PSUs do not last forever and if you experience power surges, lightning, etc. they could last even less. More often than not some early degradation causes random crashes, when under load, rather than complete blackout. It is not easy to test a PSU without an oscilloscope, but you could look at the MoBo voltages with a multimeter to see if they're broadly within limits and don't drop off too much when a load in placed them. Personally I don't bother measuring voltages. If you take the PSU out of the case and visually inspect its capacitors you may find some have domed tops, an indication they have overheated and are on their way out. A few pennies would buy you a bag of replacements which you can solder in to restore the PSU to its original performance. It used to be Panasonic capacitors were better made and had higher ratings, but I don't know what brands can claim better quality of manufacture these days. Burned resistors are an indication of catastrophic surges, although I have replaced resistors and capacitors on a cheap PSU which burnt out when sheet lightning hit our area one year and worked fine for years after that. Of course, if the problem is with the video card, the PSU won't fix your problem.
