Old Vga Monitor No Longer Works With Windows 7?

Dec 8, 2011

I have just recently built a new computer and am trying to use my older vga monitor with it. The monitor displayed fine while installing the os but after it finished the monitor goes right into sleep mode. I updated all my drivers for the onboard video and my video card and have switched between the two in my bios trying to make it work. So far the monitor displays up to the loading windows screen then goes straight into sleep mode. The most annoying thing is that the monitor works fine as a secondary monitor, just not a primary.

DVI Port No Longer Works - Windows Won't Detect Monitor

Apr 23, 2012

I have a Sceptre X20WG Naga 20.1" monitor on a DVI connection with my EVGA GTX460 card. I was using it yesterday while studying for finals and decided to hook up my 37" Westinghouse TV via VGA connection, using a VGA-to-DVI converter to plug into the graphics card, as the card only has dual-DVI and mini-HDMI outputs. It was working grand as a second screen, no issue at all. Now, today, I turned on my computer and my Sceptre Monitor wasn't outputting any images at all, it just said no signal detected and then went to sleep, though my computer was still on.

So I turned on the TV out of curiosity and found that the TV was now the main screen, still with the VGA connection, and I hadn't unplugged anything since yesterday. So I logged in and right-clicked on the desktop, went to screen resolution, and here it says that the TV is the only screen detected, even after hitting detect. So I unplugged the VGA from to TV and plugged it into the Sceptre Monitor. Turned on the computer and the monitor worked like a charm on the VGA cable. I also plugged the DVI cable that I was using for the monitor into the TV and that worked like a champ too.

The only reason this is bugging me is because I won't always be using the TV as a main display because it's kinda of a pain to sit close to a screen that big. So I am currently on this forum while my monitor is using the VGA connection. It also seems to vary from which DVI port I use on the videocard because if I plug the VGA cable with converter into the 2nd port, there is no video output, but if it's in the first port, works great. I'm going to try just the DVI cable to the TV on each card port to see what the deal is there.

So basically:
The cable isn't the problem.
The VGA needs to be in the 1st DVI port on the card to work.
The DVI doesn't work at all when hooked up to the monitor.
What I want is to be able to use DVI on the monitor and VGA on the TV.

Specs:
Intel Core 2 Quad Kentsfield Q6600 2.4GHz @3.0GHz
8Gb Kingston ValuRam DDR3-1333
Asus P5G41T-M LX Mobo
EVGA GTX460(2x Dual link DVI and 1x mini HDMI)
Windows 7 Professional x64

Auto Detection Of Plugged / Unplugged Monitor No Longer Works

Jul 2, 2012

When I plug in or unplug my external display to my laptop, my display options no longer automatically reconfigure as they used to do. Now if I unplug the monitor, Windows acts as if it's still there, and windows that were on the monitor stay offscreen (as does the cursor, if that's where it was). I can manually move the cursor back, right-click load graphics properties and make changes OR do an F-key combo to move everything back on the laptop screen OR program a hotkey but these are all pretty annoying for one reason or another. Unfortunately this must have started happening sometime in the last two weeks--at the same time as I made a load of major computer changes.

However this did NOT include a graphics driver change (my graphics driver is current). At this point I feel it could be anything, but I'm wondering if it could be a recent BIOS update I did that HP recommended. By way of troubleshooting I did run Windows in safe mode with ONLY the "ATI Catalyst" and "AMD External Events utility" running on top of the basic services, in case a newly installed service was stealing hotplugging messages, but that didn't do anything. I've also gone exhaustively through my graphics driver settings to make sure everything there looks correct.

Windows Fax And Scan No Longer Works

May 3, 2011

We used to use ZetaFax, I'm told. I'm new to the company. We no longer use ZetaFax. Since bringing in Windows Vista Business and Windows 7 Pro computers, and Windows 2008 Server, we now use Windows Fax and Scan.We use Fax Server on the server with quad port RocketModems installed.Now, here's the problem.Some of our employees are having problems using Windows Fax and Scan. The way they use faxing is by finding the file (usually an Adobe Acrobat pdf), open it and then go to the Fax printer.This then auto faxes the document using Windows Fax and Scan.For most of our employees, this works fine.But, suddenly for some it does not work. When I visit the ones who can't fax, I open Windows Fax and Scan and try to launch it. It does not launch. On some of the computers, the user gets a message that the format must be tif. For others, they get a message saying that they can not access to the document folder.I'd like to remove Windows Fax and Scan on these computers and try to reinstall it and see what happens. How can I do that?

