You should start with this:

RAM - Test with Memtest86+

However, I notice you are using an ASUS OEM on a retail motherboard. The only way that is possible is if the installation uses a hack to bypass the Windows validation check. Using these counterfeit installations can cause all sorts of problems, so I recommend installing a genuine Windows 7 first. Many BSOD analysts won't bother trying to solve issues when the installation is suspect.

I notice you had a different, but still counterfeit installation here too:

Its time for you to go genuine.
