recently my external hard drive was having problems booting up. It booted just fine except for occasionally it just didn't and I had to either switched off or switch and switch it on again or unplug it and plug it back in and then it would come whirring to life. then one day it just didn't. I thought that it might be the external hard drive enclosure power system so I took the hard drive out of the enclosure and put it into my tower. when I first booted up it worked just fineand I was able to get information off of it. Then suddenly It told me the hard drive is unavailable as if it wasn't powered on. So I did what I did when that happened on the external Drive. I unplugged it and plugged it back in. On the external drive all that did was cause the computer to forget it and discover it again. However I did not anticipate that unplugging it using the internal power source would cause any difficulties. What actually happened was there was a spark and the entire computer shut down. when I tried to boot it up again the power button is completely unresponsive. I even tried turning it off at the back, turning it back on, and try again and no luck. Even if I completely disconnect the hard drive I was working with and try again, no luck. Not even a splash screen, no beep, no fans, nothing. did I short the system out and by doing so foolishly managed to fry my motherboard? D: what do I do?
