Hi, I'm Sandy and I look forward to help you today.
I'm sorry about the issue.
Please follow the steps given below:
Hold down Windows(flag) key and then press letter R.
Type devmgmt.msc and click OK.
Device Manager window will appear on the screen.
Click Display Adapter.
Right click the items given under choose Update Driver Software.
And then choose the option "search it online automatically".
Some hidden malware/spyware/adware could be causing this issue:
I suggest you to scan your computer using free version of Super anti-spyware software. This will remove all of the malwares, spywares and viruses from the computer.
Note: If you already have installed Anti-virus programs like Norton, mcafee, CA, kaspersky on the computer, still I suggest you to download and install Super anti-spyware as the Anti-virus program does not remove Malwares/adwares/spywares effectively.
You can download the free version using the link given below:
Please run quick scan to complete the scan in 10-15 minutes.
If you have other queries regarding this, please reply back to me the box given below.
And if you can take a second to rate my service(click stars at the top of the screen and click Submit), that would be greatly appreciated. You can continue working with me even after rating.
