PC screen not turning on

[eddiebar2000]

I recently added a m.2 slot SSD to my motherboard and moved the old which was pcie3 to the slower slot. When I turned the PC on the screen came on and I saw the new SSD in task manager but not on the file manager. Then I reset the PC and the screen would not turn on. I tried putting the old SSD back into the original slot and reseating the GPU as I had to move that but the screen will not turn on

What's happening with your display?  Is it showing a black screen, is backlit, and does not have the "No Signal" indicator from the OSD?  I recently dealt with something similar, where I had to go into safe mode, uninstall my graphics driver with DDU and reinstall it clean in order to get a display.  If you have an Nvidia card and recently updated your graphics driver, that may have been the culprit.

 

To the original issue with the SSD, it won't show up in file manager until you initialize it (give it a partition and format it) through Disk Management.  Make sure that the drive you initialize has no partition and its available space is slightly smaller than the advertised capacity of the SSD, otherwise you'll lose data.

 

Oh, to enter safe mode without being able to get into Windows proper, just start the machine and force power it off with the power switch on the case (not the power supply) three times.  Then Windows will give you a recovery environment.  Go into Advanced Settings, and look for the option to pick a different startup behavior.  Choose safe mode with networking so you can download DDU and a fresh copy of your graphics driver.  Run DDU, select options relevant to your card on the "first run" screen, and then remove the driver.  You may be asked to restart, or the machine may restart itself.  You should get a display at this point.  Install the driver you downloaded during the safe mode session, and choose the option to do a clean install, just to be sure that everything goes on fresh.

Same thing happened to me.  My mouse had RGB, but my keyboard didn't.  Again, your display doesn't show "No Signal" right?  Also, try moving your mouse cursor.  If one shows up and it displays the "busy" state (animated blue circle), then your issue is the graphics driver.  Do the process I mentioned.  It'll get you back up and running.  Something broke with the latest Nvidia driver for me.  It needed to be installed clean to be happy.  Just running a clean install from the Nvidia driver didn't work.  I had to rip everything out with DDU and start over.

When I plug my screens into the GPU the lights on the screen turn blue momentarily . But when I turn the PC on the screens stay on standby mode. I tried putting it in safe mode but nothing changed

Do you have another machine you could test installing your GPU in?  You mentioned you reseated the GPU, did you also reseat the PCIe cable(s) at both the power supply and the GPU?  Does your GPU have a BIOS switch?

Got it to boot in safe mode. It's now working. Formatted the drive, it now shows up properly
