Computer shuts down on boot and claims Windows failed to start.?

I had something rattling around in my fan the other day and turned off my computer to shake it out. When I try to restart, if the computer manages to turn on, I get a windows failed to load because of hardware of software failure, it will then try and fix the problem till it turns itself off. Most of the time the computer will boot and turn off mid boot. The longer I have the computer off, the longer it will run thru an attempt at repair. If I turn it on immediately after turning off, it lasts only a handful of seconds before shutting down. No beep codes, no nothing. Any ideas?
