Windows 7 random crashes

I have a Windows 7 computer with this hardware:

• Asus P8P67 PRO
• Intel i7 2600k
• 8GB RAM
• AMD Radeon HD 6970
• 2TB HDD (used for storing data)
• 128GB SSD OCZ Vertex III (used for the OS)

The PC works fine but Windows crashes after some time (sometimes after an hour, sometimes after 4 hours, etc). I can see it because when I open an application, it hangs and doesn't open, and if I click on the start button, explorer crashes. After that, if I wait it goes to blue screen and re-crashes (never reboots): I have to shutdown and restart the PC.

Does anyone else have this kind of problem? I can't understand what it is and why it happens. I thought it could be that the space left on the SSD was too small but it has 17GB free.

After reboot screen (error code is 0xc000000e):

If it can help, here it is the SMART tool output (OCZ Smart Tool):

UPDATE

HWMonitor screenshot:

0xF4 means a critical process has been terminated. It can be either software or hardware and if you upload your DMP file to Skydrive or another file sharing service we can tell you which.

In the interim I would run a system file check (to check for software) and a CHKDSK to check the HD

Please run a system file check (SFC)
