Honestly and I am not normally the finger pointer type but I bet it is a Monitor Issue. May I ask why would you use vga over DVI? DVI is far superior in every possible way IMHO.
How I said, I have tried with two diferents monitor, so I discard that it is a monitor problem.
and I'm usin VGA connector cause its the only output my monitor has
someone else? any other suggestions?

Since you didn't mention that you have a separate GPU Card installed. I presumed you are using the APU Integrated Graphics.
First there is a very new BIOS/UEFI for your motherboard from Asus. Maybe updating the BIOS/UEFI might solve the problem. Also check to see if there are any settings in BIOS/UEFI that concerns sleep states. PRIME B350M-A Driver & Tools | Motherboards | ASUS USA

1.Update AGESA 1006
2.Improve compatibility and performance for Athlon™ with Radeon™ Vega Graphics Processors
Also there is November CHIPSET that includes VGA Driver you may want to install and see if it fixes the problem. PRIME B350M-A Driver & Tools | Motherboards | ASUS USA

- AMD Chipset Driver V126.96.36.199(18.10.20.02) for Windows Win10 64bit---(WHQL).
- AMD VGA Driver V24.20.11020.2003 for Windows Win10 64bit---(WHQL).
For troubleshooting purposes you can always purchase and "Active" HDMI-VGA or DVI-VGA Adapter and see if the problem still occurs.
As a work around you can always prevent your Monitor from going to sleep under Windows Power Plan.
thank you elstaci!! and pokester!! the reinstallation of the chipset driver solves the problem or so I think, even though I already had that version installed after installing the chipset and monitor driver again, everything became normal.
good to hear. You Chip set installation could have been corrupted when it was updated.
Cross you fingers it continues to keep working correctly.

forgive my confusion you actually said you used the dvi port in your first post and it worked. Good luck!
Most sleep issues even with different monitors go back to being lack of proper monitor drivers being loaded. With the monitors you have tried have you been loading the specific monitor driver for those monitors?
