PC does not responde to boot
-
The drives were not spinning. It feel like all the input devices are disable. When I unplug it, it still has keyborad,mouse and phone set plugged in. The green light gets dimmer and dimmer and goes off after an hour or so. I think this is probably the feature to pretect power out but might turn out screw it up for me. Thanks for the replies, any other thoguths are greatly appreciated,
STOP!! Before you follow Matrix's advice about putting a suspected bad power supply into a good machine... Think about it. If the voltages and levels comming out of a PS are bad, what are the chances that they could blow anything you plug that PS into?? Pretty good... You NEVER put a suspected bad PS into a known good machine. You always replace a suspected bad PS with a known good PS and see what happens. If the PS is bad, you won't blow a good motherboard. If the motherboard, or something else, is bad, the good PS will protect itself from an overload and shut itself off.

Well, his description of the problem amounted to "turn it on and nothing happens". After doing this crap for over 21 years, I can tell you that a bad power supply, bad BIOS, bad motherboard, AND a bad CPU are the possibilities. BTW, putting a suspected bad power supply into a known good PC is a bad idea. If the power supply blew the motherboard, you'll just potentially end up blowing another motherboard. Testing the voltages comming off the power supply is the best option, but in the absense of a voltage meter, replacing the power supply with a known good power supply is the next best option.

Good point, I never thought of that.

Thanks, I will get a good PS and see how it goes. just to get my knowledge a bit more on this. The reset button seems to connect to the motherboard, when it is pressed and hold, a signal is sent to the motherboard to resstart the system. Am I right? If I am right,this could explain there is a possibility that the motherboard is bad. But the DVD button is not working as well, the DVD looks like was connected to PS directly, does it lead to that most likely is the PS?

You could check for the presence of PWR_OK after starting up the PS (see http://www.quepublishing.com/articles/article.asp?p=31105&seqNum=2&rl=1[^]

More or less. Both the reset and power buttons are soft switches whose functions are controlled via the mobo. If the mobo isn't properly starting the PSU up that could be the problem. You can "jump start" an ATX PSU by using a paperclip to short the green wire to one of the black ones (this is what the mobo does in response to your pressing the power button). If all your drives spin up normally and will open the PSU is probably innocent.

Alright, I change to a PS I know is good and "jump start" it The CD lights up and responds. It does not open up so it's not quite working nornally. The old PS does not do that so I guess the old PS is bad. Glad to have this at lease one step forward. But.... With the new good PS, the system is still dead. much like before. can you suggest what to do next? Thanks

Diconnect power to all the drives and everything else, except the motherboard. Power it up. If still nothing happens, then you've probably got a bad motherboard too.

You're both wrong - It's obviously the internally adjustable throwout deframulation transistor.

But since I know nothing of his surface-mount soldering skills, I didn't want to walk him through replacing it. He could do more harm than good, especially if he gets the streams crossed! Oh God - then what?? :laugh:

Hi, I need some help here. I have a Compaq Pasario running celeron with XP professional. I was away for 5 days and my PC has been in stanby mode. After I came back, my PC does not responde to any actions - keystrokes,reboot,unplug. The screen is out and the light is in orange. It does not take key strokes. The light on the pc itself is blinking green, I press and hold the power button(cold boot) and it still does not do any thing. I unplug the power cable wait for hours until the blinking green light goes away and plug the cable back again, the green light comes back and still nothing happens, Anyone can give me some help what seems to be happening and how can I do about it? Thanks,
Try placing the boot a little more to the left (or right) of the computer. Maybe it's too close to respond to it. Check the boot's antenna. If you have a heel-mounted antenna, that might be the problem.
