[Cialug] OT: USB Issues

[Tim Wilson]

Resurrecting this old thread, need some more help. To get up to speed,
there was a lightning strike near my house in October.  There were 3 USB
devices hooked up to my gaming tower, not including the KB and mouse.  All
3 were fried (KB and mouse seemed to be ok).  The computer continued to
work, but I was  afraid to plug in anything to the USB ports.

In March,  I finally decided to send the motherboard into Gigabyte for
warranty repair.  To my surprise, they said there was nothing wrong with
it.  After getting it back, I let it sit for a couple of months, I wasn’t
looking forward to putting it back together.  That was the reason I bought
a pre-built PC.  I made a mistake in taking it to Best Buy, they said they
would reassemble it for me.  Thanks to a recent appliance purchase, we had
their Total Tech, so there wasn’t a charge to assemble it.  I assumed it
would be back to either full working order, or at least back to what it was
prior to sending it in for repair.  Instead, they said it wouldn’t boot.
Of course, they wanted to sell me a new setup.  I decided to bring it home
and take a look at it.

I thought maybe it would be a bent pin on the processor, or something I
could figure out.  Unfortunately, I’m stumped.  I don’t know if it’s the
MB, or processor.  I don’t get any beeps, even without RAM.  I need to
either buy new parts, or get it diagnosed.  Does anyone know of a place I
could take it to get it diagnosed?  It’s a Gigabyte MB, AM4 Socket, Ryzen 7
processor, not quite 3 years old.

TIA!
