by: Steven Stoddard Power Supply If you suspect your power supply is giving you trouble, make sure you check it out fast, because power supplies can make trouble with the rest of your system as well. Irregular voltages sent from the power supply can short circuit and overheat your components thus frying them and making them unusable. Some faulty power supplies have even caught on fire, but if you’re lucky it might just smoke a little and start to smell. A few signals that your power supply is bad or is going bad would be erratic and seemingly random system behavior like system hangs and crashes, and burning smells along with smoke. If you recently upgraded your system or added new hard drives, disk drives, a graphics card or anything for that matter, be sure to check if your power suppl
