I built this computer in 2011 from parts ordered at Newegg.
Processor: Intel Core i5-2400 Sandy Bridge 3.1GHz
Graphics Card: XFX HD-697A Radeon HD 6970 2GB
OS: Windows 7 64-bit SP1
Motherboard: ASUS P8P67 Deluxe (REV 3.0)
Ram: G.SKILL Ripjaws Series 16GB 4x4 240-pin DDR3 Model F3-12800CL9Q-16GBRL
Power Supply: OCZ ZX series 850W
Display: ASUS VK278Q connected through HDMI Resolution 1920x1080
Driver: Catalyst version 13.1
At random times while using the computer, be it web browsing, youtube, or playing games such as League of Legends or World of Warcraft, the screen will go black and says no signal, the video card fan will ramp up to 100% and will stay that way until I turn the computer off. Even while the display is off I can still here whatever I was watching and can still here whatever game running. It also seems to be occuring more frequently within the past month.
