Hi Yugtob,
Seems like you're having problem with the
display of your computer. There are some reasons why your system displays
shaky and
cloudy screen. Sometimes it caused by a
corrupted video driver or system has a
faulty screen (hardware failure). Going to the
bios and installing the
latest driver are basic diagnostics that you can apply to check if this is a software or hardware problem.
Try to replicate the issue by going to the bios1.
Turn off the computer.
2.
Boot the computer then start tapping the
F2 key.
3. Inside the
bios please observe the display if it's still
shaky or
cloudy.
-->
If it has the same issue, system has a faulty screen and needs to
be fixed and
replaced.
-->
If no issue, just reinstall the
video driver.
How to reinstall the video driver.1. Download the driver
here:
2. Go to the
video section. Then select the
operating system that corresponds to your computer.
3. Save the
.exe file to your desktop.
4. Install the driver then
restart the computer.
--> if you're still encountering the same issue try to perform
OKR to set the computer back to the default factoring setting.

One Key Recovery (
OKR).
