Hi I get a black screen when I boot up my system. My computer gets hot and I get a blue screen when I hook up my computer to an external monitor for a little while. The stop code reads: video tdr failure. It wants to reboot and the black screen comes on again. I perform the test where you touch the D key and start button at the same time and the system does show 4 colors. I also performed the test where you touch the FN button and start button and the system beeps in this pattern: 3-1-4-6 beep.
It can due to when the CPU gets hot. By getting CPU hot sometimes CPU doesn't work properly, that why experts say to keep the computer at the cooler place. If after cooling down CPU doesn't work then the CPU or the window might be crashed.
