Good thoughts there from Helix and Jim.
On the hottest day of the year, one of my hard disks shut down - a 7.2K spinning disk. Not the CPU or graphics card, or system disk (SSD), just the data drive. I assume it was due to the heat, although tests didn't indicate an overtemp event. Everything is backed up, but I didn't need to restore, as the disk came back once everything had cooled down. I will continue to use it, on the basis that it's backed up regularly.
My experience has been that BSODs in PCs are very often down to faulty memory or failing PSUs in particular.
