Question:

What could cause a PC to stop working, emit a burning smell, and fail to boot up after playing a VR game?

I was testing a VR game on my PC when it suddenly shut down. I noticed a smoky odor coming from the PC and it did not respond to the power button. I inspected the CPU and GPU and they looked normal. I need some guidance on how to troubleshoot this issue, as I have recently repaired another problem with my PC.

Answer:

A PC that suddenly stops working, emits a burning smell, and fails to boot up after playing a VR game could have several possible causes. Some of the most common ones are:

• Overheating: Playing a VR game can put a lot of stress on the PC components, especially the CPU and GPU, which generate a lot of heat. If the PC does not have adequate cooling, such as fans, heat sinks, or liquid cooling, the temperature of the components can rise above their safe limits and cause damage. This can result in a burning smell, a sudden shutdown, and a failure to boot up. To prevent overheating, it is important to monitor the temperature of the PC components, ensure proper ventilation, and clean the dust from the fans and heat sinks regularly.
• Power supply failure: The power supply unit (PSU) is responsible for converting the AC power from the wall outlet to the DC power that the PC components need. A faulty or inadequate PSU can cause a variety of problems, such as voltage fluctuations, short circuits, or power surges. These can damage the PC components, especially the motherboard, which is the main circuit board that connects all the other components. A power supply failure can also produce a burning smell, a sudden shutdown, and a failure to boot up. To avoid power supply failure, it is advisable to use a high-quality PSU that can handle the power demands of the PC components, and to use a surge protector or an uninterruptible power supply (UPS) to protect the PC from power spikes or outages.
• Hardware malfunction: Sometimes, a PC component can malfunction due to wear and tear, manufacturing defects, or physical damage. This can cause the component to stop working properly, or to interfere with the functioning of other components. For example, a faulty RAM module can cause memory errors, a faulty hard drive can cause data corruption, or a faulty graphics card can cause display issues. A hardware malfunction can also cause a burning smell, a sudden shutdown, and a failure to boot up. To diagnose a hardware malfunction, it is helpful to use diagnostic tools, such as Windows Memory Diagnostic, CHKDSK, or Device Manager, to check the status of the PC components, and to replace or repair any faulty ones.

In conclusion, a PC that stops working, emits a burning smell, and fails to boot up after playing a VR game could have several possible causes, such as overheating, power supply failure, or hardware malfunction. To troubleshoot this issue, it is necessary to identify the source of the problem, and to take appropriate measures to fix it. If the problem persists, or if the PC components are severely damaged, it may be wise to consult a professional technician or to buy a new PC.
