m16 R2, unstable

Hello,

I purchased a new m16 R2 laptop in February of this year. I travel for work often and this goes with me. When I first started using it it was running very slow. I figured it may have been all the bloatware that comes loaded on these so I did a full system restore. It seemed to run better after that. I used it for 2 weeks and noticed occasional slowness, but nothing too crazy. Thinking back on it, I really should have returned it but I got too busy with work and travel and didn't have time to mess with it.

It has sat until I went on travel again these past 3 weeks. It has been running terribly, and I have noticed when I have multiple browser tabs open it really struggles. A few nights ago the screen flickered, the computer locked up, and shut itself down. It would not turn back on. After about 10 minutes I was able to turn it on and received an error saying the BIOS clock was not set correctly. I set the clock and after a few restart cycles Windows finally loaded.

I started monitoring the Alienware Control Center and noticed CPU temps would occasionally spike from 65-75C to 99C and stay there for a few seconds and then go back down. Not sure if this is considered normal or not. Overall system stability has been poor. It will run good for most of the day and then start to act up if I have multiple browser tabs open, and especially if theres a few videos (paused).

I have been working with Dell tech support. All the BIOS hardware tests have passed, and the Dell SupportAssist hardware checks have passed as well. It's hard to get them to dispatch a technician when there is no obvious issue with the laptop that can be replicated.

Does anyone have any suggestions on things I can do to try and replicate the issue so I can have this looked at? For reference the CPU is Intel(R) Core(TM) Ultra 9 185H, 16gbs of RAM, and the graphics adapter is a GeForce RTX 4060.
