My warranty ran out 5 days ago and suprise suprise when I turned on the pc the alien ware logo comes up then the screen goes blank. I have checked the bios, have got into recovery and tried reinstall windows but still not booting os. It's driving me mad. I am not a regular pc user and haven't turned it on for about 5-6 weeks. Annoyingly if I would have used pc earlier it would have still been under warranty. I installed Windows 11 a few months ago and am wondering if this could be a bad Microsoft update as it has been running fine up until a few days ago. My open uni degree starts again in January (what I use the pc for) and I'm panicking that it's not going to be sorted out by then.  I have spent over a grand on a PC that has suspiciously packed up a few days after warranty expired. Please can anybody help me get back into my os again
