    Since you say the machine tries to boot, I'll assume the front panel connectors are correctly connected.

    • Make sure all cards, memory, and cables are properly seated. Including the 4pin/8pin motherboard power connector.
    • Try a different PSU. I had a PSU go out that acted this way, after an instant shutdown. Yours could be a DOA that acts the same way.
    • Try a single RAM module at a time. Switch modules if the first one doesn't help.
    • Try with all unnecessary components disconnected. Any damaged component can keep the PSU from receiving power good status.
