I vave already replaced this motherboard

PC generates three long beeps (1 Second Cycle three times then 2.5 Secondds Pause) when there is Memory (RAM) Error. Try inserting DIMMs again. Make sure that the timings (Clock Speed) of DIMMs are compatible (matches) with your motherboard.

do you feel that hot air is coming out from it? if so you should look up for any beep or sound that comes as a code.
1. three beep sound for ram
2. one short two long or two short one long for vga card
try to clean and replace your ram, or graphics card if it in not build in.

Hi.first pull-out your motherboard in the CPU case then power on without memory only processor installed.if you hear continuous beeping your motherboard is working good.
try this beep code means.

No beep means short,no power,bad CPU,loose peripherals.
One beep means everything is normal running motherboard.
Two beep means CMOS error IC.
One long beep,one short beep means motherboard problem.
One long beep,two short beeps means video card problem.
Three long beeps means keyboard error.
Repeated long beeps means memory error.
Continuous hi-lo beeps means CPU overheating.

Hope can help you.

hi, try replacing the battery of the motherboard for it may be worn, a faulty battery usually makes the board not to work or sluggish. hope this helps

replace the ram

Need to know the specific number of beeps to analyze this but all computers need three things to fire. Ram memory, CPU and video. Those are the root of most beep codes. Check your ram memory sticks and make sure they're fully inserted in motherboard. Make sure the video card is inserted properly if it's not an onboard video. If it's not one of these then you probably need to find a professional and it's a pretty good chance the motherboard may be bad.

sometimes using an eraser over the metallic part of the RAM stick can get it to be read to the system..i have tried it many times it works

First replace its CMOS battery.

Although the memory may be working okay in another system, the three beeps at post still indicates a memory(RAM) problem. Your motherboard uses AMI BIOS, as indicated by the product specifications on the Asrock website; In the post-error code listing, three beeps is a memory issue.

Check and make sure you have compatible memory for the motherboard; and if possible, test with new or alternate memory sticks.

If new memory doesn't resolve the issue, I would say the RAM slot(s) is damaged, which would require totally replacing the motherboard.

Hope this helps!