Find Command No Longer Works On Windows 7

Sep 21, 2012

We have a script that installs an application on a user's box. It can run on XP, Vista, Win 7.... So it uses the ver command and find to figure out what the os is. It used to run on my win 7 box. It no longer does. The find command now gets an error. I tried substituting findstr and it returns a good completion code regardless! The grep command works great but most machines don't have grep so that is not an option to use. I would just like to figure out why find doesn't work. The date for find.exe in the System32 folder says 7/13/2009. Is there something I can do to restore find? Listed below is the the command & output that helps determine the OS version using find/findstr/grep

Flash No Longer Works In Any Browser

Dec 28, 2009

I just got this new computer, running 64-bit Windows 7 Home Premium. Everything was working fine at first, but then it automatically updated some things. Now, Flash doesn't work online anymore, in any browser. The content starts to load, then the browser freezes, and I have to force quit it.

I have the most recent version of Flash Player, and I can still play .swf files I make myself, so I don't know what to do anymore.

I'm fairly sure that this isn't an isolated problem, as a friend of mine is experiencing the same thing.

In a possibly related problem, .avi and other video files on my hard drive no longer play, nor do music files.

I doubt my specs are needed, since this is almost certainly a software problem, but I'm running on a Dell Studio, with a 2GHz dual core processor and with 4Gb of RAM.

Desktop Background No Longer Works

Dec 16, 2012

So I opened up my tower to do some dusting and I accidentally dropped the tower door and the wires that power the tower door fan was ripped off. There was a red and black wire that has these weird looking prongs on them. I first did not know where they went... So I just looked at the 4 pin whole plugs and started to stick these two in these plugs to test... First few times I did this; the pc restarted and there was a spark....(could this be y my background no longer works?) Then I found two holes out of the four pinned plugs that powered my fan.. Hurray I thought cause the fan was powered, the blue light was on and I was happy for that moment. Then I realized my background was just a blank color.. So I right clicked/personalize/desktop background/ set up the photos I saved/hit save changes. and nothing. no background.

User Switching No Longer Works After SP1 Install

Mar 21, 2011

Windows 7 Ultimate, 32 bit. Not on a domain. After I installed SP1, "Switch User" disappeared as an option. "Hide entry points for Fast User Switching" in GP Editor is set to Not Configured.

I also checked the Application Information service as Andre suggested, and it was not running. I started it, set it to automatic startup, and rebooted. Still no joy.

I have uninstalled SP1, and I now have the option to switch users as I did before installing SP1.

I'd prefer to keep my system updated, but for this system anyway, the ability to switch users as opposed to logging off is more important.

New Hard Drive, Video No Longer Works

Sep 24, 2012

I installed a hard drive and upon installing drivers for my nvidia gtx 460, it just gave me a black screen once I got to the login screen. Went back in to safe mode and got older drivers, that didn't work either. I have tried 4 versions of the older drivers and it all goes exactly the same. Clean install of windows 7 Home Premium 64. Or do I just need to get a new motherboard/videocard? Also I have a dual monitor setup and the second monitor doesn't get a signal.

Nov 11, 2011

Nvidia Driver No Longer Works - Graphics Card Broke?

Dec 18, 2012

a few days ago on boot up my laptop restarted and then attempted windows repair. came back to life. tonight while viewing Internet my screen went black. i had to hold the power button down to restart. i chose start windows normally. when attempting to load windows i got a blue screen saying "attemp to restart display driver has timed out". after a few attempts i have managed to get it into safe mode and deleted the nvidia graphics driver. restarted and all was fine (low resolution). i installed the graphix driver again an it happened again. is my graphics card broke?

alienware m7700 d900k
amd athlon 64 x2 4600+
geforce 6800 ultra
windows 7 64
2gig ram

the nvidia driver does not detect my graphix card so i have to add it in the setup information file. but i have had no problems for about nine month since i bought this laptop second hand.

i joined this site for another problem a few days ago. slow speeds and constant hdd access but had a good clean out and was going to see how it went. then this happened. i do not think they are related.

