I have an Emachine T2682. I turned it on one day and it wasn’t recognizing my monitor (46in flat screen tv). This was unusual because it has worked on this tv for about 8 months with no issue. So I tried to power down the computer by holding the power button. It would not turn off but it was running loud, I had to unplug it to turn it off. I gave it a couple hours and tried again. This time it made a sound (like a circuit going) and a small puff of white smoke came out of the back of the machine. The green light on the power button was still on so I quickly unplugged it and haven’t touched it. Does this sound like a power supply issue or did I fry my motherboard? I would like to save this computer if possible. **I upgraded to an Nvidia Geforce video card and added ! GB of RAM.
