In 2004 we bought two Alienware Area 51 desktop gaming machines. They were nearly identical except one had more RAM, HD, Graphics card, etc. I'll call the stronger machine #1 and the other #2.
Machine 1 was heavily used. Machine 2 was hardly used.
Last year machine #1 died. I started hearing a whistle sound and finally figured out that once I turned off the power supply the whistle stopped. Finally it quit turning on at all. Dead as a doorknob. I figured it needed a new power supply.
In the meantime I used machine #2. Just days later it refused to turn on as well. No whistle or anything. Just dead.
Again, its runtime was probably 1/4 of that from machine 1.
So, did both p/s die at nearly the same time due to age (even though one was used less)? Or did/does Alienware have an embedded kill date to force fixing/replacing Or could the problem be something else other than p/s?
Anyone have ideas or similar experience?
You can test the power supplies with a digital power supply tester. Return machines to a very basic hardware config. After that, start swapping parts and find out what works.
