Asrock B75 Pro 3 no start

System has been sitting for awhile. Disconnected everything from mobo. Removed ram sticks.

When I power on the power light comes on and the CPU fan spins for a second. Then it stops and the light goes off. Then the light comes on again and the fan spins again. Repeats until I kill the power at the power supply.

No beep code.

Ideas?

Ideas?

Yes, try another Power Supply and see if the problem is cured.

Swapped out Corsair CX500 with a Cooler Master Silent Pro 1000. No joy. On a whim I replaced the CMOS battery. Voila! Old battery tested at 0.3 volts.

All of this just to wipe some Iomega Jaz and Orbi disks before I list them on eBay.

Some people on here have tried to tell me, that the CMOS battery is ONLY for storing settings, and that its not intimately tied to actual booting. I disagree, and this example supports my viewpoint.

Some boards are like that, and some will boot up just fine without a battery.. My experience seems to indicate that it really just depends on the board.

Likewise, some boards can be powered-up, with the CMOS jumper in the "CLEAR" position, and some boards, it will actually literally damage them if you ever do that.
