That SearchIndexer may be a suitable suspect.

Good work on your use of the Task Manager. It is not always an easy concept to grasp for many users.
svchost.exe is a known process and multiple entries are common in Windows, so there is no problem with those. There are viruses and other malware that attempt to disguise themselves as svchost.exe processes, but at this stage I do not believe this is a problem with your system. Normal anti-virus utilities can identify these threats, so unless we are unable to solve this issue with my suggestion below, we can safely ignore those.
Similarly dwm.exe is a known process and we can ignore that.
taskmgr.exe is, of course, your Task Manager when open.
So that leaves us with SearchIndexer.exe. This is related to the WindowsSearch Service which "Indexes" all of the files on the hard drive to facilitate search and other things. More information about it in the link below;
On a new system this can take up a lot of CPU time as it catalogs all files and contents. It does this in CPU idle times, eg whenever you are not doing anything, but I can imagine on a multi-core system that it can kick in at any time. After a while (days to weeks or more), it's work is done, and so it only scans for changes.
This is a service that can be disabled without any effect, as long as you don't intend to use it to search for content in file documents, emails, etc. Also, the normal Search function in the Start Menu or any Windows Explorer window is not affected.
So, if you want to disable this service and see if that works, try this;
1] In the Start Menu, if you do not already have the Run command shortcut, use Search to search for Run. Open the top entry listed and a new window will display. If you already have a Run shortcut in your Start Menu, click that.
2] Type in services.msc and click OK, (for clarity, that is SERVICES.MSC).
3] In the new window, scroll down and search for Windows Search. Highlight the entry and double click it, and the Windows Search Properties window will open.
4] In that window, click the Stop button. When the service has stopped, use the pull-down menu for "Startup type:" to select Disabled. Then click Apply/OK.
That should stop the service and prevent it from starting each time you boot up.
See if that reduces or stops the cursor flashing. If not, you can always restart the service and we look elsewhere.
