PC problems/ No keyboard lights, no post, no bios, etc

[Diego_Ramirez]

Im in great need of help as one day I was playing when my PC suddenly turned off and it wouldn’t turn back on again, the PC would have power as the fans would work but they would go fast then slow down and repeat, so I tried all the usuals but nothing would work so now I got a new MB, RAM, and Power Supply but now my PC doesn’t have the fan issues anymore but it still won’t have power to the keyboard and mouse and still won’t put anything on the display so please any help would be great.

My specs for the PC:
Ryzen 5 1600
MSI B450M-A PRO MAX II
T-Force Vulcan Z DDR4 DRAM 16GB
Powercolor RTX 570
AGV Series 500W Power Suppl
1T Blue Western Harddrive
256 NVME SSD
NZXT Case

Help please.

What Graphics card do you have?

[Diego_Ramirez]

a Red Dragon Radeon RX 570

[PeterOz]

Sorry for all the questions but your spec list is basic.
How many sticks of ram 2 x 8 or 1 x16
also what speed.
Does cpu fan turn on

[Diego_Ramirez]

No, you’re good anything to fix my PC:
they are 2x8 with 3200 MHZ and I’ve tried switching slots and putting only one in and so forth
and yes the CPU, Case Fans, and GPU fans turn on and run well

[PeterOz]

Remove ram
Power on
any beeps or anything on screen?
If not
Power off
1 ram stick in slot B!1 - Closest to the power connector
Power on.
Is the keyboard connected to USB 2.0 Port Black connector?

[Diego_Ramirez]

no nothing is still the same issues after trying no sounds or display
and no the keyboard is connected to the blue USB but I did try all of the ports

[PeterOz]

Power Off
Put kb & mouse into black.
Is KB a wired KB or wireless?
Is CPU fan connected to cpu power socket - Pic attached.
Reset Cmos - Pic attached.
Disconnect 1 TB WD Drive.
Only have KB & Mouse connected.
Power on.

If no result.
Power off
Connect WD and remove NVME
Power on

[Diego_Ramirez]

Still no results from doing both i removed the CMOs for 5 mins everything powered off nothing the KB is wired and the Mouse is wireless but they work on other devices and the CPU fan is connected to CPU_FAN1. No Results still the same unfortunately

[PeterOz]

Did you disconnect Drive.

Disconnect 1 TB WD Drive.
Only have KB & Mouse connected.
Power on.

If no result.
Power off
Connect WD and remove NVME
Power on

[Diego_Ramirez]

Did all that was said in order I also clear the CMOS but same results and disconnected the drive. everything looks the same as the fans are fine but no power to KBM or any display I even tried another monitor and HDMI and Display port

[PeterOz]

The only other option I can think of is that your BIOS does not support the CPU
and the bios needs an upgrade.
Can you see the revision number on your MB

[Diego_Ramirez]

i’lI find the revision number right now but I did find a new issue as after I booted up the PC after CMOS restart the GPU fans started going from slow to fast

[PeterOz]

Power off
Press on button a couple of times to remove all charge
Remove GPU
Reseat GPU
Power on.
