How to disable 3d acceleration on windows 7

[keitho18]

My ATI Radeon Mobility HD 4200 Continually crashes when running 3D games, I assume this has something to do with Directx (Direct3D) I currently have my 3d acceleration set to on, and cannot find how to disable it?

I Assume this is the issue? Thanks in adavance!

In Dxdiag.exe Under the display tab it has all 3 options enabled, without the option to disable them, is there any way to fix this?

We'll need more information on the crash, please. Blue screen? Hard freeze? Any specific error messages?

 

[keitho18]

Was a hard freeze, had to hold power button in until it turned off then turn it back on, happens with ALL 3D games including some web browser flash/unity games.

 

[Herr_Koos]

Are your drivers up to date? Can you check temperatures to make sure nothing is overheating?

 

[keitho18]

My drivers are up to date! How would i go about that? I don't think it should be overheating however? Better to be safe than sorry i suppose!

How do i do that?

 

[Herr_Koos]

CPUID HWmonitor is a good place to start. It monitors various system temperatures.

 

[keitho18]

The temperatures normally are around 51 degrees and when i run a 3D game it ups to around 56, i then closed the game fearing it crashing, is this normal? if so any other ideas? I swear it is something to do with 3d acceleration, can you permanently turn that off with everything?

Go to the "Screen resolution" display (from the right-click on Desktop menu), click on "Advanced" and select the "Troubleshooting" tab. This may, depending upon your card, have options to let you turn off various features of your video card.

 

[keitho18]

Yeah I Tried that and unfortunately my GFX card doesn't allow that, thanks for trying though

any other ideas?

 

[Herr_Koos]

56C is well within specification. You failed to mention whether this is for CPU or GPU though. Also, how do you plan to play anything if you turn off 3D acceleration?

 

[keitho18]

That was for CPU GPU was lower again. around 45.

The games i'm trying to play are simple games that hardly use 3D graphics.

Wish there was just a simple untick box...

Have you tried rolling back the driver to an earlier version? That seems to work for some.

 

[keitho18]

Yeah unfortunately tried that also, didn't work

 

[WR2]

Lets look at these games..... what are they?

 

[keitho18]

One in Minecraft another is 'Cultris' I also cannot run NBA2K10

 

[WR2]

Also.... are you using any Compatibility Mode settings?

 

[keitho18]

I tried both in XP compatibility and not, neither seem to work. however all 3 games used to run fine.

 

[WR2]

The would run fine under Windows 7?

 

[keitho18]

yeah i know they used to run fine, until this graphic glitch recently.

 

[WR2]

So you've pretty much ruled out DirectX as being the culprit.
And since you tested rolled back GPU drivers it's not video card related either (IMO).

 

[keitho18]

hmmmm yeah, any ideas what it could be then?

 

[WR2]

Lets check and see what might have changed recently.
Run the Control Panel Programs option. Use the Uninstall a program choice.
Go ahead and click on the Date Installed column till you have the most recent installed stuff showing.
Find anything installed around the time your games stopped working?

I installed NBA 2K11 around when it stopped working, it installed some new directx program that seems embedded in my computer, (as i have formatted it since).

I'm really unsure what it is sorry.

Need to be more specific here. You formatted since you first had the problem, but are now still seeing it? Logic suggests then that it must be hardware or driver related.
