I have recently built a new computer and when I connected all my parts to the motherboard which is a Asus Z87-Pro IV. When connecting everything and turning it on, there was a burning smell and a little bit of smoke. I quickly turned it off, waited an hour and turned it on again. There was no more burning, but my pc will now be on for 5 minutes or so, turn off, then reboot and be on all day. There also is no video input on my tv after trying an hdmi chord plugged into my motherboard, the I tried it on my video card. Then I used a DVI-HDMI chord and tried to plug it into my motherboard first, then into my video card. Both didn't work. I don't know what to do!
