Well, it IS working now, but earlier it wasn't. Last night I finished working and put my desktop computer on Hibernation. This morning I come in and turn it on, only to find out that for some reason, the computer freezes at the blue HP Invent screen, you know, the one with the Setup and Boot Managing and System Recovery options? I then call on my dad and we try to fix the problem. I noted that some of the peripherals that were hooked up to the computer (like a microSD to USB thing that I have that glows red when it works) started working before Windows actually started, because, of course, Windows wouldn't start up. The computer as said, just froze on the blue screen. So I disconnected some peripherals from my computer, turned it on, voila, works. I don't know why power supply would be the problem, because this is probably the only time something like that happened. However, what must I do to prevent further issues similar to this? What is the problem really?
