Is this a right choice for the Windows 7 hardware?

Till yet Windows 7 don't show such linings.
Can you please take my PC remote connection now?
I am working on WIndows 7 - X64 right now.

tomorrow I am thinking to go back to the vendor to relace the defective things, so if APU is also defective, then I will replace that as well.

At present on Windows 7, what I am seeing is, the video issue only, that low quality video becomes worst.
Do I need to replace this APU or need to buy a graphics card?

But sir, what should I say them to replace APU or motherboard?
In My Computer Properties, everything is showing as fine.

I believe the issue is related to the software, windows 7 seems OK..

Let's try one more thing...

Send a screenshot of the device manager and open up the video (or graphics) adapter, please.

Sir, I have Teamviewer installed, shall I start it? so that you can easily see the settings..?

Jovesharma, i'm not on my PC right now, and i really don't know how to use teamviewer, so let's stick to the thread to see if we can find the root of your issue

Sir, this is the screenshot of device manager and graphics

Apparently the driver is installed correctly.

I'd suggest you to take the PC to the place where you got it to see if there's something they can do... because everything seems correct, aside the windows XP picture that looks really weird.. Usually APUs don't need a separate video card, i've seen the same APU as yours running Dirt 3 at 1080p without problems! so i'm guessing... wait!

Download the portable speccy from here Speccy - Builds and post a screenshot of the main window, maximized please. I just want to check the Temps on your PC, that could be harming it.
