Hey everyone, I have what seems to be a very weird problem... Just built a new system using a ROG Strix X470-F. Specs are:
ROG Strix X470-F Gaming
AMD Ryzen 5 2600x
16Gb G.Skill Trident-Z DDR4 RAM
Sapphire Nitro+ Radeon RX580
DeepCool Captain 240 EX RGB AiO Cooler
Corsair RM750x PSU
Samsung 970 EVO 256Gb NVME M.2 boot drive
Samsung 860 EVO 1Tb SSD
So here's the problem: the system boots up fine, but when it gets into Windows (10), I get a message saying, "Warning +12V voltage 3.313v"
Checking the voltages as displayed with AI Suite, it shows the +12v value as 3.313v, and the 3.3v value as 12.099v. In other words, the +12v and 3.3v values seem to be interchanged. The system will run fine for a random period of time, then the screen will go black, and the system locks up, requiring a hard reboot at the PSU to start up again. And here's some more weirdness... The voltage values as displayed in the BIOS are correct. I swapped out the PSU for a known-good one from another system (same wattage), removed and reinstalled my graphics card (which had been running fine in another system prior to installing it in this one), checked all power cables and connections, and even tried clearing CMOS. I flashed the BIOS to 4011 as soon as I had completed the build, so old BIOS is not the problem. Heck, I even flashed it back to the earlier version just to see if that would do anything, which it didn't. Anybody out there have any ideas? Thanks in advance for any help.
