Screen freeze after install nvidia 560 gtx next intel hd3000

It sounds like the nVidia card is displaying, indicating that the onboard graphics has been disabled.

My hunch would be some kind of system instability, maybe PSU?

What's the full system spec?

Motherboard : MSI Z68AGD65 B3
PSU Intel Core I5 2500K 3,3 Ghz with HD3000
Memory 8gb
win 7 64 bit
Graficscard :MSI N560 GTX

Dag zeilboot.  

Did you try older drivers yet ?

What does your system say about the graphic card, does it states it has two cards running or only your 560 ?

What does the bios says ?

I can assure you your PSU isn't a Intel Core I5 2500K Processor

The System only shows the 560 .
I did try the drivers wich came with the card but then the screen shows some waving screens en goes black. I had to start the HD 3000 again to get to my system (and remove the 560)
I am going to look in the bios. The HD3000 will be automaticly disabled I see in the manually

It s really! I read it in the system configuration to! Why not ??

Install again ALL the HD 3000 drivers, install Virtu Software (comes in mobo install disk)
And though Virtu software Disable the HD 3000 GPU, make sure the vga cable is on the dedicated VGA.

I had problems activating my SLI without doing this first.
Hope this helps you as helped me.

This is your CPU, not PSU  

PSU = powersupply.

Maybe try driver266. Helps with my 560Ti, though it seems only the case with my 560 version. It didn't help others yet, but trying can't hurt though.

I put pci the latency timer in the bios from 36 to 224 and now Ican work with it but not stable. There is a problem in the direct 3d 10 textureload assesment. I do't really not know what this is all about. no helpdesk give me a solution. I think I have to go back to the HD 3000. To Vitornob : the HD3000 is integrated in the CPU. How to SLI ? No way.

Hi,
You should NOT have to be messing around with "latency timer" type stuff.

Before anything else, you need to confirm that your POWER SUPPLY is adequate to the task. There are two things you need to confirm on your PSU:

1) The overall Wattage is sufficient for your system.
2) The Amperage for the +12V rail is sufficient for your graphics card.

Recommended bare minimum:
1) 600Watts overall
2) 24Amps on the +12V rail (read your manual to confirm the Amperage requirement for your graphics card and post this too)

If your Power Supply is not sufficient I can recommend one.
This one is a pretty good quality and value:

750Watt Total, and 62Amps for the +12V rail (for the graphics card)

If you would like, I can help you properly setup your system as it sounds like you may need help to get it configured properly, especially if you play games.

Anyway, please post your PSU name. We can Google the details but the model needs to be correct.

Coolermaster extreme power plus 500. According to a calculating tool it should be sufficient power for my configuration. I need 430 w.

You are right man. It is the psu! I took an other and the problems are over. The Coolermaster 500 gives not enough power. 500 is not 500 watt!

I knew Cooler Master ain't that great but never thought it was that bad.  

Check your mobo for bad caps as well
