Computer kernel data inpage BSOD

[Eviotie]

So randomly I got a BSOD and it was stuck at 100%. I gave it 2 hours same thing so i held the power button and shuted it off that way. Then I  tried booting it took maybe 30 mins to boot. ( Normally it would take 1-3) When I typed my password another 30 mins. When I tried to open up chrome I got a BSOD again... then i  tried it 2 more times and on the 4th time it worked and then got a BSOD. I tried it with other software and i kept getting BSODS. I tried AT LEAST 20 times over a 2 days. So I was like let me try a different windows user and everything went back to normal even the boot time. Mabey a week later i went to the other account to see if it magicy fixed it self and no it has not. Luckily I did a backup on MOST of my files the day before this happened but i still have some important info. Any help?
