I've been using my Windows 11 laptop for about 5-6 days, and now it won't turn on properly. After charging it, it managed to power up, but then it froze completely. I tried to restart it, and I ended up getting an error with the Stop code: KERNEL_DATA_INPAGE_ERROR (0x7A). I tried running some commands, including fixmbr, and now I'm getting a SYSTEM THREAD_EXCEPTION_NOT_HANDLED (0x7E) error. Does anyone have suggestions for fixing this issue?

From what I gather, it sounds like your laptop might have experienced a hardware failure, especially with the charging issues you mentioned earlier. You might want to check your power supply first. If you’re not familiar with the technical stuff, it's understandable to feel stuck; DIY fixes can sometimes complicate things further. Have you tried any recovery methods yet?
It sounds like something might have gone wrong with your SSD or disk setup, especially after running those commands. Make sure you have your data backed up before making any changes, as messing with the BIOS or disk settings can cause data loss. Also, do you have an MBR file system? That's a bit unusual these days, so let’s clarify that first.
It might be worth trying to boot from a recovery USB again and running some diagnostics. Sometimes startup repair does help if it finds the issue. But if all else fails, you might want to consider taking it to a professional, especially if the repair tutorials aren’t working for you.
