My computer is one that I put together myself so when it breaks I am the only person arround to fix it. The other night the computer turned off and the PSU started smoking. I hoped that all I needed to do was replace the PSU. Unfortunately it wasn't. When I switch on the PSU the lights on my case flicker on for a brief moment and then go right back off. The green light on my mobo is on but when I push the power button on my case nothing happens at all.
What all could be broken and need fixing?
