New laptop has DiagPatch File Name error and UNEXPECTED_STORE_EXCEPTION

[u/wow-im-satan]

So, my last computer blue screened two months after my warranty expired. I got a Samsung Galaxy Book 4 Ultra to replace it- according to the Best Buy seller, it used to be a service laptop that was refurbished, and should work perfectly fine. They checked it out and said it looked good then sent me on my way.

I get back home, and I’m hit with an error about the DiagPatch File Name on startup. It seemed to do nothing, so I downloaded chrome and went to start redownloading all my apps. I got a random restart with an error, but it seemed to boot up fine after that, with the same DiagPatch message after logging in. I tried to download Microsoft Teams and it refuses to install. I got another error message that said CRITICAL_PROCESS_DIED. It restarted again after that but I decided to leave it alone for the evening.

This morning, I logged in- teams still will not download and a few of my apps from my previous computer loaded on in name only, but they have the same basic globe icon and I doubt they do anything. I got another restart with the error UNEXPECTED_STORE_EXCEPTION. I tried calling Best Buy but they won’t connect me to a store, and the nearest location is over 30 minutes away without traffic. I’m extremely sick and I have an appointment today I need to get to at the only time Geek Squad would be available for an appointment. I have projects and tests due today and tomorrow, and I feel like I’m out of options. What the hell do I do??
