It's rare, but it happens every now and then. I'm just regularly using my computer, then out of nowhere, it freezes and just stops responding. I'm forced to restart. But when I restart my PC, I can't start windows because it says "Disk Read Error, Press Ctrl+Alt+Del to restart".
The only way I can fix this error is by completely turning off the system, waiting about 10 seconds, then turning it back on. After that, everything is back up and running just fine.

This is a sign of an impending failure. Do a Google on the error message and you would find out the same thing. I would recommend a a new HDD back up everything on it. And use this is a secondary drive.
