Unfortunately, the POST beep speaker option in the UEFI/BIOS is set to Disabled by default. You won't get any POST beeps until that option is enabled.
When you say the CPU cooler fan runs for a few seconds, and then the PC "reboots", you mean the PC shuts off, and then tries to start again, correct?
What is the full model number of your memory?
Since you said you haven't built a PC in a while, I'll ask this. Is the the 4/8 pin CPU power cable from the PSU connected to the board? The connector at the top, left side of the board? That cable must be connected or the CPU won't get power.
When using 8GB or larger DIMMs, use the A1 and B1 memory slots first.
To keep things simple at this point, remove the video card and just use the integrated graphics.
After removing the video card, and possibly moving your memory to the A1 and B1 slots, be sure to clear the UEFI/BIOS with the Clear CMOS jumper on the board. Do that with AC power unplugged and the PSU off. Do NOT skip this step.
No idea if the PC case being used is new or old. Any chance the mother board standoffs for your previous board are in different locations than the new boards, and one is shorting the new board?
Not having any spare parts to try will make things more difficult.

The connected PC speaker dont beep @all (tryd different speaker types!) Case 1: GPU Onboard (PCIe card removed): There is no Signal on HDMI or DVI - never (reboot after 3 seconds) *It dont matter if i Plug in one two or none RAM or SSD anywhere - all variants tryed - change nothing on the problem. Case 2: a. GPU PCIe: There is no Signal on HDMI, DVI or VGA - never but the MOBO dont reboot, the CPU and PS Fans are running. *It dont matter if i Plug in one two or none RAM or SSD anywhere - all variants tryed - change nothing on the problem. I also have removed the CPU and checked the contacts of the socket, they seems to be ok. Since this is a new platform for me, i dont have spare parts to check alternative parts (like ram..) ... my last cpu/platform change was with the Intel Q9450 -mike |
