Sammy Soto, try this firs. Disconnect all power sources, battery, plug, usb devices, then hold down the power button for a minute to clear residual charge. this should reset your bios. If it does start up go to the diagnostic tab and run the hard-drive and memory Tests. See what it shows. This could be as simple as a bad memory module to as bad as a failed CPU.
