Not Recognizing DirectX - Screen Flickers

Sep 30, 2007

I had to reinstall my OS (Windows XP) to correct a problem I was having. I did so, and afterwards reinstalled all my drivers and such to get everything back in working order. Everything is fine now, but for some reason Windows isn't recognizing DirectX. Whenever I try to run a game (for example, World of Warcraft), the screen flickers a few times (as if it's changing the resolution), then the game shuts down. In WoW's case, I get an error message stating "World of Warcraft was unable to start up 3D acceleration. Please make sure DirectX 9.0c is installed and your video drivers are up-to-date." (again, no game is working, but WoW is the only game that's actually giving me a specific error message).

My video card is an ATI Radeon X1650 and I uninstalled the drivers for that and reinstalled them, which did not correct the problem. I'm certain I DO have DirectX 9.0c, as I installed it just yesterday and running dxdiag confirms that I do indeed have that version of DirectX installed.

Directx 10 Supported By Xp / Install Directx 9?

Apr 29, 2008

Just formatted my desktop and installed a fresh copy of XP Pro on it. I did a search on google and found that some people said XP does not support directX 10, but then when you go to the directX website to download it, Windows XP IS under the list of "Supported Operating Systems". So is 10 supported by XP, or do I have to download 9.0c?

Full Screen DirectX Applications And Games Resize Background Windows

Mar 12, 2008

I consider myself somewhat experienced with computers in general and Windows in particular (been using computers since the DOS days), but there is a thing with windows that rather baffles me. The thing is that since some time ago, whenever I start a game or any other DirectX program in full screen it resizes all opened windows to that program�s screen resolution. Even dxdiag full screen tests seem to cause it.

Once the full screen program exits or if I alt-tab out of it, all mine previously maximized windows are resized to fit in whatever resolution the DirectX app was running but they seam to think they are still maximized (2 squares instead of one on the maximize button and I need to press it twice to actually maximize them again, and also their size when not maximized seam to be changed to the app's resolution as well I normally run my desktop at 1280x1024 resolution

Monitor Freezes And Flickers

Sep 14, 2005

I have a laptop computer. The bottom 1/4 of the screen is freezing and at time it flickers in that area. If I slightly twist the upper left corner of the monitor I can see through the frozen area but it starts flickering again. It never goes away. I haven't a clue as to what is causing this so I'm turning to those of you with experience in the matter.

Start Menu Items Disappear - Explorer Flickers

Dec 5, 2007

In last 24 hrs I am getting some very strange and vexing behavior from Windows Explorer and the start menu. Hope someone can help. The start menu programs pop up, but disappear before I can click them. Windows screen flickers at the same time when the start menu items vanish, and also flickers at other times. Fonts on the desktop, once just white, are now showing up white on a black rectangular background - didn't do any theme change. Windows Explorer has been crashing from time to time in the last week, no apparent reason. And the monitors are bleeding. Kidding about that last one, but am expecting it soon.

Start Menu Flickers/dissapears, Apps. Wont Launch & Minimised Apps. Wont Maximise

Jan 18, 2006

I am experiencing the following very strange intermittent problems and evil behavior in XP. My Start Menu sometimes only appears for a split second when clicked and will not stay displayed. Also minimised apps. wont maximise and apps. and short cuts on the desktop wont launch when double left clicked and instead show properties as if they were right clicked, Updated from SP1 to SP 2 as well as all the security updates. Ran Adaware and Spybot to find any unwelcome visitors. Adaware only found one minor issue. Ran Symantec Antivirus which found and quarantined several viruses. Ran WinDoctor which found and said it resolved quite a few issues. This is really a pain as it makes the system virtually unusable except for when it is behaving which is rare

Nv4_disp.dll And DirectX

Aug 23, 2004

I think I am losing what little sanity that I have left. I am having a couple of problems and they seem to be linked. Let's see if I can explain this so that it makes sense. I downloaded directx 9.oc last week don't know where it went because when I try to run "dxdiag" it says that I have vers 8.1 then everything crashes and all that I can do is push the reset button. Then when everything comes back I get an error message about the nv4_disp.dll

Apr 6, 2008

Hello all, I was wondering is there a way we can install directx 10 onto XP 32-bit. directx 10 is one of the main reason why Vista 64-bit is the best way to go for gamers, but I'm trying to save $150 and installing specfic drivers needed to run Vista properly on my PC. Looking at my specs, should I go head and invest in Vista Home Prem 64-bit or settle for XP 64-bit and hope for the best when SP3 comes out?

May 14, 2006

When I try to play Tony Hawk's Pro Skaker 4 on my laptop and I get the following error:The file SiS630v.dll is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer. The file sis7018.sys is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer.I think the main problem is that my drivers (audio and graphic) are not verified or whatever with Windows.How can I do this?How can I can each of their logo'd driver from SiS?

Mar 5, 2007

Tried installing a program but it needed DirectX8.1.. Went to MS site and found that DX8.1 is already installed in XP. DOwnloaded and reinstalled anyway. Program still doesn't find it. Think it may be a registry problem but am hesitant to fool around with it. Anyone know how to make XP default to DX8.1? (There are other DirectX's in registry, i.e DX3, DX6 etc. Think it may be defaulting to one of these.

Installing DirectX/3D: AGP Texture Acceleration Are Not Available?

Jun 26, 2010

HI currently have from what I can see a very common and well known problem with Direct3D. My computer has DirectX 9.0c ( 4.09.0000.0904 ) installed. I assume that Direct3D comes along with DirectX and should be installed seperately. However when I click on the Diplay tab Direct Draw Acceleration, Direct 3D acceleration, and AGP texture acceleration are not available and the option buttons are grayed out.

My graphics card is Ati Radeon 9250. I have downloaded the Ati Catalyst Control center and the drivers for the graphics card, however the problem still wasn't solved . Could someone please help me out with this matter, since it's really bugging me, any help would be much appriciated. I have also included print screens that I think may be good to look at and see certain information. If any other information is needed or you have questions that please do not hesistate as I really need to get this issue sorted.

Directx Error: Tells Me I Am Using Generic Drivers?

Jun 21, 2010

I recently got a virus on it and reinstalled xp. Now all the games I used to play on it are coming up with directx errors. When I looked at the errors in the diagnostic tool it tells me I am using generic drivers. So I popped my driver disk in and installed them all but it still gave me the same error. So I reinstalled directx 9.0 with no fix. I understand that this thing is a beast and I should just stop using it but, it is the only pc I want to clutter up with old games and stuff. And I know it is compatible because I used to play these games before.

Microsoft DirectX DSK Download:not Enough Free Disk Space?

Oct 14, 2010

After downloading a game, I found out I needed Microsoft DirectX SDK to make it work. I downloaded it but now it's telling me:There is not enough free disk space on drive C:The amount of free space required on the drive is 1, 124, 040,704 bytes.The space currently available on the drive is 612, 560, 896 bytes.
I've tried getting rid of as much as I could on my computer (Microsoft XP by the way) but it didn't make much difference. And I really don't have much at all on it either.

I recently added 2GB of RAM to the 2GB I already had installed. My system is showing the RAM as being there in my BIOS, but, when I run DXDIAG only 1GB is showing out of the 4GB I have installed . Is it because of the Windows version I am running and if so, what can be done?
