Hi all - I have a build advice thread elsewhere, this is for troubleshooting. I suspect this forum has slightly higher traffic, always used to before. This is my build: Aerocool xPredator Evil Black MSI GD53 MOBO equivalent - it's an old replacement when the MSI board died before Intel i5 2500k @ 3.30ghz Be Quiet Dark Rock Advanced 2x 2TB Samsung Spinpoint F4 Crucial M4 64GB Samsung Evo 512GB Corsair Vengence 8GB DDR3 1600 MSI twin Frzr R9 290 EVGA 1000w GQ Gold LG IPS231P x2 Sidewinder X6 CM Storm Sentinel Advanced Logitech Z-5500 My signature was my old build before my GPU got fried, and then later on my motherboard died. I don't know exactly what it is, but it's the same chipset that would allow me to keep my DDR3/CPU, and was like £30 replacement. That was 2-3 years ago. I just checked the barcode, and I see it is a G-12528 Intel chipset board. Now. I have a computer that suddenly doesn't power up at all. The only evidence of life is the green mobo light. I shut down one night as normal, next day couldn't start. I run win 10 64 bit. I have tried jumping the start pins on the mobo in case it was case button fault, but to no avail. I do have a spare Antec 650 that I have tested but again nothing, no power at all, zilch. I reckon MOBO is dead - it was gotten second hand to prolong the life of the rest of my build, and there wasn't much else available. I don't have a spare system to check CPU or RAM, which I'd like to keep to build a spare PC - I have been out of it for so long that I just can't tell now what chipset or motherboard to get (or even if this is possible), nor how to test those parts without one. Some help would be nice in figuring out why this happened all of a sudden, and any assistance to check anything else to confirm or disprove my suspicions as above.
