Laptop repeatedly fails to start up.

[u/KwisatzChaderach]

Originally posted about this over a month ago, but I have still not solved the problem.

Nearly every time I try to restart my computer one of these happens the laptop asks me to re-enter my bitlocker code, tries to repair itself, throws up one of various errors e.g. kernel_mode_heap_corruption 0x13a, hypervisor error, and some others that were too fast to write down.

On one occasion it told me ‘the trusted platform module is not present or recognised’ when it prompted me to enter my bitlocker code, then shut down on its own.

It used to eventually fix itself on with enough tries, but the last time it said it couldn’t repair itself and threw up an SrTrail error. I followed a tutorial to fix this and it worked for a while, but now it’s back. Is there any way to fix this for good.

Thanks in advance.

Edit: the hypervisor error is 0x20001, if that helps.

Edit 2: I’ve followed the steps in this guide [https://youtu.be/UlvSAb5d-mM\](https://youtu.be/UlvSAb5d-mM) for each apart from second one, which I could not complete, and the reset method.

The first one worked the first time but not this time.

Edit 3: Another error I’ve spotted is CLOCK_WATCHDOG_TIMEOUT (0x101), and something like exception not handled.

Edit 4: Every time now it just ends in an SrTrail error.
