Try resetting CMOS or replacing the CMOS battery.

Disconnect the power cord. After you vacuum out the dust, leave the case cover off. Connect the power cord and power up your machine. Make sure the CPU and system fans are both working as well as the power supply fan. If the power supply fan and/or system fan are not working, the problem is most likely the power supply.
If the fans are working, it is possible that the CPU over-heated and may have failed because of all the dust. If there is accumulation of dust on the CPU heat sink, it blocks the hot air from the CPU from escaping. I hope this is not the problem!
Good luck!

Could be a bad power supply or the HDD is not working properly. Once you have the monitor hooked up, try it again and see if you get anything on the screen. If you don't then chances are the power supply is bad or does not have enough power to run the PC.
