My PC crashes randomly

I reinstalled Windows 7 64bit and I updated everything. I used the same drivers I used before, which for 5 months worked perfectly. However, after reinstalling my Windows, my PC crashed and the monitor powered off. I pressed the reset button, but it would not reset. I had to hard-power it off. The crash occurs after 5min using Windows. I was not running any intensive programs, it was just idling.

I only used drivers from ASUS and Windows update, no other 3rd party drivers were installed.

I reinstalled my Windows again and it is working fine.

What could have caused this? Is it a sign that my motherboard or graphics card is dying?

Intel 3770K 3.5Ghz
16GB XMS 3 Corsair Ram
Sapphire AMD HD 7950 3GB
ASUS P8Z77-V motherboard
Samsung SSD 128GB
2TB Seagate HDD
Samsung Blu Ray drive

It could be faulty memory, double check the voltage and timings in the BIOS.

Also try running mem test, link below.

enable xmp for your memory too if it supports it in the bios

with 16gb look for vccio or vccsa system agent voltage (whatever one out of those is at 1.05v and set to 1.08v)

Also check Event Viewer for the crash dumps. You should get an indication of what is going on.
