(select two.)
look for something that could be causing the new cpu to overheat.
make sure that the power cord is plugged in and that the power - supply switch is in the on position.
replace the cmos battery.
test the power supply using a multimeter.
make sure that the cpu is seated properly, oriented correctly, and locked into the socket.
i want to review this question later. (optional)

Explanation:

When a computer locks up shortly after startup after CPU upgrade, overheating can be a cause due to improper thermal - paste application or cooling issues, so checking for overheating is a valid step. Also, an improperly seated CPU can cause hardware - related startup failures, so ensuring proper seating, orientation, and locking is important. Power cord and supply check is more for general no - power issues rather than immediate lock - up after startup. Replacing CMOS battery is for issues like losing BIOS settings. Testing power supply with multimeter is for power - related issues in general but not the most immediate steps for this problem.

Answer:

• Look for something that could be causing the new CPU to overheat.
• Make sure that the CPU is seated properly, oriented correctly, and locked in to the socket.
