PC won't boot (Asus P5K pro mainboard) No beeps, no screen output

Solution 1:

1. Easiest way to solve this problem – get a new PC.
2. Not-so-easy way to solve this problem – upgrade CPU, motherboard, PSU, RAM

3. Hard way: isolate which part is causing the problem, then replace it

   • test PSU
   • check CPU
   • swap RAM
   • test motherboard

Solution 2:

If your computer does not produce any beeps while attempting to boot with no memory or graphics card (assuming it doesn't have built-in video), the motherboard needs to be replaced.

A large majority of motherboards will produce a string of beeps alerting the user to an issue if the system is powered on without RAM. Hence, if your computer makes no beeps, there are bigger issues - ergo replace motherboard.
