Hi all,

I'm working on building a mini PC and I've run into a bit of a problem-- when I turned it on, there was no image on my monitor. After a few seconds, I noticed the CPU fan spinning really fast and fairly loud, as well. About a minute later, I noticed that the light on my power brick was blinking erratically and from there (and perhaps predictably) the computer wouldn't turn back on. I've been looking into the possibility of the power adapter overloading (the one I have is 19V and 4.74A), so I ordered a new one (at 3A) in hopes that will correct the problem. Am I doing this right? And how can I prevent this from happening again?

I'm using an ASRock H510TM-ITX (thin mini-ITX) motherboard.

UPDATE: After doing some more research, I've come to the conclusion that 19V is too much for my motherboard... even though the manual recommended a DC power brick of that voltage. Well, I guess you can't make that stuff up. Fingers crossed everything is okay (and will be once my new power adapter gets here) and I won't make this mistake again!
