Try disconnecting the video cable and connecting it again. Turn on. If that fails, you need to try other fix.
Ok, this fix requires to open the thing. Once open:
1) Remove ONE memory stick. Turn on. If nothing, replace the other memory sick and replace the ONE previously removed. Nothing yet?
2) Check if the processor fan is running. If so, remove the processor from its slot and clean the grids of the heat sink and fan, replace the processor and heat sink and turn the PC on.
