PC Don't star

my PC don't start, when I press de power button nothing happen, but in the motherboard there's a ligth on, please help me.

 

can you give us some more info? did you just build the computer? did the computer die and then this started happening? is it a new computer? have you ever been able to start the computer? anything weird happen before the problem started happening?

details man details....

 

Welcome to MG.

On the limited information you've given my first thought would be the Power Supply Unit (PSU) has failed.

 

With limited information, and if this is just out of the blue, we can run you through the tests, but the possibility that the power supply unit has died is there.
I suggest that you turn it off, and check all the leads are properly connecting , on the motherboard- be sure to earth yourself- with an antistatic strap, if possible, otherwise before switching off touch the chassis of the computer, before anything else- if next to a radiator, hold that before touching inside the computer.
Then look at the small leads from the power button- do not remove, unless you hve a manual to know where they go back-just press gently to be sure they have not loosened.
.
Then replace power cod, and restart.
If nothing happens, then come back, and tell us as much as you can about your pc- and if you are using XP, 200. ME, 98SE.

 

REMOVE YOUR MEMORY STICKS AND SEE IF THAT WILL DO IT, ALSO CHECK AND MAKE SURE YOUR PROCESSOR
IS SEATED RIGHT

 

confused Removing the memory would cause the PC to fail POST and not boot but if the PC never gets that far then as I said earlier and baklogic reiterated then its probably the PSU.

 

Hello, thanks for all the help, but still not start, I have E-Machine T2824 WinXP and I bought a PSU tester and is good , but the PC won't start and the ligth on the motherboard is on when I plug the cable on the PSU, I took the everything out and put it back on and nothing happen, please I need Help
Thank's for everything...

 

To give more help, we need more information from you.
CPU,PSU,Ram, MOTHERBOARD, and what you last did with the computer, before this happened.
I have one suggestion to make without more information- But it's a bit of working in the dark fiddling, not good practice---look for pw or similar on the little leads from the front panel to the motherboard- sometimes it is a single, sometimes two ,or ,three hole flat connector, and is usually by the bottom right of the motherboard.Look for sw, or pw on the lead.
If you can find this, remove the lead/leads (+ and _, if two single leads.
Remember where you got them(do a little drawing)
There are two things you can do to check if it is the power switch.
1/ YOU CAN BRIDGE THESE CONNECTIONS WITH A SMALL PLUG OF THE BACK OF AN OLD HARD DRIVE/CD ROM (CALLED A JUMPER)
2/ YOU CAN TEMPORARILY PUT THE RESET BUTTON WIRES ON THEM.
Then, next to the power button leads, there will be another similar with reset, or rst,or, similar on these- come back and let us know, then it is possible to put these in the place of the power button leads, and then try stating, with the reset button.

 

Be sure to replace the leads, but especially to remove that little jumper, after the test, UNPLUG FROM MAINS BEFORE GOING INSIDE THE PC, AND TAKE ANTISTATIC PRECAUTIONS.

 

How do I know if the Motherboard is not good confused

 

The fact that you you've tested the PSU outputs ( I assume your tester does test all the outputs?) then you will need to disconnect everything except the Hard Drive and see if it boots then. If not will it boot from floppy (with the HD disconnected) The light on the mobo is generally telling you that one of the 5V lines is OK but that's all.

 

Let's start at the beginning-
If your Psu, Ram is o.k, (as someone mentioned earlier) then you would get a beep (post) - Start by disconnecting the hard drive,cd/dvd rom(s)
If you have a video card remove it.If you have any PCI CARDS IN THE SLOTS- REMOVE THEM.
Then , start the machine with only one stick of ram in a slot, nothing else.
If the machine does nothing, try swapping a ram stick, if you have one, and try again.
If nothing again, test your ram in another machine .You need to knoe the ram is good (working)
If the psu, and ram are working, you should get a beep, or beeps if it warns of no graphics card.
If your ram is tested good, and you do not get a beep, then it could be the psu, the cpu, or , the motherboard that has failed- most likely the psu.

Sorry Yargwel, crossed posts, but on same lines.

Read Yargwel's input together with this one.

 

And just as a further point, when you said in your original post that nothing happened when you pressed the power switch, do you mean no fans spinning up, nothing shown on the monitor, no POST beeps or do you just mean it didn't boot? I'm asking because the more information you can give us the quicker we can pin down your problem.

Until then continue with the advice given to you by myself and baklogic.

 

Your motherboard ?

Socket 478
Max 2gb DDR RAM
On board graphics ?
T2824 Intel D845GVSR Intel® Celeron® D 325 2.53 GHz

This is what's happening to PC
Suspend to RAM (Instantly Available PC Technology)
CAUTION
For Instantly Available PC technology, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current. Failure to provide adequate standby current when
using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM)
sleep state. While in the S3 sleep state, the computer will appear to be off. When signaled by a
wake-up device or event, the system quickly returns to its last known awake state.
The desktop board’s standby power indicator, shown in Figure 2, is lit when there is standby power
to the system. This includes the memory modules and PCI bus connectors, even when the
computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber.
OM16273
Figure 2. Location of Standby Power Indicator
CAUTION
Power supplies used with this desktop board must be able to provide enough standby current to
support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby
current necessary to support multiple wake events from the PCI and/or USB buses exceeds power
supply capacity, the desktop board may lose register settings stored in memory.
What should I do?

 

I suggest that you unplug the power supply, and move the motherboard jumper from the two pins that it is on at the moment (usually 1 and 2 ) and putting it on 2 and three, for about 30 seconds, or, so, (usually found at the bottom right lower end of the motherboard )--look in the manual, if you cannot find it.
Or, remove the cmos battery , for a few minutes, then replace it. This shoild reset the Bios defaults, and enable you to start.- You may have to do this over 24 hours, if it does not work after this, but you can try it, again for half an hour, before the 24 hour.
It would seem that you have the computer hibernation(sleep) mode selected, in Windows, and this does sometimes cause problems with restarting, as explained in your last post, from your - I think I came across this in XP Professional, - anyway, that is my first suggestion.
I also wonder if your test of the psu found +5v on that line, but as the computer suspends to ram, in hibernation, the settings being held in ram, for quick startup at the wiggle of your mouse, or keyboard, the low voltage from the psu, meant it has frozen there.
By resetting your motherboard Bios, this could solve it.
Next time you are in Windows, I suggest you disable hibernation -or, put to never.
It is also be worth upgrading that PSU.

 

When you get back into startup, go straight to your Bios, and untick suspend to ram, and see if that saves you a psu.

Re: PC Don't start

Vraj74,

Is this a new question? If it is it, you should start your own thread then we know we know how far we've progressed for any particular problem.
