Hi Saurav,

Thank you for posting your query on Microsoft Community. We are sorry for the inconvenience caused.

I see that you are facing black screen issues with the system. This might be due to the corruption of display driver in the system.

I would also suggest you to refer the article in the link below on

I also see that your system has become slow hence I would suggest you to follow the below methods and check if it helps,

Method 1: System Maintenance troubleshooter

Please follow the steps to run System Maintenance troubleshooter on the computer:

• Type “Control Panel” on the search box.
• Click on Troubleshooting.
• Click on View all option on the left side of the Windows.
• Click on System Maintenance option.
• Click on Next and follow the onscreen instructions to troubleshoot the issue.

Method 2: Disk Clean Up

Cleaning out your PC on a regular basis frees up drive space and helps it run better. One of the easiest ways to clean up files you no longer need is by using Disk Cleanup. Try performing it on the system and check if it helps to
resolve the issue.

Refer the below link to perform a Disk Clean Up on Windows 10.

I would also suggest you to perform a clean boot to check if third party applications are causing the system slow.

Method 3: Clean boot

Place your computer in clean boot state and check if it helps.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

Gtx 460 black screen issue

I have an EVGA gtx 460 that has started acting odd. Every once in awhile I would get a black screen that would require a hard reset. Then eventually the other day, it wouldn't boot at all. It would boot to the windows logo and then black screen.

Replaced it with a spare card, booted up fine.

Put the 460 back in, black screen.

Booted in safe mode, boots fine.

Uninstalled driver and reboot to full windows... boots fine with no driver installed.

Reinstalled latest driver (was already on latest driver when this started) and rebooted. Black screen.

Booted into safe mode and uninstalled driver again.

Reboot to full windows, install old version of driver, reboot. Black screen.

Reboot to safe mode, uninstall driver, reboot to full windows install reeeeeaaally old version of driver. Reboot. Black screen....


So... the only time the card works is when there is no nvidia driver installed... weird.


Anybody got any ideas? I haven't tried testing it in a clean windows install yet, but that's my next step I guess.
