Check the computer temperatures with BIOS. Not all BIOS systems include the temperature monitoring options, so you might or might not succeed with this step. To get into the BIOS - turn the computer on, and while it's booting, look for a line that says something like "Press F2 to Enter Setup." Press that button to enter BIOS and look for a tab named something like "Hardware Monitors" or "PC Health." Check your computer's manual for system specific instructions.
