall to accept the sims 3, if not you will need to go into the settings of exceptions and add sims 3 for her.

  • Satellite P100 - 194 PSPA6E does not start and will not let me install Windows

    Hello

    I have a problem with my Satellite phone, witch, I got from my brother. I don't know what he did with it, but he does not know.

    When I start the PXE - E61 "Media test failure, check cable" appears. In the BIOS I put in the directory Boot LAN mode on the last position, but despite this failure E61 appears.

    I tried to reinstall Windows XP. The laptop started from the CD and the blue screen appeared and loaded XP drivers needed. But at the end of it, when you enter normally on the menu to choose where to install windows, the screen is black and in the upper left corner a small beam blinked on and outside and nothing happens plus.
    The same thing happens when I leave the laptop HARD drive and start again from the XP installation CD but this time without the HARD disc logically.
    So I thought that the HARD drive is broken and I put it in my desktop PC to test. I installed XP on the drive HARD Satellite in my PC, which worked without problems in my PC. So, I come to the conclusion that the HARD drive is not broken.
    And my BIOS Satellite detects my HARD drive and displays the name of it.

    But what is the problem with the laptop when it is not the HARD drive and BIOS show the good name of the HARD drive? Can someone help me please?

    Hello

    The story is very strange boyfriend generally that the PXE error if the laptop tries to boot from LAN. But in the case where starting LAN source in unavailable, the PXE error appears and shows this message.

    Usually, the BIOS passes LAN Boot option because the other options are not active. This means that the CD/DVD drive does not any bootable disk and the HARD disk is dead.

    So, as you can see you hypothesis was right that the HARD drive could be faulty

    In any case, try to access the BIOS and set it to the default settings save changes and then try to reinstall Windows XP.
    You might also try another HARD drive, I know as your fist HDD recognized correctly but it s worth a try to test the 2nd HARD drive.
