Power supply is failing.
I am using a DELL Optiplex 9010 all-in-one machine for a long time with Ubuntu without having any issues. After having some updates, I did not restart the machine for 3-4 days. When I finally restart the machine the display starts shaking. I thought it may be an update issue. So I did update again (a few days later) with sudo apt-get update and sudo apt-get upgrade. Restarted the machine. But the problem is still there. Here I am attaching some pictures of the display taken by mobile phone.       [IMAGE]Shaking 3. Finally os loaded and continue shaking, please see the date and time at the top: [IMAGE]OS loaded How can I fix it? Any help would be appreciated. Thank you.
