PSUs do not last forever and if you experience power surges, lightning, etc. |
78 |
they could last even less. More often than not some early degradation causes |
79 |
random crashes, when under load, rather than complete blackout. It is not |
80 |
easy to test a PSU without an oscilloscope, but you could look at the MoBo |
81 |
voltages with a multimeter to see if they're broadly within limits and don't |
82 |
drop off too much when a load in placed them. |
83 |
|
84 |
Personally I don't bother measuring voltages. If you take the PSU out of the |
85 |
case and visually inspect its capacitors you may find some have domed tops, an |
86 |
indication they have overheated and are on their way out. A few pennies would |
87 |
buy you a bag of replacements which you can solder in to restore the PSU to |
88 |
its original performance. It used to be Panasonic capacitors were better made |
89 |
and had higher ratings, but I don't know what brands can claim better quality |
90 |
of manufacture these days. Burned resistors are an indication of catastrophic |
91 |
surges, although I have replaced resistors and capacitors on a cheap PSU which |
92 |
burnt out when sheet lightning hit our area one year and worked fine for years |
93 |
after that. |
94 |
|
95 |
Of course, if the problem is with the video card, the PSU won't fix your |
96 |
problem. |
