No other symptoms?  No error messages?

I would start by re-seating the memory modules.
Then I would re-seat any expansion cards (video cards, etc).
Then I would re-seat all my power connections.
As a last ditch effort (and with no other symptoms present) I might re-seat the CPU.

About the only reason it would do this is if the BIOS is damaged. Can you re-flash the BIOS from a CD or USB Key?

If the system won't go into the BIOS, there is a hardware issue.  Since you've removed nearly everything from the system, the possibilities remaining that the issue is fixable are narrowing down.

You can try:

  • Extract memory to a minimal configuration, then shuffle modules to see if it's bad memory
  • Per paulmacd's comment above, reseat everything
  • Detach the few remaining things you haven't already - keyboard, mouse, add-in display adapter if it has one - and see if it boots to BIOS
  • Buy an inexpensive PCI POST card, and see where the system is hanging in the Power On Self Test

When it gets to the point where a POST card is necessary to diagnose a BIOS POST failure, this often means the problem is hardware failure on the motherboard.  Unfortunately nothing fixes that except a new motherboard.  A POST card just confirms it.

Can you contact the manufacturer's support desk and ask what you should do. It could be motherboard in addition to BIOS.

If BIOS and Motherboard were OK and the hard drive was dead, you would get different messages.

If you strip down the system to most basic components and then re-seat those components like CPU and memory, you may come to know the issue. You just need the mobo, cpu, mem, display and keyboard, I suppose some interrupt requests are messing up.
