So the past couple of days my machine was rebooting itself sporadically, then after I dusted it, it shut down when loading windows. I had a hunch is was the PSU so I replaced it and so far it works fine.
But another machine in the same house (on a different line) is experiencing similar problems now. So my question is what is going on?. Other than Christmas lights there have been no major changes to the electrical setup here.
The power to the machines is on direct lines, there is no ACP or surge protector (although one has a power strip) But it has been like this for years, so I don't see what the cause could be
Get a volt meter and check to see you aren't getting a drop in voltage. This can be very dangerous. Electrical fire is a possibility. I don't mean to alarm you be your issues may be very serious. Unplug some of the christmas lights until you check.

I put a volt meter in the socket, when the machine is off, I get 119.9-120
when it is on it hovers between 119.3-120
Again it still shuts off after 2 mins or soThanks for the help...

That voltage is good. When you dusted the computer out did you unplag and then take static precautions? Hope you didn't use a vacuum cleaner.

It could just be bad luck.
Or it could be fluxuations in the electrical service. Just because it didn't happen in the few seconds you were using a volt meter doesn't mean it's not happening from time to time, or that didn't happen one time last week...

I agree with the above statement. It also could just be coincidence that the power supplies could be going out on both PCs at the same time.
Jesus can change your life for the better!!

When I dusted I used all the proper precautions; compressed air with quick shots etc.
Yes it could be coincidence I thought of that too. Perhaps though it could be that there was a period of time where the voltage was fluctuating and that damaged the PSUs?

"there is no ACP or surge protector".
That is not good. You should use a good surge protector on all your systems. Consider speaking with an electrician to install a whole house surge protector. This will protect home appliances in addition to your computers. The cost is surprisingly reasonable.

Good advice, OtheHill. I'm picking up my one year old microwave from repair after it lost the inverter, probably due to a power surge. Since it has a microprocessor in it, much like a computer, I will be putting in a good surge protector for it, now.
Never, I mean, never, run a computer without surge protection. The power supplied is never perfect, especially here in the mid-west with ice storms, etc. Protect yourself, AND your beloved electronics equipment. You won't be sorry.

A positive attitude won't solve all your problems, but it will annoy just enough people to be worth the effort.

One last note on this topic, all surge protectors are not created equal. The ability to clamp down is stated in the specs. Lightning has huge voltage and current potential. IF a surge protector is subjected to a very large surge it should be replaced, as it no longer cn provide the original level of protection. The protector is sacrificial.
