I recently upgrade my computer's power from 350 to 500, but now it refuses to remain powered on for more than a couple seconds. The first time it remained on for 5 minutes, long enough for me to get a game running, but then it shut off, and now when I power it on it makes a sad whirring hum, then turns back off.
I decided to have some help putting in the thing, since I'd never done it before, but I am skeptical of the individual's skill, as he went off a youtube video as he did the transfer. (Not that I have anything against tutorials, but if you're advertising as a computer hardware technician, it doesn't really help your credentials.)
So I'm wondering, is it the hardware installation that sounds like it's an issue, or would it be compatibility with the other parts? I don't have a lot of knowledge regarding hardware, so I'm just looking for some help regarding the identification of the issue. Thanks!
