Black screen no boot no access to the keyboard

[SavageWarrior]

Hi Everyone,

my computer starts up but will not boot. II'e tried the bios reset, removed memory cards and hard drive per troubleshooting and still nothing but a fan running.

I can't do a hard rest or access the bios because the keyboard is look like is not working, I tried to use an old one and no success is not working .

This may be a start.  If it is making any beeps or flashing any leds it may identify the problem.

Is the fan spinning and is is spinning fast?

Does it have internal power supply or external? Is the keyboard wireless or usb?
