Hi, I am using dh61ww mainboard with graphic card and 1 slot of 4 GB ram.
Yesterday my PC can't boot up.
The fan of CPU and graphic card runs, then there are 2 long beeps, silence for about 2s then again 2 long beeps, that's all, the fans keep running but nothing else, no restart, no more beeps.
I pull out everything, graphic card, hdd, clean Ram, even the battery but no luck.
I am using latest bios update and it was working fine. This morning it suddenly boots successfully, works perfectly but it was the last time. No more luck today.
Sorry for my bad English.
Based on your description this can be a video issue. Two beeps coming from the board means a video error. Here you can check this:
I recommend you as first troubleshooting steps to disconnect the Video Graphics card you have and start the system with onboard graphics.
Here you have another link with more information:
Is there any possibility to test another processor on the motherboard?
If issue persists, after doing the step above, I recommend you contacting our phone support for a possible replacement:
