Evening tech tippers, Got a tricky one and hoping you can help please! Quick bit of back story, this is a PC I was using for several years, that then went into storage in the corner of my room when I built a new PC for a couple months before being given to a friend. It was working just fine when I stopped using it and aside from a dead ram stick/slot (not sure which but could not get all 4 sticks working no matter the config so dropped down to 2) has been working fine for my friend for about a month. He turned it off last night, after a sesh, tried to turn it on today and bupkis! The fans don't spin and the powerbutton LED illuminates for about 1 second before turning off. Unfortunately he lives in Yorkshire and I'm down in Hertfordshire so struggling to diagnose remotely. So far he has tried a different power supply to no avail and has tried powering on with literally nothing attached, no RAM, no drives and no GPU, this got us slightly further, fans span up then quickly slowed and stopped then it shut off again. I'm thinking mobo has died or there is a short somewhere. Looking at getting a replacement mobo, but wondering if anyone has any experience with anything like this, could it be something else? It's new to me, boot issues has either always been nothing at all or fans ramp up then shuts off, this weird leds on on then immediately off things is a first. MB: Asus Z97-A CPU: I7 4770k PSU: EVGA 600w GPU: GTX 1660 RAM: 8GB Corsair Vengeance 1600mhz Cooler: NZXT X60 Got a video of it happening, CPU block is missing it's plastic cover, that fell off years ago and has never bothered it. https://drive.google.com/file/d/1q5yuJQo...share_link Thanks

It happened to me a few years back. Probably a brief or faulty PSU, though you dismissed that idea. I experienced the same problem, but my mistake was a bent pin in the DIMM channel on the motherboard causing a short. It might have been avoidable if I had noticed sooner. The damage could be fixed or it could stay. If it keeps happening, the most likely cause is a short circuit.
