PC hardware: Computer shuts off for no reason
Computer shuts off for no reason
by nathanpsz2 - 2/11/06 5:05 PMHi,
I have an hp m1050y with a p4 540 and an ati radeon x600xt.
I turned on the computer this morning, left it on, left the house, and when I came back, it was turned off, but the power light was ON. I'm positive that nobody has touched it. BUT this isn't the first time that it's happened.
My best guess is that it's the power supply (it's only 300W); any suggestions for a replacement? It has to be under $75.
Are you certain that it did not

What power light is ON? The one on the mobo itself is only for the 5 volt standby voltage presence.

First, yes it COULD be
by Ray Harinec - 2/12/06 11:34 AM In reply to: RE: by nathanpsz2the Power Supply, but replacing the HP supply with a higher wattage one may be a little problem because HP sometimes stuffs 10 pounds into a 5 pound bag and one can't simply by any old ATX supply to stick in there. I mention higher wattage because it is generally good practice to install a supply with at least a 50 watt higher rating [but proprietaries such as HP, Compaq, etc make that difficult].
You have the system, thus you can see if it is a standard ATX [basically a rectangular "cube", didn't want to say parallelapiped, LOL] or one of the HP types that have the fan housing sticking up as a separate appendage [not separable]..
The other issues may be the video card overheating [if it is a card] and shutting the video down. The other could be the CPU overheating, HOWEVER, in this case the system normally turns the power supply off. [yes the 5 volt standby voltage stays on.
To toubleshoot further we would need to know more about what things are still working when in this powered off mode that still leaves the power LED lighted.
Again, except for the possible HP supply physical aspects it would be Oh so easy to simply put a new supply in.

i have been meaning to buy a can of compressed air and blow out the inside of the case, but i can't drive (legally, at least 
so that hasn't yet happened.
my computer DOES have a seperate pci-e gpu, and i HAVE overclocked it a little bit using ati tool (from 450 MHz core and 290[580]MHz memory to 530 MHz core and 300[600] MHz memory). it's an ati radeon x600xt, and it doubles the memory speed when running a 3d app. however, it is stable and artifact free; ati tool lets you scan for artifacts, and i ran it all night with no errors.
thanks for your help

Your picture doesn't show the area
by Ray Harinec - 2/12/06 3:03 PM In reply to: re: by nathanpsz2of interest. It is blocked by the structure of the case. I can't see if there is part of the PS in the area blocked by the structure.
I checked the hp site and in the section of step by step to replace memory or, First step shows rear view, I still can't tell. In the rear view I see the PS seeming to be rectangular and using a mounting pattern for the four screws to be similar to a standard ATX, HOWEVER I also see an area above the PS that might be a rectangular cut out that would allow the top section of the supply to fit through.
Easiest way would be to do a search in google for a power supply for the model of your system and then look at the pictures of the supply they offer.
Here's a link to a forum
by Ray Harinec - 2/12/06 3:30 PM In reply to: re: by nathanpsz2where a guy said that he put in an Antec 550. It was not the main point of his post, but it seems to indicate that you can use a standard ATX supply. Get the newer type that has a combintion 20/24 pin connector to be certain that it can be used in your system. The standard replacement seems to show a 24 pin connector though.
A 400 watt or 425 watt should be a good replacement.
Keep in mind that there is no longer a "standard" ATX because now you may want SATA connectors, the 6 pin connectors, the 8 pin etc which one needs when one goes to these super video cards.

This one look good?

Looks good to me.
by Ray Harinec - 2/12/06 5:15 PM In reply to: This one look good? by nathanpsz2Might be a slight overkill if you are short of money. But you are thinking right.
Is it good enough to...
by nathanpsz2 - 2/12/06 6:02 PM In reply to: Looks good to me. by Ray HarinecUpgrade the gfx card to a 7800GT?
Fixed the problem
by nathanpsz2 - 2/27/06 12:36 PM In reply to: Looks good to me. by Ray HarinecI didn't realize that the case is venting through the side, and I had it too close to the wall. I moved it away from the wall, and moved the sound card away from the video card. This fixed the problem.
LOL...

Power supply too low
by fiqqer - 2/27/06 3:28 PM In reply to: Computer shuts off for no reason by nathanpsz2300 watts is very low for a pentium 4 and separate graphics card - go for 450 minimum possibly 550. You could be damaging the components by having to little power. Every device needs a bit of power - those usb ports also need a bit. That is first point of call. 2nd is is the computer going into sleep mode/
Would this work?

I'm also considering buying a new case to improve the airflow.
