I've been building PCs for more than 40 years, but this is a new one on me. The system worked perfectly for about 25 days with no problems, installing and running about 10 different Linux versions. One day, I powered it up. It ran for about 20 seconds or so, then spontaneously powered down. After 10 seconds, it powered back on and continued to stay powered on for at least 10-15 minutes before I shut it down. No video output came on and the system never posted. I thought it might be the power supply and changed it out for a new one. Got exactly the same results.
Hardware is a Chinese X79 motherboard with a Xeon E5-2649, 16 GB of DDR3-1333 RAM, and a 512 MB M.2 SSD. Cooler is a Noctua tower cooler with a 120mm fan. Power supply is a Raidmax Vortex 635W (the old one was a Raidmax RX-630SS). Video card is a Nvidea GT740 SC.
As I said, it worked perfectly for nearly a month. So, how screwed am I?
