Blank Blue Screen (Not BSOD)

Okay, I have a problem involving my computer.

It's a newly built machine, say, about 2 weeks old. Custom built of course.

I'm running Windows 7 64 bit Ultimate edition.

The problem is that whenever I turn my computer on in the morning/afternoon after it's been shutdown for the night it eventually crashes and brings up a blank light blue-ish screen. No text, nothing. It doesn't seem to be BSOD.

This usually happens 5-10 minutes after I've been doing something like browsing the internet. And when I turn my computer back on, I get the "Windows has shut down unexpectedly" and I'm given the option to run in safe mode, normal, etc.

When checking the event logs, I'm always given a critical error when this happens:

I assumed this was a motherboard chipset error. Which would make sense, since I forgot to use the installation disc that came with my motherboard. So, I dig out the disc and insert it and install everything it recommends. So, here I am thinking I'm all set to go.. But, when I turn my computer on this morning, while checking the weather (snow ), my computer once again crashes into this blue screen. I don't know what to do.

Any help would be greatly appreciated. And I will supply any more details if needed.

Thanks.


Edit: Oh, I forgot to add, the Computer works perfectly after I start it up after the crash. Everything works fine, until I shut it down and boot it back up several hours later. I can even put it to sleep and wake it back up with no problems.
