I would recommend to disconnect all external devices and also internal cards and devices (hard drive, cd rom driver etc) just have your motherboard processor keyboard and power supply connectors and front pannel connectors press the power button and watch the keyboard, if it flashes the lights twice or once. if once turn off the power and then remove your ram modules and turn on check if you get beeps from the motherboard buzzers, if not its is evident that the motherboard or processor is definitely bad. you need to check and replace them.
some times even a bad power supply with less supply of voltage cause this if you have another power supply (SMPS) unit check with it.

Unfortunately the GPU on your motherboard has gone out. There are places that will fix it but it is best to replace the motherboard. The good news is that replacements are going for about $50.
