A 3-beep error code is usually related to system memory. I'd recommend checking that your modules are well seated, and confirming that they are fully compatible with the motherboard. Also, check them one by one to find out if any of them is defective.
I have understood all, thanks for a response.But my problem is deeper.All components serviceable and compatible with each other.But PC doesn't start.Me have suggested to update bios. But I can't do it becouse PC don't run. I need another CPU to run PC and updating bios.Maybe it's single possible exit to me.
The processor and the motherboard you have are both fully compatible with each other, without the need of a BIOS update.
Please let us know how exactly did you test all components? Did you test the motherboard with a different processor and RAM?
Since you are getting a 3 beeps, I would still recommend looking into the memory as the possible cause. Testing different modules, from a different manufacturer is a great place to begin troubleshooting.
The CPU and memory worked on P5G41T-M LX (Asus). The motherboard started with M378B2873DZ1-CH9 (1Gb Sansung 1333Mhz) and CPU E5700. The memory Kingston ValueRAM <KVR1333D3N9/2G> DDR-III DIMM 2Gb <PC3-10600> CL9 also, does not work on dg41tx.I am afraid that I don't have possibility to test on it a lath of memory from each manufacturer. Can there are any parameters of conformity about which isn't written in documentation. Then it would become easier to buy the necessary memory.
I found a solution. This MB working with doublesided lath of memory.Thanks for Intel support and Jose_Intel. They have directed me in the necessary direction.
If 2 system memory brands have failed, then we can assume that the RAM ports on the motherboard are bad.
If you wish to troubleshoot this problem and eventually replace your board, please feel free to contact our support department:
