Just killed my bc250?

Hi

Have been playing with it for couple days, installed Bazzite, governors, printed fan mount put ptm… in the end got around 71-73 degrees in cp2077 benchmark. But then in one run it switched off in the middle, atx ps also switched off. No luck with restart, even with different ps. The only leds are power and reset, nothing on the pcb is on. Cleared cmos but it’s the same.

Could it die completely ?
