Question

you have just finished upgrading your desktop systems cpu. after running for about 15 minutes, the system spontaneously shuts down. which steps should you take first to troubleshoot the issue? (select two.)
check the power - supply voltage switch.
remove any unnecessary components and run the system.
replace the power supply.
check the cpu fan power.
make sure that you used thermal paste for the cpu.
i want to review this question later. (optional)

Explanation:

When a system shuts down spontaneously after running for a while, checking power - related and cooling - related aspects is crucial. Checking the power supply voltage can identify power - delivery issues. Checking the CPU fan power ensures proper cooling as overheating can cause spontaneous shutdowns. Removing unnecessary components doesn't directly address the shutdown issue immediately. Replacing the power supply is a drastic step without first diagnosing. Using thermal paste is more of a preventive measure during installation rather than a first - step troubleshooting for an existing shutdown problem.

Answer:

Check the power supply voltage switch.
Check the CPU fan power.
