Re: Short on motherboard Gigabyte GA H97 Gaming
Most likely the motherboard has a shorted MOSFET on the CPU VRM (probably an upper MOSFET.) Either that or something wrong with one or more of the MOSFET driver(s).
Of course, before doing anything, first remove the CPU and check for bad pins in the CPU socket. If none, keep CPU off the motherboard and perform following test with multimeter (with PSU disconnected and unplugged from motherboard): put positive (+) multimeter probe on 4/8-pin CPU connector (12V rail) and put negative (-) multimeter probe on a ground screw. What resistance do you get? -

Hello people! good night, how are you? I tell you, a few days ago I started with the repair of the Motherboard Gigabyte B550M Gaming rev 1.0, in question and I could not find the schematic on the internet, If any of you have it and it would make it easy for me I would be very grateful! I thank you in advance!

by Geeker007Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?
I am new to electronics repair, so my queries could be naive but I am ready to learn.
So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is... -
