I have a rebuild that replaced my previous desktop build where the EPU melted (I had to scrap the motherboard and 1000W semi-mod power supply on that one). Any way - I put this new machine together about 3 months ago using the processor, memory, cpu and chassis fans from the previous build. It has been working seamlessly since it was put together. No heating or whiring issues or anything at all. Very happy with it until today when it just switched off by itself - total power off no shutdown. I tried the power switch and it started for about half a second (looks like the chassis fans and CPU fans start, then the system switches off). I removed the connections for the hard drives and retried - same thing. I also tried removing all the ram - same issue; I then replaced the video card - same thing. Not sure if anyone has any ideas at this point. I could try replacing the PSU and see if that works but was wondering if anyone has any further ideas. Thanks in advance.
