In your users' manual you will find a jumper switch on the motherboard that you move from one side to the other, and that clears the CMOS entirely. I know you removed the battery already, but I have to cover all the bases.
>First, establish if your computer is still under warranty or not. A low-level failure can be caused by only one of four things: a failed CPU, a failed Motherboard, a corrupted or failed BIOS (extremely rare), or a failed Power Supply. That indicates a low-level hardware failure. Computers will not boot unless a keyboard is plugged in. At this point, the boot signal from the power supply is not even reaching the BIOS the "beep" that you usually hear indicates keyboard recognition and that comes from the BIOS long before the hard drive is recognized. However, the fans spin up and I assume that the power-on light on the motherboard ("mobo") is on (if your board has one-some don't). I assume from your quote that there used to be a system beep when booting (correct me if I am wrong), and now there is none.
I assume that the monitor is dark and unresponsive. There is no single program that tests the complete motherboard. The only way to arrive at a conclusion is by testing the involved components 1X1 via process of elimination. There is no recent history of viruses or any application or other downloads or any external/internal component additions recently.

I have Norton 360 which runs every 3 days because of the kids using it while I travel and I run Windows Defender once monthly. This computer has given us no problems other than being Win 8 OS.lol. I have also pulled and reset the RAM and removed and replaced the BIOS battery. The monitor is a lenovo so its not the monitor screen. The HP logo comes up instantly as the computer is powered up but that is the extent of the startup. The keybords work when attached to a laptop. I also tried a wireless keyboard in all USB ports with no effect either. I tried start up with the F2, F8 F12, delete and esc keys pressed independtly and together, anyway, with no effect. The wired keyboard does not seem to have power as no key lock lights illuminate. The computer powers up and the hard drive spins for about 1 second with the yellow hard drive light illuminated then fading. Last Wednesday, a black screen with blue HP logo was as far as it would get during startup. My 12-yr old son reported that computer would not start while I was traveling last week. Anything I can do at home to tell which component is bad? Does it sound like the motherboard? How can I test it?
