View Full Version : Hardware Acceleration - Windows 7

12-01-2011, 01:25 AM

I have just built my computer today, and loaded windows 7 Professional 64-bit onto it. I am trying to play a game, and it comes up with the error 'A problem occured initializing DirectDraw. Hardware acceleration maybe disabled, please run DXDIAG.

So I ran this, but I can't change anything, and not sure how to fix this.

I have two AOC Razor e2043F 20" Monitors, and the video card is a ASUS Geforce ENGTX460 DirectCU TOP 1GB DDR5 PCI-E

Thanks in advance

Did you install the chipset / videocard drivers?? Right mouse / properties on the desktop / go into display settings / advanced tab. I would kill UAC as well. Its annoying

Sorry I'm running windows 7 not XP

I re-installed the driver, and my custom theme , which was red (but default before) has finally shown up red. But when I restart the computer it disappears again.

I re-installed the driver.

Which driver?
Motherboard chipset or Graphics?

You need both.

What version graphics & chipset driver are installed, and what power supply do you have?

If you have all the motherboard drivers installed and the latest graphics driver for your card then possibly DirectX isn't installed properly, you can get it from microsoft's update site I believe. Most games install directX or give you the option but not all.

I installed the latest graphics driver from NVidia '260.99_desktop_win7_winvista_64bit_english_whql'. What is happening is I'm installing the latest driver, and it works, but when I restart my computer it's disappeared.

What disappears after you reboot?? Have you installed the rest of the updates, including today's updates? Did you try the ASUS videocard drivers??

The nVidia driver I install, will fully install and my computer will work but every time I restart my computer it's as though it goes back to default. How can I check I have all the latest drivers? Windows update shows nothing new?

Go to the manufacturer's site, and download whatever driver

Thanks. I'm not sure where to upgrade my Motherboard drivers as I can't find them on the EVGA site. I have a EVGA X58 SLI 3 motherboard with an ASUS GeForce ENGTX460. I am currently installing the NVIDIA Graphics Driver V 260.99. I tell it to do a clean install and it removes all my profiles, then says 'installing graphics driver'. As soon as that comes up my graphics are correct. But that is what disappears.

Looks like theyre here (http://www.evga.com/Support/Drivers/Default.asp). Select mainboards then x58 series. Chipset drivers are at the top 3rd row

Works ok here with Opera. What browser are you using? If Chrome, as it says you need V9. This is the direct link ftp://ftp.evga.com/driver/INF_allOS_9.1.2.1008_PV.exe

12-01-2011, 10:24 AM
Oh. I'm using rockmelt which runs of the chrome. Thanks. :). I'll try IE.

I updated the chipset and my graphics have disappeared again.

Do you want me to have a look with teamviewer (http://www.teamviewer.com) ? If you do, send a PM to me, with the ID and password once you install it

Good news. I decided to actually read the Nvidia Forum board and found the following article. http://forums.nvidia.com/index.php?showtopic=169555. Followed it and it works perfect now! :D

Just to add, I usually don't recommend installing drivers from the AIB maker's site (such as EVGA etc) as they usually end up out of date.

Drivers direct from nVidia themselves will always be the most current.

Yea I found that out. Dam it stopped working again. I have now contacted nvidia directly. Thanks for all your help guys
