I'm not familiar with ftdisk events because when I started to work professionally in this field, XP had already become an antique, but if it's anything like the "disk" event in Win7 and later, then the lack of it does not prove that the disk is OK. Have seen so many machines without disk event but with collapsing disks.
The PSU hypothesis sounds plausible, however it should manifest itself in stress tests as well, particularly in CPU and GPU tests. That said, I mostly happen to service laptops which is like 95% of computers coming into the lab, so my experience with stationary machines is limited.
