H520: Black screen after update - wont reboot

2016-06-16, 1:03 AM

After a recent update done on my Lenovo desktop, I ran into a problem.

 

My computer worked perfectly fine previously but after the update and a restart of my computer, a black screen showed on my moniter.

After reading up on a potential fix and unplugging/reattaching everything, the black screen remained.

 

I have tried restarting several times but the black screen remains even though everything is on and plugged in properly.

 

Anyone have any thoughts or advice on what I can do to fix this?

 

- The computer does not have onboard graphics.

- Nvidia Geforce

640 1024 DDR3

RAM

- Installed new 350 watt power supply to better run graphics card

- Has had a similar problem before but can not recall how I had fixed it.

 

Mod's Edit: Serial number removed from public view to protect owner from its unwanted use.

I need help, you see my laptop has stopped working. I turn it on and the lock screen comes up as usual and after I enter my password the screen is just blue. Do you know how I can fix this ?

I also have this problem.

 

H520 Desktop. Windows 8.1

 

I can never just reboot.  I must always to a complete shut down and power up or it will freeze. I could not update to Windows 10 because it does automatic reboots and it messed up the upgrade.

 

Any help would be greatly appreciated.
