This PC was working fine. I put it aside for a few weeks, then switched it on, but little happens. Monitor does not come on,

hard disk no activity, not even a beep code. The only thing that happens is that after about 15 seconds, the fan speeds up.

I would assume that is under control of BIOS, or does it run from independent temperature controller?

I reseated all connectors and changed the CMOS battery, but no go.

So looks like mainboard is dead?It is fairly old (Sandy Bridge).

Unfortunately uses HP non-standard power supply, so I just cannot plug in a spare, like a sensible desktop.
