Question Pc not booting into windows or bios

May 30, 2023
My pc stopped working a week ago and I tried everything such as reseating ram, taking cmos battery out, put new thermal paste on cpu and gpu.

When i boot my pc on, the fans spin and the fans spin really fast and then it slows and it just repeats that. It also does not boot at all not even bios.

Could it be my power supply?
