   I have checked both Sets of Ram, and they both give the 15,40,4F errors. They were Team Xtreme 8GB sticks TXD38G2400HC10QBK RAM, THEY WERE SET AT 666.6 MHZ And i set them for their correct 2400MHZ in the bios, then a week later, IE. now, and they both seem to have gone out... little bit depressed that they seemingly could not run at their actual native setting.They were at 1200MHZ dual channel incase anyone thinks i set them to run at 2400 straight out. :P

	I am running the z87 extreme 9/ ac mobo, i have unseated and reseated my GPU, CPU, Ram, and will now do a full test on the ram a second time. i have a shipment of ram comming in, a friend ordered them for me thank his heart, so i am hopeful to have a new set later today, i fully reset the CMOS once already after all of the reseats, but i will do this again with each remounting of the Dims.

	Given those POST codes, 15, 40, 4F, that indicates a memory problem. It is rare for memory to fail spontaneously, but it can happen. All it takes is one memory chip to fail, or if one of the DIMMs is not in its DIMM slot completely. Two things for you to do. Remount all of your DIMMs, and clear the CMOS/BIOS. If POST still fails, start checking the DIMMs for failure. Try one at a time in the slots farthest from the CPU in each channel. Try to keep track of which DIMMs you tried and did not try. Each time you change the DIMM or DIMMs, clear the CMOS/BIOS. What board are you using, and what memory?

	I would start by checking all your power connections, reseat all hardware and make sure your GPU hasn't popped out of the slot partially. If that does not help then try clear CMOS using this method and see it that helps.

Pc has been running for less than a year.
