Ubuntu 21.04 freezes in dell inspiron 15-3000

eg flag

I am experiencing random screen freezes too often while working on ubuntu 21.04 in dell Inspiron 15-3000. The system came with a Windows 10 OS, and I dual boot it myself and is currently having Ubuntu alongwith Windows OS. Windows work pretty well. But ubuntu freezes quite often, like 6-7 times in 1 hour. The mouse, touchpad, or keyboard doesnt work and i have to reboot the system using the power button.

Sometimes, it may restart itself after a freeze. I am new to ubuntu, please help me solve the issue.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
