...As far as I could see, there weren't any obviously blown capacitors on the mainboard and the timescales mentioned didn't quite seem to match this system's generation. Its timescale's genesis is in motherboards. OTOH, PS development, production and QC are rather different from motherboards. It's apparently easier to get a PS to survive its warranty period with lower quality components, and in the process kill a motherboard that might have survived a better PS.
I've seen cases where a PS did not protect against a power surge. You would think that a switched-mode PSU would, but apparently not. Cheap components, poor layout.. Whatever.
ZAP!
That being said, what Peter describes _could_ be a wonky PS, and something that starts but gives up once a load actually hits it. its something I would consider. One of the advantages of the Closet is that there's always something there to cannibalise for some component.
Could be the spike from the HD drive(s) spinning up. Had something similar, on coldboot the system began to start (Fans spinning up, maybe the BIOS page showing?), then just hang. It turned out that the PSU (450W with not much on 12V) was not strong enough (anymore) to power up the drives (8-13, can't remember which box it was at what point). Solution: a solid (rather costly) 650W SeaSonic PSU (from Corsair). In a different case, the board would not boot rightaway, producing "nuiiiic-nuiiiic-nuiiiic - tick tick tick" sounds directly after switching on power (along with the fans spinning, IIRC). And it got worse. While at first it did start and run after a couple of tries (nuiiiic .. tick cycles), at the end, I think it took minutes of that before it came up. Oh, and it tended to shut down after a while (~5mins?) later. Turned out the MoBo was borked. Switched that (on guarantee IIRC :), everything fine since then. So much for symptoms re PSU vs. MoBo ;) For the Op: I put 60% on the MoBo and 40% on the PSU ... That is if the system stays on long enough for the HDDs (the spinning rust type) to have spun up. If it shuts down while the HDDs spin up it's 70+% on the PSU ... -dnh [1] http://www.tomshardware.de/netzteil-oem-hersteller,testberichte-240604-4.htm... -- Vala: Thank you.
