Can't reach the installer.

Hi, I cannot reach the installer on El Capitan, Apple logo appears for 5 seconds and the PC reboots.
When I try to do verbose mode, it restarts instantly.
cpus=1 doesn't help.

Intel Core 2 Quad Q9300 @2.5 GHz
AMD Radeon 1650 256 MB
MS - 7345 VER 1.2

Thanks and sorry if I am asking answered question.

Sorry, in verbose mode, it shows 15 white dots at the top left corner. Then it reboots.
