problem Random reboot GTX 1660TI

[MusabaN]

When I start playing games, it randomly reboots, sometimes after a few hours, sometimes just after a few minutes. The graphicscard works in other computers, and I've used a GTX 990, and the computer works. The BIOS is updated to the latest drivers. The 990 card draws more power, so I guess that should rule out the possibility of it being a PSU issue. Clean reinstall of windows is done, the drive its installed on is an NVME drive, its even a bought copy of windows 10. Anyone have any suggestions or have had a similar issue?
