You are troubleshooting a computer that reboots at strange times. Even when you try and access the CMOS setup, the computer will reboot. What should you check FIRST? Check for blown capacitors/ Check to see if the case fan is spinning/ Check so see if you operating system is corrupted/ Replace the CR-2032 battery

CHECK FOR BLOWN CAPACITORS Correct Answer:Do a google search for "blown capacitor" and you will see exactly what I'm talking about. That is a rough situation there. When this happens, it will short circuit the conductors that are carrying power, causing random reboots, among many other types of errors. Incorrect Answers:While checking to see if your case fan is spinning is a good idea, it's not the FIRST thing to check for in this scenario.Replacing the CR-2032, or CMOS battery, will just give you a brand new CMOS battery, it won't stop the reboots from happening.We can't even stay in the CMOS setup screen before the computer reboots, so don't go troubleshooting your OS just yet.
