For the last few days my computer has been turning itself off randomly. There' been no warning like a BSOD or anything like that. At first it just happened when I was burning a DVD, but now it can happen any time.
Here are my PC components: PSU - Seasonic 500Watts
Processor - Intel® Core2 CPU 6700 @ 2.66GHz 2.67 GHz
Motherboard - ASUS P5N-E SLI
Graphics Card - VTX3D Radeon HD5450 1GB PCIe DVI HDMI 2GB
Optical Drive - Sony AD-7240S-0B 24x Internal DVDRWRAM SATA Black Bare
Hard Drive 1 - 500GB Western Digital Caviar Blue
Hard Drive 2 - 3TB Western Digital
Hard Drive 3 - 2TB Seagate Barracuda
RAM - Kingston 2 x 2GB PC2-5300 DDR 667 240Pin; 2 x 2GB Unbranded
I'm using Windows 7 Ultimate.
Please can someone suggest how I can stop this from happening?
