Try Unplug it, remove the battery, press and hold the power button for 10 to 20 seconds. Replace battery and try it.

Do you know how the memory is configured? If there are 2 modules and you can easily reach them. Try starting the computer with only 1 in. If it starts, turn it off and try it with the other. If still working, try both again. Could be a module failed. If it will start with 1 of the modules but not the other, then you'll know which failed.

What model of toshiba is it? Model number should be on a sticker on the bottom somewhere.

You tried all you could without replacing the motheboard, that is the next step and from what is happening is likely the issue. For a 3-4 year old model likely not in warranty, unless you can do the work of replacing the motherboard yourself it's likely not worth fixing, replacing may be beter.
