Hello everyone, I have a problem with my pc. Yesterday I built my new pc with a MSI B650 Tomahawk Wifi, 7600x, 7800xt and 32 gb ram 6400mhz. Today I followed a guide to the undervolting step by step but from the moment the pc rebooted it doesn't boot up anymore. When I try to turn it on, a yellow and red lights appears on the mobo. I have tried multiple things: Flashing the bios with the usb Removing both ram sticks and using only one Disconnecting all cables to psu Used a jumper to reset cmos Installing new ram stick Changing ram slot Removing the AIO and apply new thermal paste (all the pins on the socket are ok) Nothing of this worked. Do you have a solution for this?
