PC Won't Power On, Is My Motherboard Toast?

[mistermitra]

My PC won't boot at all. No lights on the motherboard (or anywhere), no POST, zero signs of life. I've tested that the power supply works with the paper clip test. I've tried the tips on the sticky with removing the various components but still zero signs of life.

The PC was working fine until I plugged in a flash drive one day and it crashed hard - completely powered off. When I powered it back on it would show the motherboard splash screen (don't think it POST but it's been a while ago) and then would turn off again. I turned off the power supply, unplugged it, and plugged it back in but it wouldn't turn back on again - the state it's in now.

Is there any hope for my or is my motherboard just toast?

Can you check the pins of USB where did you connect the flash drive? Soo, otherwise i would try to change PSU in first place to eliminate that issue otherwise it could be dead motherboard.

Hmmm the USB port does appear damaged. It's on the front of the case. Would that really prevent my computer from powering on? And yeah I tried replacing the power supply, no difference sadly.

Then disconnect the front panel and try to boot.(just usb port)

Woooooooow! It fixed it! No way...

I'm so happy but wow I never would have believed that's all I needed to do to fix it... wow computer sitting there for months thinking it was toast just had to unplug the front usbs from the motherboard. The flurry of emotions I'm feeling right! Thanks so much I was just about to give up on it.
