Most likely cause is the power supply, if it really wont turn on, if it comes on but doesnt start, the you have a computer problem. Check and see if the fans work when you push the power button or if any lites come on, then the power supply is most likely OK. If the computor does actually come on, but does not start, see how may beeps it makes. then repost your question with that info.

My Dell T3500 will not install the two extra hard drives i have installed


Go to the BIOS settings and make sure the drives are recognized by the BIOS. Ensure they are set as either Master or Slave drives depending on where they are fitted.
Your OS should, once the BIOS picks them up, format as required.
