New computer lag when booting Windows 7

Lately I've composed my new computer. But I have often a problem with the following scenario:
-> after turning on computer, the system (Windows 7 Professional 64-bit) is not getting up (I see a black window)
-> I restart my computer and select the boot in normal mode option
-> the system is getting up and I see this:

enter image description here

-> I'm restarting my os again and it works fine

What can be the problem?

My computer specifications:

CPU: Core i7 870 2.93GHz LGA1156
motherboard: Gigabyte GA-P55A-UD3
graphic card: Asus GeForce GTX 470 1280MB DDR5/320bit
RAM: Kingston HyperX KHX1600C9D3K2 4GB
PSU: Corsair 650W CMPSU-650TXEU BOX
HDD: HDD Samsung 1TB HD103SJ

Video card problem in my opinion. Did you connect all the power connectors to your VGA? (okay if you don't connect them it wouldn't even power on.. ignore this stupid idea, just contact reseller!) If yes, you should contact the reseller about warranty. (Seriously this is not a simple driver issue or anything like that.)

Agreed. Try another screen as well, just to be sure. – None – 2010-08-05T20:28:46.560

Yeah.. it won't hurt. (it looks like the screen is perfectly fine.) – Apache – 2010-08-05T20:45:14.560

The screen is new and is working fine with my laptop. It might be the graphic card, becouse after and during driver installation I had the biggest problems. I wrote to Asus support, let's see what they say. Thanks anyway. – czerasz – 2010-08-07T16:21:04.263

So after over one month I'm happy to work on my computer.

What happend? Actualy nothing. The card was tested by Asus and they fond nothing (about 3 weeks). I gave the whole computer (with periphery devices) to the service (3 days) but they also found nothing. The problem, I noticed was only at my home.

I took every electrical device which was not connected to the computer away, I switched to another socked and the problem is gone.
