8:61 p8h61 works well, yet it turns off after just five seconds upon powering up.
I recognize the issue by examining the debug card and the screen that briefly attempts to display the splash before turning off again. When I power it on (activate the PSU), it turns on instantly without needing to press the power switch, but after about five seconds it shuts down permanently, refusing to restart even if I manually activate it. It powers up within a second of the PSU being turned on, which could indicate a short circuit causing the unit to start up, though I question whether the board would try to boot otherwise. If that’s the case, I suspect it’s simply powering off and not functioning properly. The only solution I’ve tried so far is resetting the CMOS by adjusting the jumper, then returning to normal operation, which restarts immediately. This process can be repeated as needed. I’ve already considered draining the board and submerging it in water for cleaning, but the problem persists (fixed via a BIOS reflash). It seems unclear what further steps to take besides potentially selling it. There doesn’t appear to be any visible physical damage.
Verify CMOS power level. Certain chipsets react poorly when voltage drops or vanishes entirely. Others remain unaffected.
