Question mark sign on folder appears while powering on.
Macbook pro early 2015 13 inch (16gb ram 256 ssd aftermarket) I am using bigsur in it.
Whenever i powers on my machine QUESTION MARK SIGN ON FOLDER starts blinking.
Sometimes it appears and sometimes it doesn't. Totally unpredictable.
I have done following things as solutions but sign comes again after somedays.
Reset SMC and NVRAM, Disk Utility Repair, Factory reset machine, Reinstalled new OS from bootable drive.
Still question mark sign appears after working fine for few days. Really tired and irritated from this issue.
Need your help guys, what could be the problem?

If you can get your system to boot up, one more time let's check the System Preferences > Startup Disk setting. Make sure you've got your internal drive selected. Unlock the setting and re-select the drive (macOS version)

@danj Already done that.
System immediately boots up after clearing SMC or resetting NVRAM.
But on every startup sign appears after some days. Then after some days it vanishes automatically. Then comes again out of no were.
