Laptop screen goes black and everything freezes

I'm no GPU expert, but I think there are settings for resolutions and anti aliasing (AA).
EDIT: I've requested some more help for you Jo.

Jo... follow the post #2. upload the msinfo.nfo.

Maybe there is any clue.

Hi Arc,

There is a msinfo.nfo in post 3 - are you asking for a new one? glad to see you're on this. I won't be much help.

Sorry Slartybrat .... overlooked it

Now, let us have a look in it.

► First of all .... July version of ATI display driver .... one of the most problematic thing I can say. Update it. if there is no stable version available (not being a ATI user, I am not sure) use any available beta.

Code:

Name    ATI Radeon HD 3200 Graphics
Driver    c:\windows\system32\drivers\atikmpag.sys (8.14.1.6264, 351.50 KB (359,936 bytes), 04-Jul-12 8:10 AM)

During July, a lot of Crashes on ATI display driver we dealt. But now those disappeared.

► Ethernet driver, Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC. It also needs update.

Code:

Name    [00000007] Realtek PCIe GBE Family Controller
Driver    c:\windows\system32\drivers\rt64win7.sys (7.46.610.2011, 526.60 KB (539,240 bytes), 10-Jun-11 6:34 AM)

Get it from Realtek.

► Sound driver, Realtek High Definition Audio Function Driver is even old.

Code:

Name    Realtek High Definition Audio
Driver    c:\windows\system32\drivers\rtkvhd64.sys (6.0.1.5874, 1.70 MB (1,778,592 bytes), 17-Sep-10 8:55 PM)

Get it from Realtek.

► These programs ... can screw any system up.

Code:

Start Menu\Programs\DAEMON Tools Lite
Start Menu\Programs\PC Tools Registry Mechanic

Uninstall those.

Does it change anything there?

Edit: Missed one, that is important.

Synaptic Touch Pad Driver. Tool old.

Code:

Hardware Type    Synaptics PS/2 Port TouchPad
Driver    c:\windows\system32\drivers\i8042prt.sys (6.1.7600.16385, 103.00 KB (105,472 bytes), 14-Jul-09 2:19 AM)

Update it from http://www.synaptics.com/resources/drivers.

You are welcome, jo :)

As I have told, I am not an ATI user, I dont know about the availability of the drivers, but in many a threads, the OPs told me that there is a beta later to July. If you canot get it, get an earlier one, but get rid of this one installed.

only one cleaner I'd recommend, that is CCleaner.

Let us know how the system is working after all those.

Thanks Arc,
I might be to help more on the AMD/ATI issue - I might not be the best on this, but have solved a number of issues on my own machines using AMD graphics. Let's see what I can uncover.
For now I'll just post the reference sheet for jo's machine now while I do some research.

I do have one question for jo - do you recall where the current driver came from? I've had mixed results using Windows updates for hardware. sometimes WU gets it right, other times it gives me the wrong driver. It's probably a good idea to roll back the driver as Arc suggests.

More info:
AMD 780G chipset
-> Downloads: AMD 780 series - SB700 Chipset
-> Downloads: AMD 780G - ATI HD 3200 Graphics

Only vista drivers listed, the most recent are

01/09/2012 | 8.96 .| AMD Embedded GPU and Chipset Driver for Windows Vista®
05/30/2012 | 8.961 | AMD Legacy Catalyst Display Driver

Dont' do anything yet jo, I'm still looking at the information you suplied and what Fujitsu and AMD say.
