DirectX (Direct3D) Disables Itself
Jul 11, 2010
[code] Lately my DirectX 11 disables itself. I have to reboot to fix it. The last time it happened Aero was still working. I turned off Aero and turned it on again and it doesn't work. In dxdiag, DirectDraw, Direct3D, and Texture all are disabled. DDI Version also shows as Unknown. I restarted and all is fine. I have had Windows 7 for about a month now and this has only happened the past 1-2 weeks. My ATI drivers are from Asus and are 8.703.Is there any other information I should look for and post?

1. Bioshock wants me to install DirextX 9.0c. I was wondering if installing this will mess up DirectX11.
2. I'm using a DX10 video card so the Dx10 features on my DX10 games should work wil DX11 right?

I *WAS* having this problem trying to play RIFT Beta, however, a quick search of your forum gave me just the answer that solved my problem. The launcher would start, then I would click play, and a directx update window would open, when I clicked the next button on the installer for directx (the window did not provide a version), I would get the error box telling me to look in my directx.log file, which contained many lines of error code about missing cab files. I then used the link provided in a closed thread on this forum that took me to the Microsoft Directx software page, I downloaded the latest rev of the runtime sdk kit, after 6 minutes of installation, RIFT launched perfectly. I have Win7 home premium 64bit running on a standard shelf version of an hp box with intel i3 core and intel onboard video... Here is the link I used: [URL]

I have a bit of a weird problem; here's the whole story. For the sake of an easier explanation, let us call the PC's I have mentioned PC-A, PC-B and PC-C. So, I first had PC-A and PC-B installed (this was years ago), and the problem first started appearing right away; whenever I tried to transfer a file between the two PC's, that's size exceeded roughly 1 MB, PC-B shut down all connections (which means it lost LAN connectivity, and could therefore not connect to the internet (as the broadband is connected via LAN to the switch)). At first, I didn't think much of this, as the problem is easily avoidable by transferring files using a USB stick instead (Note that smaller files can still be sent without any problem, and the PC's even perform well in Games, when playing LAN). However, I decided to get a third PC (PC-C) up and running recently, and have correctly (as far as I can tell) installed the PC upstairs on a different switch, connected to the LAN and internet as well. However, now the problem has became a bit of a greater nuisance, as whenever I try to send files from PC-A to PC-C, PC-B locks itself down again (my guess is that this happens because the traffic is still being applied to the PC-A-to-PC-B switch, which then leads me to conclude that the problem is in the switch).
I have so far tried changing switches, changing the jack that PC-B is connected to in the switch, changing various options in the Network Adapter settings of PC-B and disconnecting and reconnecting PC-B to the network(both physically, by plugging the cable out and back in, and via the software, by enabling the LAN connection that PC-B is usually connected to as it disables itself after a while (it gets stuck on Enabling... when I try and do this)), and so far the only way to get PC-B's networking working again, is by rebooting the PC itself.Please also note, that I am able to ping between all PC's before the file transfer, that the other two PC's do NOT need to reboot in order for their network to still function properly, that only files of a filesize of over ~1 MB cause this malfunction, that sometimes (I have yet to see a pattern of this occurring) PC-B CAN ping the other PC's but has a 50% packet loss average, and takes about 3k ms to get a single response, while the regular ping speed is <1 ms, and that transferring files over wireless networks (from PC-A to a laptop connected to the switch or broadband) does not seem to trigger this problem

Just installed 7100 and was setting up. I have a Toshiba HDTV on DVI (display numbered 1) and an Acer lcd on VGA (labeled 2). The acer is set as the primary display and all appears fine but when I'm not using the hdtv I'd like to turn it off and just use the lcd. When I turn off the hdtv I hear the sound for disconnecting hardware and the signal is cut off from the lcd putting it to sleep.
I tried the latest nvidia drivers (oh yeah, 8600GT) and it made the system super crashy with bsod's and everything. Can I disable plug and play, which I suspect is the problem, on just that monitor?

SPDIF used to work flawlessly with WMC7 and Intel G620 integrated graphics. I only needed to set the SPDIF as default in the Via HD panel.Since installing an HD 6450 video card I have to re-select this option everyday, or more if the HTPC stays in sleep mode for a long time. In fact the HTPC is always on & just goes to sleep when not used.The other day I found an SPDIF setting in Control Panel > Sound and made it the default, but that made no difference.

I'm running Windows 7 on a Compaq Presario CQ56.I've been having trouble with the multiple display settings changing on their own on my laptop. I've never had an external monitor hooked into my laptop, but for the past week or so my laptop will give me a notification that an external monitor has been plugged in, then it will disable though nothing has been change. I havan't downloaded anything recently besides windows updates.

I use a screen magnifier/reader,it doesn't allw aero to function because it uses the graphics card,a known mirrored driver issue,not fixable at this time.So I would like to either disable aero altogether so I can use a black theme,or use the built in windows7 basic theme but with black instead of the default colour.
I know I can shut off aero peak and aero shake but how do I shut all of aero off,other than using the Windows 7 basic theme,and that is why I asked about changing the colour in the basic theme.I hope that makes sense.

