Hello,

I've purchased a MSI FM2-A75IA-E53 and a Richland A4-4000. Since it won't boot at all, I read that the mainboard requires a BIOS update, and in order to do this, it requires also a Trinity APU. So, I bought a Trinity A4-5300 but it won't POST either. Then, I tried to remove the battery, clear CMOS and switched on => I could hear a long beep followed by 2 short beeps, and nothing else (black screen). I also noticed a surprising thing: I turned off then turned on again => no more beep, nothing. But if I removed battery.reset CMOS, then I could hear the long beep+2 short beeps. Once. Each time it would beep once, and only once, until I remove battery/clear CMOS again.
Do you have any idea about what it could be? Normally 1 long beep+2short beep = bad display adapter, but well, my APU does have a IGP and must be able to display something right? I tested both onboard VGA and HDMI output, both unsuccessfully.
Thanks in advance for your help. Regards.
 
Indeed, I tried several things:
- removed all the RAM => 3 short beeps. I guess that was the error code for RAM missing
- used a friend's working 4GB DDR3 1333Mhz => still 1 long beep, 2 short beeps
Maybe I'll try to put a discrete video card but I'm really not optimistic about this solving the problem..
 


Well, it's good idea to put discrete video card. At least you'll have more info.
 
Well, I put in the working video card from my main PC and, still the same... 1 long beep, 2 short beeps. This is driving me nuts. What could it be? Maybe should I try other DDR3? like 1600 instead of 1333Mhz? I really don't know what to do 🙁
I don't think the CPU is defect, so, only remain either the mobo, or the RAM... Beside, I really don't know what this beep code means, nor why it only does that once after clearing CMOS
