Answers :

Your motherboard is failing.
\015\012It is time to get a new PC.
\015\012You can try to find another motherboard to put into your case, but why would you want to do that? Unless you know for certain that the RAM, hard drive, video card etc are all good.
You have to ask yourself these questions.
\015\012The boot sequence is as follows.
\015\012First check the power supply. The fans to the power supply should start to spin. If you are getting power, check the power supply to see that it meets +12.0 V, -12.0 V, +5 V, -5 V, and +/- 3.3 V.
\015\012You will need a hard drive to trip the power supply.
\015\012Next, the CPU needs to start up.
\015\012Then the RAM
\015\012The the BIOS loads and checks the main circuits.
\015\012After that, then the boot loader is searched for, usually from a hard drive.
