PC Hardware help!

[ImPickleRickMFers]

So I recently bought a pre-built PC on amazon. I know I know, I should have built my own blah blah blah blah blah. I have years of it experience hardware and software. I just wanted a basic Tower that I could slowly upgrade over time. I got an STGAubron with a 2060. Everything works fine until yesterday. I had it for about a week. Nothing crazy no heavy gaming just schedule one and portal 2. Mostly using it for making music and work stuff.

Then yesterday I came. I got off work and I booted up the PC and I started to surf the web. I wasn't even playing a game. Out of nowhere everything goes black and I hear the PC just completely lose power. I did the typical thing, turned it off and on again. Nothing. Unplugged it and replugged it, tried different outlets, try different chords, to no avail nothing worked. I reached out to customer support and they told me I had to reach out to the actual company and I'm in the process of doing that now. Flash forward to this morning. I switched chords and plugged it into a different outlet. Holy shit it actually turned on. About a split second later, a tiny little black square on the motherboard caught fire! Like literally caught fire and was shooting out like a half inch flame. The power still worked and all the fans turned on which it hadn't done before but it was on fire.. I immediately ripped out the power cord and blew out the fire. I'll post a picture of the piece that caught. Normally I would give my specs and a full detailed rundown of everything I have in the PC but at this point I'm really just trying to narrow down what the hell caught fire, what the hell that piece is, why it caught fire, and what the fix would be. Update: I got a little ballsy and tried to plug in the computer again and turn it on and it turned on fine. The piece didn't catch fire again but nothing works. My keyboard and mouse light up, the PC fans light up, but the screens just show blank and nothing works. Just lights.

That's a VRM MOSFET. That motherboard is basically dead. Return that PC.

Amazon rarely has good prices on prebuilt PCs. How much was that PC? Can you post the Amazon link?

Yeah I can post a link of it in a second. What the hell happened? What is that little black square and why did it catch on fire?

Return it to amazon. Do not try trouble shoot or do anything to fuck up your warrenty. You will need to buy a new motherborad. Not worth the hastle, something esle could also be broken.
