Hello, i recently bought a 'refurbished" Lenovo Legion T5

Specs:

CPU: Intel i9-11900F 2.5GHz/8C - SSD 1TB m.2 2280 PCIe3x4 Samsung OPAL - HDD 1TB ASM 7200 DT3 SATA3 STD - GPU: MSI RTX 3070 8G/D6/3DP/H/LHR - Ram: 2x16GB DDR4 3200 UDIMM Kingston - Motherboard: Intel Rocket-Lake B560 WIN DPK

After installing the pc, for some reason it keeps rebooting at a random moment, also it was very slow and apperantly windows was installed on the HDD. (By default?) So i reinstalled windows on SSD and it is running very smooth but still keeps randomly rebooting. Sometimes my screens just goes black and the Pc seems idle (fans and lights keep running).

The computer already went back to Lenovo and they changed the motherboard. Nothing changed, the problem still remained the. I ran hardware diagnostics and everything passed. I tries different RAM modules, still no solution.

When i run windows in safe mode it seems to be running just fine. Any idea what might be the problem or how can i troubleshoot this problem? It seems to be software related. Maybe install windows 10 instead of 11 because of driver problems?

I can still return de computer and get my money back for 2 weeks. But it was such a good deal (to good to be true) that i really want the computer to work instead of getting my money back.

I’d like to hear your thoughts
