hi.
have a good day everyone
problem with the motherboard when I start it, the first start time beeps and after 2 seconds it turns off. When I examined the motherboard, the F7003 fuse was broken. i changed i didn’t get result
The values of all coils are normal. The CPU circuit is 1-2 ohm but not a short circuit. Because they have the same low value on the zen cpu value graphics cards
I measured the voltages of the active coils at the first start time with an oscilloscope. everything is smooth. all voltages in the coils are activated for 2 seconds. The current drawn is up to 7 amps.
Bios Eeprom Data Read the first start time
