Computer shuts down few minutes after startup.

This started a few days ago and initially I pulled out two sticks of RAM when initially it would boot up and not bring up any signal on the monitor. Now it boots up but when I start a game or plug in my external drive it shuts down after only a few minutes.
The computer stays on when I use it for movie watching. Any ideas?

 

Desktop blinks a few minutes after startup, then printer disappears

I installed Windows 10 version 1903 on 9/13/2019. Since then, I have experienced the following behavior. Within five or so minutes of system startup, the screen goes black for a couple of seconds, then the desktop reappears. This always happens twice in a row, a few seconds apart. Never more than twice, and never less. I thought nothing of it until today.

I have an Epson USB printer which I used today for the first time since 9/13/2019. Normally, the printer icon shows in the notification area, regardless of whether the printer is on or off. But today, I noticed that the icon was missing from the notification area. After restarting the PC, the icon reappeared, and I was able to make a print. But then the screen blinked, and after the desktop reappeared, the printer icon had disappeared!

If I go to Printers & Scanners and try to access the printer properties, I get this error:




But even worse, if I try to access Device Manager, I get a similar error:




I tried disabling Malwarebytes and restarting (as suggested in a post somewhere), but it had no effect.

 

Windows 7 low on memory during 20 minutes after startup!

Since a few months I have suddely a problem with my Windows 7 desktop:

During the first 15-20 minutes after startup it is having all kinds of low memeory problems:

• error messages "Your computer is low on memory. Close programs....
• browser windows crashing
• applications closing themselves down

After these 1-20 minutes, the problem disappears.

Any idea what is going wrong?