I have been running happily with an All in One Medion desk top, which I have modified slightly. It is really a notebook chip based system, only two sata outputs, but it does have a touchscreen and digital tuner. It is a 2.3Ghz Pentium dual core. 4 GB mem and 1.5 TB over two drives.
I pulled the DVD drive out of sata 2 port and fitted it in an external housing on a USB port. Then I wired the sata 2 port out via an eSata socket to a sata HDD docking station.
I have been running six months with two versions of Win 7 Home premium 64bit in dual boot mode with no probs. Last week I decided to replace the 64 bit with a 32 bit version so as to run some older programs.
So I formatted the external 1TB drive and loaded win 7 32x from the original disks. Took while with all the updates and SP1.
While doing this, I had no problem with the DVD drive but, as soon as I was up and running, the DVD drive stopped reading disks. Swap boot back into Windows 7 64 bit and it is fine, boot from Windows 7 32 bit and it is a dodo. It recognises the drive ID but will not open a file or boot from a bootable disk. I have checked for out of date or missing drivers but nothing shows.
I suspect I have a protocol problem, Not sure. It appears to be using a new Windows 7 sp1 driver. Or maybe something wrong in Global settings.

So I've had sudden trouble with my webcam in the last two days, which is kind of irritating because I rely on it a lot. Specifically, when I try to activate my webcam, Windows disables the USB controller its connected to, reporting "Windows has stopped this device because it has reported problems. (Code 43.)" I've tried the webcam on another computer and had no problems. Disabling/reenabling doesn't do anything, neither does using a different USB port. I've tried the other solutions I've found online, including running the Hardware troubshooter, taking the battery out of my laptop, and unplugging the power for a couple of hours. I've removed the USB controllers, and restarted my computer.

I have a desktop PC running W7x64 for which I rely on my Alfa AWUS036H wireless USB adapter for an internet connection.
Windows 7 has a feature that seems to detect whether I turn off my monitor or not (for one reason, I know this because it makes a noise when I turn it on or off). When I turn my monitor off, my internet is disabled for some reason. I would like it to stay enabled so that I can download files and keep other active connections while the monitor is switched off.
I can verify that the indicator light on the USB adapter turns off when the monitor turns off and that the wireless utility that controls the device senses no device is present (i can see this using my secondary monitor, behavior only occurs when primary monitor is turned off).
Does anyone know how to disable this from happening? I have tried both turning off "Selective USB Suspend" and unchecking the "Allow computer to turn this device off" in the properties of the wireless adapter in device manager.

I'm having a bit of a conundrum. My Toshiba touchpad has developed a bad habit of disabling itself at random.The device is listed as a Synaptics Touchpad V7.2.I'll be typing along, or moving the mouse, or just doing nothing at all (waiting for a download to finish, for instance) and the mouse will become suddenly disabled. The only way to get it back is by pressing FN+F9 or sometimes to press the enable/disable button immediately above the mouse. I know I'm not pressing either of these by accident when the mouse turns off.When this happened, I took it as a sign that it was time to reformat the hard drive and start fresh. Even during the Windows installation, the mouse continually disabled itself. After installing the Toshiba Value Added Package and the Synaptics driver, the only change is that now I can see a big icon in the center of the screen alert me when the state of the mouse switches from enabled to disabled.
I'm noticing now too that it's not just disabling itself. If I don't re-enable the mouse right away, it will renable itself after a few moments. This can happen as much as once every few seconds and makes getting any real work done impossible.

I just installed windows 7 (build 7000) on my older dell inspiron 700m. Everything has been running smoothly except for what i believe is a video driver problem. My screen max res. is 1280x800 but it's limiting me to 1024x768 right now. I also can't do things like screen-savers, because when I try to enable them, instead of the preview, i get a message saying that it isn't compatible with Direct3D. I went to the dell website and looked around for the newest driver.
On my system info page, it says that I'm using a standard VGA graphics display.
I didn't have this problem on XP SP3
Any help would be great.

I just got a new laptop (Lenovo G770) and am busy configuring Windows on it. I am running into an annoying issue with my input devices. Whenever I type or do anything with my keyboard, it disables my touchpad for about half a second. Since I am an avid user of keyboard shortcuts, this is highly annoying and is messing with my productivity. I can't figure out how to turn it off--when I search for answers I just see lots of threads from people having the opposite problem, who want to disable their touch pad while typing. I currently have the Synaptic driver installed controlling my touch pad, and I can't see any options in its settings to disable this "feature".

Starting last night my Dlink DWA-130 is causing all of my rear usb ports to not work. If I plug it into the front the computer doesn't even recognize it. I have tried using different ports on the back with the same result. I have even reinstalled Windows and the problem is still there.
Not Sure if this helps but...

mobo: AsRock 970 Extreme 3
processor: Fx 4100
gpu: Radeon hd 6570

I have a my HTPC plugged into a 5-port switch along with my Xbox 360, PS3, and U-Verse TV box. Naturally, all 5 ports are being used with line 1 going into my router. There are 3 other computers in my house plugged directly into my router.My problem is that my network ceases to work whenever I plug in the switch. I am neither able to access the internet or view any other computer on my network for file/printer sharing. Running ipconfig shows that I have no LAN/internet connection. If I unplug the switch and plug in the components individually, then everything works normally.I have tried 3 different switches but I am getting the same result. It is very inconvenient to have to manually unplug and plug in my various game consoles and TV box in order to enable them to access the internet.

When running Kubuntu in Sun VirtualBox it disables Windows audio devices. Only way to re-enable audio seems to be reboot. When running Ubuntu, it's OK. No problems with Windows devices. Both Kubuntu and Ubuntu v. 9.04.
I like KDE more than Gnome, that's the reason for Kubuntu.
Any ideas?

I will preface all this with I am not particularly knowledgeable regarding computer stuff, but am willing to learn!OK I've been having a problem, similar to some other posts, where Windows Explorer (not internet explorer) seems to spontaneously stop responding. When it does, I can restart windows explorer and it always says "windows is checking for a solution" but never finds anything. Whenever this happens, which can be as often as every 5 minutes, it inexplicably disables my wireless adapter (belkin wireless g usb) which occasionally decides to not respond and not turn back on
