So I was just browsing the net when my pc suddenly crashed. The fans began to spin super fast. It rebooted but the screen was blank. I unplugged the hdmi cable and put it in the CPU port, screen turns on now, but the pc still crashes everytime it gets past the windows screen.

Ps. I was playing CIV V just before browsing the net, but my fans were on high and heat didn't seem to be a problem, but it was also a fairly hot day today.

Please help :(

The gpu and psu are months old, other parts are 2 years old.

Little dust recently cleaned.