8500GT Works When Monitor Turned OFF

Nov 29, 2009

CRT 21/750 Formac (SonyGDM) / point of view 8500GT / Windows 7-64

xfx 680i LT / 4 gB ram / Q6600 / latest XFX BIOS

(My first PCIExpress card - be gentle ;-) Here's what I've been doing

for what seems like the best part of two days -

1 Boot in safe mode, disable 8500. Reboot.
2 Drivesweeper'd nVidia display drivers in safe mode. Reboot.
3 Restart in safe mode to verify drivers gone, but 7 just goes ahead

and renistalls 195.62 anyway (A moderator on the nVidia boards says

that these latest drivers should NOT be installed in safe mode.) & asks

for a reboot.

4 Reboot as instructed, then screen blanks after entering password;

pretty much what I've gotten from day 1.

> Now, just today I tried something I saw somewhere here (?) where

A I reboot the PC (after 1,2,3 above) with my monitor OFF
B Enter my password 'blind'
C I finally get to a proper desktop which appears to be using the

correct drivers (Refresh rate looks much better) but I can't verify

graphics card changes, as this causes a blank screen again.

Monitor is the only device plugged into the GF card.

Where have I screwed up?

Laptop No Longer Allows 1680*1050 On External Monitor

Sep 27, 2009

I have an eeepc 1000he with a viewsonic 22inch screen VX2255wmb. I have been using both for a while now with the dual screen setup without any problem. Since a couple days now, my external monitor won't show the optimal resolution which is 1600*1050. In the screen resolution set up page in windows 7,

it used to highlight the optimal ones that respected the aspect ratio of the screen but now it just shows all of them and when I set it up at 1600*1050, I get an error message on the external monitor saying that the configuration I chose is out of range. Now the highest resolution I can use is 1400*1050.

I dual boot with windows xp and I don't have this problem with it. I didnt use any driver for both Os, just plugged the monitor in and it worked.

Anyone has an idea?

Windows 7 Not Recognizing Second Monitor For Dual Monitor?

Dual Monitor Setup - Fullscreen Goes On Wrong Monitor

Aug 14, 2012

I am running a dual monitor setup with my TV hooked up via HDMI to my laptop.

Everything was working fine before, I always had the laptop as my main display yet I could play a video or a game fullscreen on the TV.

Since a couple of days, as soon as I put something in fullscreen, it immediately goes on my laptop, regardless if it's open on my TV or my laptop. I don't remember changing/installing anything that could've changed that...

I checked a bit in the AMD vision software and the Windows control pannel but I can't seem to solve my problem without switching my TV as the main display. I also made a quick search on google as well as here but the problems were mainly with Flash, which isn't in cause here.

Here are my system specs:

Toshiba Satellite L75D
Windows 7 home premium 64-bit
AMD Radeon 6520G

Dual Monitor Issue, Secondary Monitor Is Undetectable

Jan 6, 2010

I have just did a clean install of Windows 7 ultimate from XP and I am unable to get my dual monitors to work like they did in XP.

I have a DVI Radeon graphics card plugged into the agp slot, and a Nvidia geforce vga adapter plugged into a pci slot of my dell optiplex 755. When I am in the screen resolution settings the second monitor cannot be detected.

In bios I have 2 options under primary video adapter and they are auto, and onboard card. When set to auto the Nvidia card gets a signal but the Radeon does not. There are no conflicts in the device manager, and all of the drivers are up to date.

When I change the bios option to onboard card the Radeon adapter gets a signal but the other monitor cannot be detected and in device manager there is a yellow exclamation mark next to Standard VGA adapter and a code 10 error that states the device could not be started.

I have powered down, and unplugged every cable, I also tried to use the integrated VGA adapter to the Intel G31/G33/Q33/Q35 Graphics Controller but the computer will not even boot. I get

"System Halted

Attention Unsupported Video Configuration Detected"

I have two monitors, both work fine as standalone but Windows will not detect either as a secondary.

Please help me someone, I am so used to having my helpdesk email open in one monitor and all of my other work in the other monitor.

Primary Monitor Switches To Secondary Monitor?

