Hi all,
so, i just moved all the parts of mypc in a new case, and when i turn it on, everything starts but after a few seconds it turns off and then back on by itself, and enters this loop... i've tried to boot without the gpu, without ram sticks, without hdd, just mobo and cpu , nothing changes..
i've removed the mobo ,looked under it and it has a little scratch over some circuits, i might have damage it when i moved it in the new case.. is this the problem ?
