Most common issue for this is a bad motherboard, power supply, overheating or bad video card. Depending on the type of system you have one may be more likely than the other. In a basic non-gaming computer, usually the motherboard goes first. Check the motherboard for any physical issues, capacitors often go bad when things shut down this way. May also be the video card if it's an add-on one.
You will need to provide more information if you want some help. Motherboard, cpu, cpu cooler, graphics card, power supply, operating system, memory, cable connection to monitor. Describe where the yellow light appears. Have you recently made any changes to your computer.
