Help with Wintel hardware.... :(

I have a Compaq  933 Deskpro EN and it worked fine for the first 2 months I had it. Now, I moved the machine, unplugged it and disconnected all the cables. Before I moved it, I plugged it in, so as to remove a CD I forgot in it. Now, after three days of not plugging it in, I had my mom carry it back to my place and when I set it up, and hit the "start" button(hardware not OS), nothing happens. No light, no NOTHING.

I have the plugs in the right place but I've switched the OS and monitor plugs several times and still nothing is happening!

WTF is going on? She tells me she didn't drop it. I know I didn't. Could just sitting it on its side do that to the desktop?

Seriously, need help.

I'd first recommend opening the case and reseating any cards that are in there.  Also make sure that the RAM and CPU haven't become loose.  These are about the only things I can think of that can prevent the computer from powering up at all -- short of a bad power supply, of course.

If that doesn't work, I'd next suggest that you remove any cards except for video (assuming it's not on-board video).  If the computer fails to boot at that time, then I'd say a tech should look at it.

Could just sitting it on its side do that to the desktop?

No.  But that doesn't mean it wasn't jarred or even dropped while you were away.  (Not saying your mom isn't telling you the truth, but a drop could cause this problem.)

hit the "start" button(hardware not OS)

That's typically called the power button, FYI. ;)

I've switched the OS and monitor plugs

The OS requires a plug now?  :confused:  Of course I surmised that you're referring to the power cord for the computer itself.  It just reminded me of people who point to the computer's case and call it "the hard drive."  ;)

Hope this helps.

Hardware training 101...the ultra-crash course. Hmmm...Wintel....crash. How...appropriate.

But seriously, it's a new machine. I DID crack her open, against everyone's wishes over here and I DID confirm:

1. The RAM seems to be seated ok.
2. I removed the vid card and re-seated it. There seems to be no nic. My guess is that it's integrated into the mobo because all my PCI slots seem empty.
Now I can't tell if they're both seated right but I CAN say that they're not crooked or anything.

3. Then, I checked the wires from the POWER button(happy?) to the mobo. They're connected but I unhooked them and plugged it back in, careful to align the prongless spot with the blocked hole.
Then I unscrewed and checked the wires on the button themselves. The black wire made a snap sound but seems firmly on there.

4. I've got the psu unscrewed and I'm trying to figure out a way to start it wiout anything else. Is that possible?

Give me a break, this is the first time I've taken a machine by myself apart(wiout my bosses or sys admins).

I'm doing my best. :(

Dumb question but... a lot of PC boxen have a "hard" and a "soft" power switch.   If the hard power switch (usually a small rocker switch) is off, the big ol' power button on the front ain't doing nothing...

You have to short across two of the wires in the PSU-Mobo lead to start it with no mobo. Bascially, get a paperclip and put one end in the green wire's hole and the other in any black wire's hole. Then you can turn on the power and the fan should start.

More advice in Case and Cooling a while back.

Notice the ON/OFF switch.

Turn it ON. Then press the Power button.

Very good point, Riso.  (And JR who also mentioned it.)  It's often difficult for me to drop down to the lowest level of end-userdom.

Assuming this is a newer machine (i.e. PentiumII-era or later) that supports auto power-down, then this would indeed be an issue.  There's a main power switch on the PSU which is typically left in the "on" position.  It's quite easy to move that switch to the off position when lifting/moving the computer, unless you're one who always lifts the computer from the bottom.

assuming the psu does not have its own switch turned off (it shouldn't have one, i can't remember seeing one on modern oem machines for the very reason that it might get turned off), and you've made sure it's set for 115v instead of 220v, and you're sure it's plugged into the mobo correctly... try shorting the power switch leads on the mobo. if that doesn't work (and you verify the psu works by shorting the correct pins on the atx plug, i *think* it's wire 14 and any black ground but i'm not sure), then pull every card out and disconnect all cables. if it fails to power up with nothing but cpu and power lead plugged into the mobo... take a guess as to which component is in question.

if it *does* activate the psu like that, then shut it down and add the ram. test. add video card. test. add other cards. test. add devices (being careful to plug them in the right way). test. see where this is going? :)

or you could just call compaq if it's still under warranty.

