Sapphire hd 5450 not recognized, HELP  

One adjustment to what I mentioned above...

When you boot to safe mode, Device Manager -> Display adapter shows the identical name as it shows when you boot normally. Doesn't matter if you're in safe mode or not, the Display Adapter name will be the same.

So if the Catalyst drivers have been successfully and properly installed, the name shown will ALWAYS be "AMD Radeon HD5450", safe mode or not. This confirms that the video drivers for the HD5450 WERE INSTALLED SUCCESSFULLY.

However if the Catalyst drivers have not been properly or successfully installed, the name shown will ALWAYS be "standard VGA adapter" or similar, no matter whether you're running in safe mode or normal mode.

So if you currently show "standard VGA adapter" in Device Manager when you boot to safe mode, that tells us you do NOT have the Catalyst driver installed. It either didn't install successfully, or you've uninstalled it.

And that means you must also be once again using the original MS-provided vanilla generic VGA video driver, as you were right after the 64-Bit Win7 install completed and before you installed Catalyst (which runs in SVGA mode) and got into trouble with the black screen.

Are you now operating successfully this way, with "standard VGA adapter" showing?

Unless you replace the SMS19A100 with a newer higher-resolution monitor that can run in SVGA mode, I'm going to suggest you uninstall the Catalyst driver. The MS vanilla VGA driver is just as acceptable for your 64-bit Win7 as it was with your 32-bit Win7, which is what I suspect you were using in your previous 32-bit Windows setup.


I'm still wanting to know if you had Catalyst installed in your previous 32-bit Win7 environment.

Bro
I buyed all the stuffs but i didnt install. A well known person did it for me.

I installed amd catalyst in 32 bit

And yes it is running perfect with VGA standard monitor.

So you want to say is that my only way is to upgrade to a better monitor, right?

Did the builder also install 32-bit Windows for you? Or did he just do the hardware construction and you did the Windows install yourself?

You also didn't say if this machine included the HD5450 in its initial purchase configuration, or if you added the HD5450 after the machine was delivered to you. Did the HD5450 come in the machine from the builder, or did you add it yourself after it was delivered?

I installed amd catalyst in 32 bit

Again, was this done by you AFTER the initial machine was delivered to you?

Does that mean you added the HD5450 yourself to the delivered machine that didn't have the HD5450 in it originally, and then realized you also had to install Catalyst?

Or was it because the original machine DID have the HD5450 in it but came from the builder without Windows installed yet, and since you installed Windows yourself you also were installing drivers for all hardware in the machine, including the HD5450?

Now, are you sure you installed Catalyst successfully in your previous 32-bit Windows environment? Remember, if it DID install successfully then Device Manager would show it as "AMD Radeon HD5450". If it DID NOT install successfully then Device Manager would show "standard VGA adpater".

And yes it is running perfect with VGA standard monitor.

I'd like to see the specifics of your current 64-bit environment.

(a) Right-click on desktop, select "screen resolution". What is shown as resolution?

(b) Device Manager -> display adapter, right-click on "standard VGA adapter" and select Properties, select "Driver" tab. What is shown as driver provider, date, and version?

(c) Right-click on desktop. Does "AMD Catalyst Control Center" appear at the top of the popup menu or not?

I'm still not sure, but your machine is a real puzzle.

The specifics of your previous 32-bit environment need to be clarified. It's not clear if you were actually using 32-bit Catalyst successfully or not with your monitor running at 1366x768. If so, it's honestly a mystery why 64-bit Catalyst would not also work at 1366x768. The monitor hardware should report its native/recommended resolution of 1366x768 to the drivers at boot time, no matter whether you're running 32-bit Catalyst or 64-bit Catalyst.

But if you actually were still running with the MS generic VGA drivers in your 32-bit environment because Catalyst didn't actually install successfully (with Device Manager still showing "standard VGA adapter"), then your 64-bit results would appear to be the same as your 32-bit environment, with successful operation only when staying with the MS-provided generic VGA driver.

So yes, it really would be informative if you had access to a newer, larger monitor with resolution of at least 1600x900 or 1920x768, and then try to install 64-bit Catalyst 14.12 again.