Oct 21, 2010

I recently had an older HP Pavilion Media Center m7760n Desktop PC rebuilt. The old power supply fried the motherboard so I need to get a new power supply and motherboard. Here are my current specs.

Mainboard : Asus P5QPL-VM EPU
Chipset : Intel G41
Processor : Intel Core 2 Duo E6420 @ 2133 MHz
Physical Memory : 2048 MB (2 x 1024 DDR2-SDRAM )
Video Card : Intel(R) G41 Express Chipset (Microsoft Corporation - WDDM 1.1)
Hard Disk : WDC (1000 GB)

[code]....

As you can see from above, the "video card" is actually integrated into the motherboard.The computer works perfectly except for one major problem. I have 2 monitors, one is 22" with 1680 x 1050 resolution and the other is a 15" monitor with 1024 x 768 resolution. At the back of my computer I have a VGA port and a DVI port. The 15" is connected to the VGA port and the 22" is connected to the DVI port.When first starting the computer, the 15" monitor was recognized as the primary monitor while the 22" was recognized as the secondary monitor. No problem. I simply went to the display settings and set the 22" to be the primary monitor and the 15" to be the secondary monitor. Unfortunately, this setting seems to reset as soon as I reboot the computer. The 15" is always set as the primary monitor on start up, forcing me to set the proper settings all over again. What's worse is that even after I have set the proper settings, they sometimes revert back when using Media Center or other programs. Worse yet, sometimes the monitors both go completely black ... as if the monitor settings were about to switch but got locked up some how.I'm assuming that perhaps the on board video has a primary port (VGA) and a secondary port (DVI) but even still, shouldn't Windows 7 be able to over-ride this and save these settings so that the monitor settings remain the same during startup and regular usage?

Windows 7 No Longer Genuine?

I built my first custom PC about 4 months ago. I bought windows 7 ultimate off Ebay, installed it, entered my product key, installed Microsoft Security Essentials and everything worked fine. At the time it said my copy of windows 7 was genuine.Now 4 months latter my computer randomly pops up with a message telling me my copy is no longer genuine. Microsoft Security Essentials is no longer running, my desktop background has turned black and in the bottom right hand corner of my screen there is a message saying

-"Windows 7
-Build 7600
-This Copy of Windows is not genuine"

As far as I can tell my copy of Windows 7 is genuine. It came with a sealed COA, a proof of License label and holographic discs.

Windows 7 - XP Can No Longer See/share

Nov 10, 2011

We have been using a Windows 7 machine and an XP machine for some time now - they are using the same workgroup name, and were sharing files using the Public folder on Windows 7, no problems. The XP could also connect to the printer, which is hardwired to the Windows 7.

They are both using wifi in our building. The wifi, which is owned by the landlord, used to be called Ourwifi. A couple weeks ago, the power went out in our building and then there was a problem with the wifi and the internet/cable company came out and changed it. It is now reconfigured as Ourwifi2. It is password protected.

Since that change, both the Windows 7 and XP computers are able to access the wifi and use the internet, but now they cannot share files. As far as I know, nothing on either of the computers settings had changed.

The Windows 7 computer was turned OFF when the power went out; the XP most likely was ON (because that user tends to leave it on all the time). Since I've been trying to reconnect them, I may have changed something by accident.

So here are the settings in the Windows 7:Network and Sharing - Under advanced sharing settings, password protection sharing is OFF under "home or work" as well as under "public." Workgroup is listed as the same one as the XP computer (ourwkgrp). In Windows 7, under active networks, Ourwifi2 is listed as a"work network" Windows 7 has Norton running; I'm unsure if it has had any auto-updates that may have changed accessiblity settings. I can't find in the Norton settings how to add all those TCP and UDP numbers suggested in a post elsewhere that might help it find the XP machine. On the XP machine -- XP can see (or thinks it sees) the Windows 7 computer over the wifi -- if I look at "view workgroup computers" in the XP -- Windows 7 shows up, but if I attempt to connect, I get a message saying it is an invalid path, cannot be viewed over the network.

XP cannot print to the printer connect to Windows 7. It can't see the printer b/c I can't expand the Windows 7 folders that show up under "view workgroup computers."

how to access anything if you send "change this to on," etc.