RESPONSE:

Sorry but I was out of town(Can you believe this happened the night before I left?!).

There is no soft/hard power switch mechanism. There is only *one* power button but thanks for trying Jeremy.

A. I'm not shorting anything.
B. I'm not shorting anything.
C. The machine is a loaner AND I don't want to void the warranty.
D. I'm not shorting anything.

But thanks for the help. Really. :)

Me points to the PSU and shows Riso that there is *no* "on/off" switch, simply an orange switch for 115/230 for use as a tower or as a desktop.

Me hears Riso say "d'oh".

Harbinger ...

Very good point, Riso.  (And JR who also mentioned it.)  It's often difficult for me to drop down to the lowest level of end-userdom.

True. Still, I'm content that most ppl on Ars basically gave me the same diagnosis I had made, considering my limited hardware skills. I knew it was the PSU. I have no doubt. While it is an empowering sensation, I still prefer the ease of never having to open your machine. ;)


Assuming this is a newer machine (i.e. PentiumII-era or later) that supports auto power-down, then this would indeed be an issue.

It is. There is no manual PSU switch. Short of rebuilding the PSU myself, I'm going to need outside help.

There's a main power switch on the PSU which is typically left in the "on" position.  It's quite easy to move that switch to the off position when lifting/moving the computer, unless you're one who always lifts the computer from the bottom.

Uh, no there isn't. Unless it's inside the PSU case. Is that possible? If so, what would such a switch look like. On the metal case of the PSU itself, there is no switch other than the 115/230 and the machine won't start under either.


assuming the psu does not have its own switch turned off (it shouldn't have one, i can't remember seeing one on modern oem machines for the very reason that it might get turned off), and you've made sure it's set for 115v instead of 220v,

It doesn't and I did.

and you're sure it's plugged into the mobo correctly...

I am, Pauli.

try shorting the power switch leads on the mobo. if that doesn't work (and you verify the psu works by shorting the correct pins on the atx plug, i *think* it's wire 14 and any black ground but i'm not sure), then pull every card out and disconnect all cables. if it fails to power up with nothing but cpu and power lead plugged into the mobo... take a guess as to which component is in question.

E. I am not shorting anything.


if it *does* activate the psu like that, then shut it down and add the ram. test. add video card. test. add other cards. test. add devices (being careful to plug them in the right way). test. see where this is going?  

Unfortunately, yes. I rebuild the machine. I *literally* ripped out the mobo and put it back together. It's not the vid/hd/RAM/proc...etc. It's the PSU. I'm fairly sure it's fried.

or you could just call compaq if it's still under warranty.

Bingo! I called them today. They were *very* nice. I'm hoping I'm under warranty. If so, I simply have to call them tonite(24/7 service) and have an appt for someone to come by tomorrow or Wed. Then they fix it.

I hope.
But thanks for the suggestions.

Oh, and thanks Pizza. :rolleyes:

That's quite common these days actually. You've probly got to look pretty hard for a soft power PS with a hard switch as well.


and the machine won't start under either.

:eek: :eek2: :eek:

No, no I daresay it wouldn't ever start after having ever been set to 220/230 and turned on. My uncle tried that, once. For him it was a new mobo + CPU + PS. Be ready to call compaq back if you tried too much stuff with it switched to 220. (if it was already well and truely dead before then, it may not have hurt anything, but there's no telling until you have the new one to try out...)

Good Luck.

Hit, the manual, which my sister tossed out...along wi my copy of Win 98 >(, indicated that the 115/230 switch was *only* from switching between tower and desktop modes.

They are mad. Frakenstien humping Dr. Jekyl style mad. INSANE. 115/230 switches are for electrical current. 115 in the US, 230 most everywhere else. If the manual said differnt, it's absolute madness. The only thing that should need done to switch from tower to desktop is some messing around in the case to make the external drives face the right way. (I've seen some of Compaq's older desk/towers. They're a pretty neat idea.)

As for the manual + CD, I'd have her searching garbage bags for them ;) (I too lost my $150 Win 98 SE disc not long ago. I'm still pissed.)
