Hi! I just made a
According to the Asrock site, the CPU you chose should work in your board. You are going to have to check the jumper settings, (see the manual page 11) jumpers J1,J2,J3,J4,J5,J6,J8,J9,J10,J11,J12,J13,J18,J21 only. You indicated that you also changed J7,J14,J15,J16,J17,J19,and J20 since your statement was "i looked at the manual and changed the jumper settings from J1-J21"
Also make sure you do not have a jumper block on the CLR CMOS down near the battery. If you left a jumper on, it will not boot
Also, make sure you installed the CPU correctly and did not accidentally bend a pin on the underside. see 2.2 on page 12 Installing the 775.
