Sticky 

Computer down...

All right, I am in need of some assistance/guidance/advice because of this:

I tried to turn the computer on Thursday night and nothing happened. Not a whirl of any drive, not a light of any source, not the slightest hint of any life whatsoever.

So I proceeded to unplug it from the battery backup directly into a wall outlet -- nothing. Unplugged all nonessential peripherals to no avail. Turn off the master switch on the power supply and unplug the unit for a while, then reset -- nope.

Through advice of the computer manufacturer, I replaced the power supply and happily pressed the ON button only to have hopes dashed.

Now the old power supply had a strange whine/whistle to it when turned on and the new one did not -- but both lit up a small green LED on the mother board in the same fashion.

So it may just be the switch, or it may just be a fried :C drive, but my limited knowledge and access to testing options has left me little choice.

Any suggestions? Like how to troubleshoot further, or where I might be able to bring it for a "professional" workover?

By the way, all image files are tucked nicely away on the DROBO so there is no worry there.

Any and all help is greatly appreciated and I thank you in advance!
get a Mac? Really, been there last summer with our pc laptop, not a good experience. This sounds like a question for Shawn.

I have already done the Mac thing for a lot of years and found the Win2000 and XP machines to be much more stable. I got really tired of Macs bombing on me or locking up when I had them thinking too much for them to handle. This is the first real issue I have had with any PC I have owned for 8+ years.

My first guess would have been that your powersupply just went out, which is pretty common, but you already tried that with no success.

From the sound of it nothing appears on the screen? If it was just the hard drive failing you would still see the bios or computer manufacture logo when turned on. So your drive is most likely fine.

I guess my next guess would be the front switch on your computer that connects to the mobo to turn it on. Those occasionally do go out, you could try just hitting the power button a bit harder or else try a new switch if you have one.

What Karl said.

"I got really tired of Macs bombing on me or locking up when I had them thinking too much for them to handle."

You were on OS 9, weren't you? "Crashy and slow" hasn't been a way to describe Macs for me years. Now, if you have a problem with "extremely proprietary" that's another story.

I have taken all covers off and removed the switch (kept it connected) and toggled the switch directly -- nothing. And, unfortunately, I don't have another switch -- plus it looks like the case needs to be torn apart to get the switch replaced anyway -- I'm sure that can't be right, but it looks like it.

So, do you see anything on the monitor or not?

Based on the information in this thread so far, I'm going to put my money on a bad switch. These do fail, but the percentage of them that fail is so low that I have seen a few different cases where the power switch could not be replaced without completely disassembling the case.

I would test this theory before tearing anything apart though. The wires that run back from the switch to the motherboard should be fairly easy to trace out. Once you've found the pins where they connect to the motherboard, you can attempt to start the machine by removing the connections and manually shorting the pins together. If it starts after this, you've just got a bad switch, which can be replaced after a trip to Radio Shack.

I understand if you're hesitant to start poking around inside your tower with a screwdriver while there is power applied. It is a delicate thing to do, but it isn't outside the realm of "safe things to do". Just don't do it while you're all jacked up on Pop Rocks and Mountain Dew.

provide the specifications of the power supply. i probably have a spare, or one that we can use to zero in on the real problem.

do you have an electrical tester/meter? do you know how to use it?

please classify the level of urgency, based upon when you MUST have this system back on-line...

i cannot help you today, but can swap labor with you... time spent on your computer is time away from mounting photos... which you can help me with...

UPDATE: NEW INFO, but still is completely dead.

Jason: Thanx for the link -- through that I have verified that the original power source is bad, and the new one is working fine.

Shawn -- dead as in no sign of life whatsoever, so nothing is coming up on the monitor (not even getting close to a point where it might start displaying something.)

Brandon -- I am going to attempt the manual start you described.

Rich -- stay tuned and I might just be taking you up on the offer!

As you can see here, taking it apart is not an issue with me:

I just want to add that usually those front switches are momentary, so jump the ends with the end of a screw driver and if and when it comes on take it off, or else you might shut it down again or something.

Manual triggering of power on mobo FAILED. The new power source is hooked up, plugged in, and on. The connections follow exactly how the other one was oriented (and follows the mobo manual) except for non-essential drives, made 'manual' connection between the 2 correct pins where the power switch was connected (with and without the other connections made -- the 'reset' and the leds) and still not even a glimpse of life.

Golly Dang gosh darn sugar...................

huh.... maybe it was a power spike that fried your powersupply and mobo or something?

Looks more and more like I got a double whammy.
