Screen becomes zig zag like 8bit video game crash and...

Hi I am using win 8 pro with media center, Screen becomes zig zag like 8bit video game crash and stops responding after few minutes. Unable to find the reason, hence i decided to install a release preview which was installed on my working laptop. After installing release preview still the same repeated.
So i thought of hdd issue, and i replaced another partition with win8, previously this partition contains win 2008 and was working good. still the same issue persists.
I viewed the system log, a critical reboot error is showing up after an event of information saying "File System Filter 'npsvctrig' (6.2, ‎2012‎-‎07‎-‎26T07:57:33.000000000Z) has successfully loaded and registered with Filter Manager"

Hardware: Nvidia geforce7025/nforce 630a
MoBo: Asus
Sound: VIA HD audio

Please Please Please throw me a light on this error, i love windows 8 but still crashing like hell.

Can Some body please answer my question or give me a hint on this please!

Please clarify what you're doing when this issue takes place. We don't really have anything to go off of, yet. All I can suggest at this point is to make sure your video drivers are updated.
