Infrequent but Regular BSODS: Cause?

[Geek-9pm]

Some things to consider. When everything else fails.
Are all fans running?
Reduce the number of items that require power. Remove the CD.DVD drive.
Remove one or two sticks of RAM. Remove any USB devices that are not needed for most work. Such as a printer. A USB hub. A smartphone charger..

Check to see if the default settings for the BIOS are right  for the CPU and RAM type. Check to see if any settings seem odd.
Check to see if the CPU model is supported by the chaise.
*Explanation, rare, but it is possible somebody replaced the CPU with a model that almost right fro the chip-set. Verify the CPU is really in the chip set list.

All fans are running. Computer load has no effect on this, as it often will occur before there is even anything running, as with the last thing. The computer does have woring fans, though.

I will remove my phone charger and only plug it in when necessary. Good idea. It may have something to do with that!

How would I do the BIOs check? That is one thing I am not sure of.
