Hi all -

I have had my system for almost 2 years with no problems. Here are my specs:

Dell Motherboard from my previous system
GTX 780
i7-2600
8GB Ram
Big case with 4 case fans

All of a sudden, in the past week or two, I have had the following problem, similar in incidence each time:

-My computer will run fine for a few hours
-All of a sudden, the screen will go black OR the computer will hang a loud buzzing of sound will emit from the computer
-Shortly afterwards, the computer will restart, sometimes to the Bios, sometimes just windows seems to restart, or it might just be happening fast because I have a solid state drive

I have used cpu-z and hardware monitors to check my temps and the CPU runs, on average, at only 55-65 C at full load, video card at 40-55 C

I ran a RAM test, and it seemed to indicate no errors

My power supply is new as of 3 months ago

I have an intel solid state drive, and did a chkdsk and got no errors there

Does anybody have any idea what is going?

When I go to windows reliability monitor I get livekernel errors 117 and 143
