Model(s) in question are the Dell GX270 Optiplex (all form factors) and less on the GX 280's. Symptoms were like the computer went into hibernating/powersave, you would have to restart; some would restart repeatedly; some would go black screen twice a day or once every two or three days. All would go to black screen. It was very frustrating troubleshooting each one until Dell admitted to a capacitor problem on mainboards manufactered before a certain date.
