Question about ECS RS400-A (V1.0) Motherboard
I just installed a new ECS motherboard into an older 98 machine. I am pretty sure I have everything plugged in but when I connect the power to my computer there is a high-pitched whistle sound, not very loud but not hard to hear, and the noise continues when the computer is turned on and the POST will no appear. The Screen stays black. Help!
The noise must be coming from the power supply. The only thing running before you press the power on button is the PSU.
Unplug the power cord on the PSU. Check the back of the PSU for a red slide switch. Make sure it is set for 115v. Than disconnect the main power from the motherboard. Plud in the power cord, (still hear the high pitch noise?). Swap out your power supply.
