How to Have only one video controller driver in windows 7

<snip>OK, what do you think of the information that's missing from the lower one here,

How to Have only one video controller driver in windows 7

That was taken from his msinfo32.nfo in his BSOD thread.

Not sure what information is missing from the "the lower one"? Please clarify. The msinfo code snippet shown in your link confirms the OP's Intel graphics card has 2 controllers which is why we see 2 display adapters in Device Manager (just as described in the Intel post).

Here's what I see. The msinfo snippet from your post shows 2 device install entries. The upper one includes line item

Code:

INF File	oem2.inf (i965GM0 section)

the lower one includes line item

Code:

INF File	oem2.inf (i965GM1 section)

The driver INF file name is the same for both (oem2.inf). That tells us both devices use the same driver. (A driver INF file includes directives telling Windows how to install the driver for the device) But notice each device shows a different INF section name: i965GM0 vs i965GM1

A driver's INF file is often divided into sections. Each section having different device install directives for Windows. Example: A single device driver might be used to install to install the device on either x86 or x64 architectures. But x86 and x64 architectures often require somewhat different install instructions. So each architecture has its own section name in the INF file. The Windows installer is smart enough to discern what section to use when installing under different conditions.

In this case we are also seeing a single driver for the Intel graphics card. The driver INF has a different install section for each of the 2 controllers. i.e. the single graphics driver is designed to install 2 controllers on the card

I also see the driver is version version 8.14.10.1930, dated 9/23/2009 so suggested the Intel Driver Update tool

Yeah, thanks for all that. This is what I'm talking about,

You don't see all the Not Available entries? Compared to the other one,

I'm not disagreeing with what you said previously I just thought it was odd there were all those entries.

So, that means what should i do now?

and hey addram, i found one ram which says its 4gb ddr2 laptop ram??

i mean like 1x4 gb?? so is that good?

@Vishalshetty
Next step is to use the Intel Driver update tool. See if it finds a more recent driver for you.

@derekimo
As to why the missing info for the lower one (the 2nd controller i965GM1), I don't know why or know that level of detail.

So I googled to find and compare the data you found in this case to another (I found the msinfo data for another case HERE) It shows same info also missing in the lower case, which is for controller i965GM1. So, don't know why, can only guess that's just how the data is for controller i965GM1 (Maybe the 2nd controller doesn't need that info? IDK just a wild a** guess.

@AddRam
So why the BSOD? That's an excellent and still remaining question. In disclosure: Although I've invested time trying to understand Windows drivers, I've spent very little time investigating BSODs. But I'll have a go at this one and post back if can find any suggestions to try

What we do know at this point
1. Seeing 2 graphics adapters in Device Manager is a red herring. At least for Windows 7, we now know that's exactly how things should appear
2. OP should next try the Intel Driver update tool and tell us the result

I also had this bsod issue in windows xp where there was 2 graphic cards just like windows 7 and it was crashing!!

i downloaded the intel driver update tool but it seemed to get stuck everytime it tries to get installed.

You having same problem before doesn't bode well And the Intel driver update tool hanging is also strange. Don't know if that could indicate a different problem? IDK

You could try installing in SafeMode - so your other programs aren't running if they're interfering with the install. The Windows installer doesn't normally run in Safemode so you need do a little work first

Do you know how to copy text from a paste and right-click to paste in a command prompt window? (makes safemode setup easier) But is up to you if you want to copy/paste or just type things by hand Command Prompt - Copy to Clipboard

I didn't read AddRAMs earlier posts about memory closely until i read his last one. Then I went back to re-read. I also pulled up the Acer manual for your Extensa 5620. I think AddRAM is onto your problem! (Certainly A problem)

The system spec in your profile says you have 3GB memory installed? I don't think that's kosher per Acer manual. I'm not a h/w guy so think AddRAM should be able to better comment. But sounds to me if you have 3GB installed that's not to spec and your problem could be memory as AddRAM pointed out
