Freezing Leading to Scrambled Screen/Questionmark Folder
(So the mac has frozen two times while attempting to write this message - on the phone now - hopefully this freezing bug is not contagious :D)
My mac has started to freeze since the last 3/4 days. After the cursor freezes, 50 percent of the time with the rainbow scroll, I close the lid of the laptop and the screen light turns off(I can see from the logo). When I immediately reopen, either a scrambled screen comes, or the laptop seems to restart. When this happens it goes to a flashing question mark folder most of the time or a white screen. I then force restart with the power button and laptop boots up as usual. The first times it seemed to happen when the mac i felt was under load, e.g first time was when football manager was open with a number of safari tabs as well. It also happened when I was scrolling reddit, when i sometimes get a safari notification saying reddit is taking siginificant memory.
However this issue has migrated to instances when there is no load. In the past hour the mac has had this issue 2 times, when the only thing running was safari and the ifixit tab. (Although i had attempted to write these messages straight after rebooting from a crash).
Also in the last crash, i got a message before logging onto computer of a “the system is unable to unlock your login keychain - login keychain is damaged, cannot be used, new one created. Does this suggest an access to memory problems, as I also get the flashing question mark folder occasionally?
Does what I am observing seem to match a common symptom, and if so, is there a potential fix?
Many thanks in advance…
