Crashes after open for 20-40 minutes. Reboots then BSOD.

I got this laptop a few years ago, used. I've pretty much always had issues with it, but nothing that keeps me from using it. Normally I have to boot it into the BIOS and then start it from there, otherwise, I get a BSOD, 0xc000000e. But today it's started crashing after I have it on for about 20-40 minutes. Crashes to a glitchy green screen, then reboots, where it blue screens as usual. Might have to do with a Windows update, as I tried to update it right before this started happening. Tough to say, though. Dump files might be a little off, as my laptop crashed again as I was writing this, but I can try and make a new one if you need it. I've tried resetting it through the recovery options, it cancels and tells me there was a problem with resetting.

If I take a while to reply, probably my laptop crashed again, but I'll try to be on my phone as well.

I see you are using an insider release of W10. These new builds do not always have symbols provided for the crash analysis and so troubleshooting is more difficult. Due to the nature of insider builds you should report problems directly to Microsoft for their attention.
