The computer Will bad power strip cause computer errors question is a Dell Optiplex I could hardly get it to do anything.

Tried to shut it down, and it just hung on 'saving windows settings,' so I forced it to shutdown. I gave the user a loaner and brought this one up to my office. When I tried to turn it on, the power light blinked at me, but it did not turn on. The lights on the motherboard were on though. I pulled the power supply out of anotherand swapped it with the suspected bad one. The computer turned on and seems to be running like a champ now. It is absolutely essential that the power supply Will bad power strip cause computer errors the system be supplying the voltages within a very narrow range.

If it is intermittently unable to meet the required voltage levels, you will see many different symptoms depending upon what voltage is bad and by how much. Modern CPUs will slow down if over temp is detected. Also, bad voltages to peripherals, like hard drives, may cause recoverable read errors that cause nasty slowdowns as the drive goes through its retry process.

Is the power strip one of the "energy saving" type that has a "master" receptacle, along with the other Will bad power strip cause computer errors If so, and the computer is not plugged into the "master" receptacle, the rest of the power strip will remain powered down until a load is sensed on the "master" receptacle.

Try pushing it another time after a few seconds. And another time. This behavior is typical for shoddy capacitors. Chances still are the hardware problem is in either PSU or motherboard, but other components can be the culprit too.

What components? Hate to break it to you, but every component inside your pc or even attached to it can be the cause. That's the way to go for you though: If not a capacitor problem this can be caused by any other component or peripheral device. You can really do without that DVD drive, front panel audio, case and so on fan for a few days, right?

Believe it or not: That's how the Pro's fix this too. There is no magical trick they have up their sleeve to fix these kind of problems.

We for example just have a warehouse full with a shitload of new and used replacement parts and swap them out until the hardware problem is solved. Then we know what part was defective. We have had customers bring in their box with these symptoms only to find no problem at all. When the box was plugged in at home the problem occurred again only to be finally diagnosed as caused by for instance a defective display. Or a printer, or a I don't know, that is an odd one. Astute Technology Solutions is an IT service provider.

I have not had too much experience with this, but I did have a laptop do that to Dengudu x xx nise storrs and when I replaced the battery it all worked fine. I know that a power supply going out has also caused issues with desktops I have worked on in the past. Unfortunately, I cannot shed any light as to why? I would assume it would be due to supplying power to the motherboard. If the PS died while the system was on, it may have caused high-draw Will bad power strip cause computer errors to stop, Will bad power strip cause computer errors the HD.

A bad PS will usually either allow the computer to work or not work, as you discovered when trying to restart the system. I think you made the proper diagnosis. I have seen this on many 's 's too. Those power supplies are terrible but there are no aftermarket options that I know of.

Hook the old power supply up to a tester or use a mutlimeter and check the output. As mentioned by Chris, the components could be getting enough juice to function, but not as much as needed to function properly. We had a TON of s at one of my previous employers.

I'd bet you five virtual dollars that if you pull that motherboard out it's warped. A dying PSU can definitely cause performance issues.

I once had a custom build come in for diagnosis, and the performance was terrible. While running some diagnostic tests, a capacitor in the PSU exploded!

I was standing right next to it, and I ran for my life! It sounded like a gunshot! Luckily nothing was damaged by the failure other than the psuso we replaced it and ran the diagnostics again. System performed much better, and was released with a clean bill of health. When the voltages are out of whack, the system may still run, but not optimally. It will run, but not very well.

I've seen so many weird PSU issues that I pretty much won't ever rule one out. I'd just replace or swap it out and see if that changes anything. I've had a bunch of memory problems recently. Memory goes bad, no errors shown, slow as heck.

Dell Openmanage software finally caught an exception, that's what gave it away Here is a good power supply testing tool. This is not logical. Reason dictates that a power supply either works or the computer doesn't run at all.

Live and learn I guess. As a tech, I too have seen this odd behavior. A proper power supply tester should be part of every tech's arsenal for diagnostics. Thanks you for all of the responses. I had started this conversation with one of my coworkers, at first he didn't really think the bad power supply could have caused the issues we were seeing, and I was really unsure of it myself, but once we started talking about it, the idea of decreased voltage to a hard drive or processor seemed plausible.

So I thought I would pose this question to the community and see what the experiences of others has been with an issue like this. Thanks for the explanation. A nice reminder that just because something is Will bad power strip cause computer errors doesn't necessarily mean it's working properly. I think if the auxiliary 12 V supply isn't there the older just coming into ATX 2.
