Windows 7 BSOD help

Hi Experts,

My windows 7 Ultimate has been showing this bluescreen constantly.
I am not a computer expert. But I do know how to format/re-install Windows 7 on my computer.

I have formatted + re-installed the computer twice. The computer still constantly gives me this bluescreen.
This happens even without installing anything other the drivers.
***The computer is a dell Inspiron6000. Windows 7 installs all the drivers automatically through update EXCEPT THE AUDIO DRIVER. I did a quick search online and people have reported it would be fine to use the driver for Vista on Dell's website. So for the audio driver, I manually installed it. Not sure if this would be the cause. Otherwise, nothing else's installed.

Also, I did ALL the Windows updates, optional + recommended.

Any idea what I can do to pinpoint the problem so I can solve it?

I have attached photos of 2 BSOD.

Thanks 1st time BSOD After Fresh install + Audio Driver

This is the 2nd instance of BSOD
Stop 07A usually indicates a problem with the hard disk subsystem -- disk or controller. Use the Dell built-in diagnostics to test hard disk (Press F12 during boot on most Dells).
