Computer Output Issue.





cr3ativ3
Hey, my mom went to go on our computer this morning I was still sleeping... (had to be woken Confused ), anyways the computer wouldn't turn on so I looked to see if the PSU was turned on and wether the computer's power cable was plugged in on either side, I use a power bar. The power bar works because other electronics will turn on using it.

So I took out my computer un hooked all external hardware and opened it up, looking through it to see if there was any problems.. I saw nothing wrong all though 7-8 years of never being opened, dust was pretty bad.. I meen centimeters of it Sad. Then it occured to me to try a differen't power cable just incase for some reason the one I was using blew or something. So I went to my sister's house to get her computer's power cable, so I tried it the computer would stay on for 5 seconds before turning off using her's it was able to be turned on 3 times. Then it stopped turning on using it. Then I remembered that my monitor uses the same type of cable so I tried using the monitor's cable and it has been turning on using it.

The problem is I am not getting any output from the computer like I can use the cd drive it opens and closes when I press the open button but when its on, the monitor won't display anything(it's plugged in) I was able to find another power cable for my monitor, the monitor just stays in stand by mode when the computer is on or off. My usb mouse when it's plugged in, it isn't recieving any "stuff", same with any other external hardware.

One more thing I took out the ram disk when I was checking for problems in the computer, to show my mom what it looked like. I was having problems getting it back in, it wasn't snapping in easy I could always get one of the ends of the ram disk to lock in but the other wouldn't I finally got both ends in properly. Could this have anything to do with the lack of output? The screen won't display anything this includes some of the start up information that display's before it shows the ram loading, so I don't think the ram is the problem with the monitor.

Also internal hardware in the computer works like the fans and hard drive and the cd drive well not sure about the hard drive I am not sure what it sounds like but I know the cd drive works and the fans. Also right after opening it I dusted off the inside with an ordinary dusting cloth. It might have been a swiffer cloth(don't think so though).

If you need computer specs feel free to ask I'll look for some if anyone needs them but what I can tell you right now is it has:
40 GB HARD DRIVE
512 MB RAM
WINDOWS XP HOME SP2
1 CD RW DRIVE
1 FLOPPY DRIVE
6 USB PORTS
1 KEYBOARD PORT
1 MOUSE PORT
1 MONITOR PORT
AUDIO PORTS
AND ONE OLD PRINTER PORT I THINK IT IS IONO WHAT IT IS FOR.

I am not a computer nooby. I just deal more with software rather then hardware. My time is running out on this library computer.... So I need to finish up so also if I hadn't mentioned it fried two power cables and trust me their friend they won't work on other computers. The only difference between the cables that were fried and the cable that works is the color of the wire I meen the casing the fried ones are black and the one that's working is white.

I also can't afford and buy new hardware for the computer unless it is like under $20 so I really need to try to fix this myself. Parts of the mother board work fine cause one of the fans in the computer get's it's power from the mother board.

I may edit this later I got 2 min's till I get kicked off this comp.

[edit]Also when I turn on the computer it meeps three times(which it didn't do when it worked), there is one little speaker I found on the bottom of the computer on the inside so I unplugged it from the mother board and turned the computer on to see if it meeped again but it still did and I can't find this hidden speaker =\. No I do not have the external speakers plugged into the computer, when I do have the speakers plugged in and the computer is turned on the speakers make this wierd humming noise...[/edit]

Thank You!

If it beeps when you boot then it means the BIOS has found that there is something important missing. Now, this could be something simple like the keyboard but it given the symptoms it could be anything.

If it had failed to turn on then I'd assume that somewhere your hardware has failed. I'd investigate in this order:
1.) Motherboard
2.) PSU
3.) Graphics card
4.) Hard Disk

In all likelihood you motherboard is probably hosed. You're computer is old an capacitors start to blow after a time. I'd clean off all the dust on everything just to see if it works - it might just have shorted out and be ok.

K, I checked all of those I didn't notice anything wrong. What should I be looking for anyways, and it never beeped before now even when I didn't have any external hardware plugged in to it.

Also what could cause the computer to kill a power cable? Do you need to use a special of dusting the inside's off could a normal dusting cloth could it cause some static electricity damage? If so well that might be part of the problem.

I hope I can get this fixed without buying a new computer because, I do coding jobs for people so I really need to get on a computer and the local public computer center is the library with a 2 hour a day limit.

Thanks!

Why not check the beep code magainst those here: http://www.computerhope.com/beep.htm or here: http://www.pchell.com/hardware/beepcodes.shtml

The beeps mean something and they can usually help you narrow down the problem. Good luck.

K thanks, I'll try matching them up. I just need to go out and get a new monitor cable to use with it so it doesn't blow the cable.

Just, a quick thought - are you sure that it's actually the cable that's broken and not just the fuse that has blown on the plug?

If you're computer has shorted out somewhere or has an electrical fault then this is the simplest explanation for your cables not working any more!

Well, see I am not sure if it is the power bar that is blowing the wires when it's plugged into the computer and I turn it on, or if it's the computer blowing them. Because the black wires were being blown when I plugged them into the power bar and turn the computer on. I tried using other plugs in the power bar same problem when I decided to use the monitor cable I plugged it directly into the wall and the wire was fine I am not sure if was the power bar then.. But I plugged the monitor into the same spot on the power bar and turned it on and it didn't have the wire blow so...

I then tested the black wires in the wall outlet and hooked them up to the monitor but the monitor wouldn't turn so it should have which makes me think the wires are messed rather then the computer.

Thanks.

Are you sure that the power (black) cords are being blown out? If so, that is very strange and would think that you would have some serious burning going on which would be recognizable by seeing smoke or smelling burnt wire coating.

Otherwise, I would recommend testing a power cable that "burned out" while connected to your computer. You could simply just plug it into your monitor and see that it at least powers on with a display or standby.

DON"T USE CLOTHS FOR DUSTING COMPONENTS. I would recommend either vacuuming or blowing out the dust without too much air pressure. Canned air works just fine. I have restored several Desktop systems to normal operating simply by cleaning out dust from the system, which most frequently causes processors to overheat. Check to see if your heat sink and processor fan are clear of dust, as well as most other components and fans.

If you post your system model, I can help with your "meep" codes or beep codes.

This is a good sign that you are having ground issues. Make sure that all of your power cables are well grounded.

Below is a picture of the Ad in the newspaper for my computer and a picture of I guess the some computer info and the setup and design of my computer.

Also the cables I did test in the monitor and the monitor won't turn on using them the black cable you see in the one video is one that one of my friend let me borrow for now.

Thank You!
