Problem operating computer-display signal

Recommended Posts



I assembled a computer with the following specifications with From a previous computer.

The first time I turned on the computer there was 1 long beep and 2 short beeps without a display.

After messing with the connections, somehow the matter worked out and there was a proper beep.

The problem right now is that in different situations, the display suddenly stops and restarts,

There are abnormal beeps, like the first time and again somehow after tinkering it works out.

I still have not found what exactly causes the computer to return to normal mode until next time.

 Could it be related to the power supply, which is too weak for the new specification?

if you have New and proper check with him it will be the best.


Maybe it's a memory problem that is not sitting well enough, take out the memory and insert again and make sure it fits well.

Do the same with all the power supply wires, which are all connected and you have connected all the electrical connections to the board and did not forget one by mistake, check with the guide of your board Page 13:


Make sure you have installed all the parts according to the instructions on the motherboard:
