Windows does not start

[askat]

I have an asus desktop computer, i cannot get into the set up page to reset or put set up defaults, the pc keeps shuting off, and i can not get into BIOS what should I do?

Open the case. Check the cpu heatsink to be sure it's intact and making good contact with the cpu. If you haven't physically moved the pc lately, I would try a different power supply first. Then, if this doesn't work, you'll have to start disconnecting each device one at a time until you can get a bare bones post. Then you reverse; connecting each device back and trying to start up your system.
