Unable to POST with motherboard MSI x470 gaming plus

[klebermo]

This setup was working fine for a few days, until I made a change on the memory (could be a coincidence, though. maybe I mess something else while changing the ram?). Now, when I try turn the machine on, I got neither an image on my display or any bips. Everyting else seems to be working (indicator leds on motherboard all light up, all fans start spinning, video card included). I checker the ez debug indicator leds, and each one of them turn on and off after the respective check, except the last one (from the top to the bottom), which, if I am reading it correctly, would indicate that "the booting device is not detected or fail" according to the documentation. Anyone already had a similar issue with this board? ANy tips of how to fix it, If it's possible?

 

besides the MSI x470 gaming plus board, I have a processor Ryzen 7 1700, 2x Kingston HyperX Fury DDR4 8Gb, a M.2 SSD with 240 Gb (it was working on M2_2, but I've tried on both slots), a 2 Tb HD on SATA 4 and a Radeon  RX 550 video card (XFX). I tried a Clear CMOS, but this not fix the problem.

Could be a drive failure. Try taking out the SSD, and see if you can get into BIOS then.

Tried that, but even with no drive conected, nothing happens ( I tried only with the HD connected too).

Update; I tried connected only the HD (no SSD) and after some reboots, I got a message on screen (just telling no boot drive was found - OS is installed on the SSD). After that, installing the ssd again, all the LEDs in the ez-debug stay off, but the display stays with no image.

But you still can't get into BIOS, even with just the HDD connected?

I enter the BIOS, and after several reboots and clear cmos, I now can boot the pc, and manage to use windows for a few minutes, until the pc start to get very slow and crashes.
