The unit was finally returned for repair, though I've since decided they can keep it. I just want out. Too close to the 30 days and something tells me all they're going to do is re-install Windows for the 3rd time. Lost interest in Dell completely.  Asked for a refund and was told the following by support: The refund was already approved. We already process the refund. And when asked what the amount would be and why I hadn't had anything by email to confirm this, I was told; It's equivalent to what you purchased from us. After that, I went to check with Customer Care and was told; Once you have the device back we will check for refund approval and raise the refund request where first the system is pulled back to Dell and then the refund request is initiated. What a game this is and a total waste of time. They ship it back to me and then they refuse a refund.  Right!
I've had my XPS 8950 with i7-12700K, 3060Ti for two weeks and every single day it's frozen up on me. Just usual standard ms apps, not even gaming and the first time it happened was just a few minutes after turning on for the first time. So annoying!  Friday it managed to stay up for 7hrs, but this morning.... 3 freeze ups in 2hrs so far. Dell "Premium" support have been giving me the run around for over TWO WEEKS, having me do all kinds of things.  Clearly feels like a hardware issue. I've even done a fresh install of Win 10 (downgrading from 11) and the issue persists. I've not had it in safe mode, but happens otherwise even with just the wired dell mouse and keyboard as the only connected devices. Doesn't matter whether I'm actively using it or it's idle and it's totally random, it can take 10 mins to freeze or 6hrs. All the latest firmware, drivers, etc. and I've eliminated the ram. No crash reports, obvs, because it just freezes. Anyone else getting similar? I think I may have tied this down to my Samsung T5 1TB SSD, which was connected via the USB-C port on the back.  The same happened if plug in at the front. However, since removing it, it's been ok for a few hours. I've since plugged it into a standard USB port at the back with a different cable. This was after chatting with a technician from Dell who suggested removing all  USB devices and letting the machine sit in the bios for a bit, to see if it still froze.
