I recently upgraded my computer and it will not post unless I jump the cmos connection. After resetting cmos, I turn it on and it brings me to the bios. Once I exit out and the pc restarts, it will turn on but it will not post. However, if I reset cmos it will post into the bios again. The issue is that I need to install windows however the pc will not boot at all regardless of what I do when I plug my USB flash drive in.

I have replaced the CMOS battery, my bios driver is up to date.

I’m suspecting I either have a faulty motherboard or my psu is not high enough wattage.

Specs:

CPU: Ryzen 5 7600x MB: Gigabyte b650m ds3h RAM: Corsair Vengeance 32gb GPU: RTX 3060 PSU: 500w unit

Update: Now when I reset the cmos and turn it on with the USB plugged in, the screen to enter BIOS appears for a literal second and disappears and the monitors loses connection.

    I would usually wait around 5-10 minutes until the other night when I just let it try to let it post over night. Still hadn’t post by the morning.

    Usually what happens is after I reset cmos the pc fans will power on and the a couple minutes later the system LEDs will turn on then a couple more minutes later the bios will post with the cleared cmos message. I usually just restart the pc but when I do that the fans will power on like normal but the system LED will never come back on and it will never end up posting.

    I’m almost certain it’s the motherboard after I saw someone on google have the same issue I just don’t have a spare motherboard to test it unfortunately.
