I had my computer shut off all night and plugged into a surge protector. The power went out a few times over the night. First its an Emachines T2615, AMD processor, Nvidia Graphics card, windows XP and when i woke up the power light on the front of it was on, but the computer was not on. Also all 3 lights on the keyboard were light up and flashing. Neither of those are normal. I tried turing it on and the monitor just said check signal monitor is ok. I tried unplugging it, using different plugs, everything. The computer sounds like it starts up fine but nothing happens. I tried it without the nvidia card, using the built in one and same deal. I took out the hard drive and tried to boot, same thing. No BIOS or anything. Any idea what this could be? I need help asap. Thanks a lot.
