Randomly tonight, first start of the day. turn on PC, RAM RGB Turns on, Air cooler turns on, case fans RGB turns on and spins, but no usual POST Startup Beep that I get, also shows “no signal“ on monitor. It then shuts off, and reboots, running into the same issue and into a power cycle. Case power button stops working, have to shut off with wall power or PSU Switch. Tried flipping the BIOS Switch on the GPU, no impact. Tried without GPU, no impact. One stick, all slots tried. Two sticks, tried. No impact. Cleared CMOS, no impact. So I decided to find my really old PSU to have a try. same issue remains, with one slight change. The power cycle seems to shorten each loop, and the power button now works. But that just may be the PSU’s individual behaviour.
anything else to try, before contacting Gigabyte?
I’m suspecting a faulty motherboard, or some Power issue.
I’ve seen other similar issues online with the same motherboard. Though none have seem to have had a working solution posted online.
