Once I did #1 which was about $1000 down time really dropped. Mechanical Wear - 8" floppies, regular floppies, fans.

Got like 18 years out of a Mac computer with just a floppy and fan failure.Ģ. Power conditioning - I used OneAC power conditioners with an Isobar. When I did in-house repair of micro-computers that were ties to our laboratory measurements, the failures fell roughly into the following categories:ġ. Most other hardware failures that were power supply related were random hangs or reboots that went away when the power supplies were replaced, but it took high end digital storage scopes to detect any problems with the voltages. Historically, most of the failures we noted were complete power supply failures of one or more of the voltages. And then deviations from that over time might be a good indicator of an looming failure. Getting a picture of the DC voltage and the measurable AC noise level would be a good data point to have. I am not trying to be overly negative, and I think your idea has merit.

drop out caused by a data bus driver switching. So a failing capacitor on the 3.3V rail might not have any indication of failure at the 500KHz switch frequency, but could not prevent a 10 nsec. And the bigger problem is that the different components drawing high instantaneous currents are what cause the voltage drop outs that result in failures. So the the AC ripple, is really more of a high frequency noise. The outputs are from high frequency switched mode power supplies. The problem is that it is just not that simple.

On the TV however i probably wont install a measuring unit, just on the PC. On the TV, the TV would not boot anymore due to the automatic shut down due to the bad caps. What happened last time the caps went bad was the power supply would shut off as soon as it tried to start the computer, so the computer would not boot anymore. If the AC measurement changes too much i know the caps are going.

What i plan to measure is at least the +12v and +5v lines, and also provide AC measurement for the ripple on the two lines. So now i think i might just build one, probably with a Nano because that would go quickly. He mentioned that measuring the ripple would tell us if the caps were going bad (something that i definitely want to know because i've had failures in the past only because of the large filter caps). I just got another idea from Nigel however, which changes my total outlook on this matter now. I have the VCore voltage covered, so i dont need to measure that, but the +12 and +5 lines would be best for me to measure. I was just looking to monitor the lines so i know if something is going wrong before it goes wrong completely.
