Problem description: My machine no longer loads up after I tried to install some new RAM from 8GB to 16GB, I get 3 bleeps (1 long, 2 short) repeating . I bought my PC 3 years and 9 months ago, never had any major issues. Attempted fixes: Earlier this week I discussed with a colleague and we checked the RAM on a compatibility site for the mobo, I think he said the make and Mhz were the most important factors. I want to use the old and new RAM for 16GB to help with my video editing. Purchased it over ebuyer. Connected new RAM on Saturday morning, bleeping happened (1 long, 2 short = RAM issue). Now the mobo is doing this regardless of it being connected in variations with the new RAM, only old RAM and no RAM at all. I've noticed the voltage is different (1.5v on new, 1.65v on old) but nothing appears damaged. I've tried the following and powered on: 1. Removed the new RAM 2. Removed the old RAM (booting up with no RAM) 3. Air sprayed the slots 4. Removed my graphics card 5. Removed the mobo battery for 15 minutes to reset the CMOS The three beeps keep going and I get no AV output at all, so I can't check the BIOS. After some initial googling I tried: 6. Clear RTC RAM (Put jumper to slots 2-3 for 10 seconds while powered off, moved back to 1-2 7. Removed sound card (!) 8. Reseated RAM again, firmly pushing it in 9. Tried one stick of old RAM on its own 10. Removed heat sink over the GPU, checked it, seems fine, reseated it. I'm not sure what else to try beyond: 1. Buy new, less powerful but compatible RAM and see what it's like. 2. Rebuild current system, part by part. 3. New mobo, rebuild system The only explanation I can imagine is that I wasn't earthed enough so I've somehow damaged the RAM slots or motherboard, or the mobo is very sensitive (Perhaps due to overclocking from the original set up?). A replacement mobo at £46 isn't the end of the world at least but I'm desperate to see if there's anything else I can try first.

' It should work with 1600MHz, but that's only if the board is running the latest BIOS and it is configured correctly. In theory, it should at least boot to the BIOS. In your case however, you might want to go with the 1333MHz to avoid any issues.

Turn the switch on the back of the power supply to OFF. On the lower right corner of the motherboard is a jumper marked "CLRTC", move the jumper from positions 1 and 2 to 2 and 3. Wait about 10 seconds, and move the jumper back to positions 1 and 2. Power on the computer. 2. Try to plugging a system speaker to the 4-pin speaker connector (lower right corner) and monitor if any beeps that occur when you turn on the computer. 1 short beep = keyboard issue 1 long beep and 2 short beeps = memory issue 1 long beep and 3 short beeps = VGA issue 1 long beep and 4 short beeps = hardware component issue 3. Try reseating the CPU, memory, and video card. 4. Please make sure to check the power connections, specifically the 24-pin and 8-pin/4-pin. Have you tried using another power supply?'

I've tried everything I physically can with it, still getting the beeps. Going with a replacement motherboard, will swap components to it and see what that's like.
