Laptop booting issues

[cardsfanbj]

I have a Toshiba P855 laptop that had the fan bearing go bad in it, plus the thermal paste was old and I wanted to replace it. So I ordered the new fan and bought new paste, replaced the fan, and now it refuses to let me into my account. 

 

System will boot, get to the login screen, and when I try to enter my password, it crashes. The system reboots and at the Windows screen it wants to run a disk check and it will either fail and crash again, or it will fail and prompt you whether you want to continue, troubleshoot, or shut down. Loading now prompts you that "automatic repair couldn't repair your PC" and gives you the options to shut down or click on advanced options, which has continue to load windows 10, troubleshoot, or shut down.

 

The fact that it reaches the login screen confuses me, since it makes it seem like there's no hardware problem, but the drive shouldn't have any problems with it, and it booted just fine prior to replacing the fan. Boot drive is an SSD, so it shouldn't have had problems with anything like getting too close to a magnetized screwdriver, so I'm at a loss.

 

Stop codes I have gotten:

IRLQ not less or equal

Memory management

attempted write to read only memory

kernel security check failure

kmode exception not handled

Try re-seating the RAM, had a lot of issues with friends getting problems just like yours and it was a dead stick or slot

Yay... Problem solved. One stick is bad. Somehow. Probably my own fault mishandling it. Tried swapping slots and now it won't even boot with that stick in. Take it out and try with only the other 4GB stick and it boots and lets me log into Windows, albeit not as responsive. Tried swapping back to the previous slots and it won't even boot as it did before. Guess I'll be looking into some new ram sticks
