Motherboard dead?
Discussion
Before I chuck a load of money into a new motherboard, CPU, heatsink and RAM, has anyone come across this symptom of motherboard failure?
Pressing the start button turns the PC on for a fraction of a second. The lights come on, fans spin and it goes off instantly. It doesn't even have time to show a POST code on the motherboard. Nothing on screen.
I've tried disconnecting everything, tried a different power supply and power cables, CMOS reset, tried different RAM sticks in different slots, tried running it outside of the case in case there was a short circuit. Disconnecting the case cables and starting it with the motherboard button. I've even tried a different CPU.
Exactly the same thing happens regardless of what I try. It's an old X-99 board (2016?), so well overdue for full upgrade anyway, but I've never had a motherboard fail before.
It's not a PC I use very regularly and the last time it worked it had lost the CMOS settings so I assumed it was the battery going, but perhaps this was a symptom of something failing in the motherboard itself?

Thanks for the replies. It all looks ok, no bulging capacitors, motherboard cables both connected. It was running fine up to the point that it wasn't.
Annoying as I only rebuilt this PC a few months ago using parts left over from from my brother's recent upgrade and I bought a used better CPU for it.
Maybe it's time to bite the bullet and do a proper upgrade rather than throw money at 9 year old components!
