Weird screen after waking up locked windows

[HellHound420]

Hey! I have an issue with my computer. If I lock it down with the windows key + L button and monitor goest to sleep..etc when I try to wake it up sometimes it gives a noisy static like image and sometimes I can only fix it with restarting with button or trying to gave it my passcode and log back in. I tought it was the GPU but I changed it and I still got this issue. Help me please! 

Sorry for my bad English. 

 

My pc's specs: 

CPU: Intel Core I5-3450 

RAM: 2X4GB Kingstone DDR3 1333MHz + 2x2GB Kingstone

GPU: Sapphire RX 480 Nitro+ 4GB GDDR5

SSD: Kingstone A400 240GB

OP: Windows 10 pro 64bit

quite sure it is not RAM related but maybe try using only one set of RAM?

 

have you checked if the problem is still present if you connect to another screen?  ( or turning the screen on and off )

 

if all of those don't help try reinstalling your graphics drivers and as a last resort the only other thing would be your mother bord I guess?

I did change the rams but the problem is still up, I dont have another screen unfortunately  but I did try to turn off and back on the monitor nothing changed. And I already reinstalled the graphics driver, changed the graphics card, and reinstalled windows.

oef that sucks indeed 

you don't have a tv you can plug it in? ( however I don't think it is the screen f turning it on and off doesn't help you)

 

the Intel Core I5-3450  has onboard graphics if I m not mistaken right? 

try sticking the HDMI to your motherboard instead of your graphics card

I already tried that too, idk what else could I try

Okay so try this:

 

Pres window +X 

Go to device manager 

Expand Display adapters 
Right click the current display adapter 
Click Properties 
Click Driver tab 
Click Rollback driver if the option is available 

If not 
Right click the current display adapter 
Click Uninstall 
Check the box that says, "Delete the driver software for this device.” 
Exit Device Manager 
Restart 
Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.

 

I m pretty sure it is a driver issue, as a last alternative try getting the right drivers from website  of the manufacturer instead of the software
