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 (some people adviced me about it because of.high temps) 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 Removing the battery Changing thermal paste of cpu Checking pins but nothing helped. Any help?
