Why wont anything I plug into my computer work?

Question

The keyboard, mouse, and Monitor that are hooked up to my computer dont turn on but they are 100% working. All connections are made correct and the lights and fans are spinning. The hard drive turns on, the RAM works, and the Cd Drive opens.

Simply put ... ANything i plug into the back wont work or turn on. My mother board is this : http://www.newegg.com/Product/Product.as...

Not sure If there could be a hidden jumper setting or if its a bad motherboard completely or whats wrong with it. But I cant see anything on screen and the periphs wont work. yes i connected everything ... And yes this starts up, the hard drive is running and the cd drive will open and run ... just no screen and no key/mouse ... dunno why

Heres some completely USELESS comments:
Check Connections
Flash Motherboard
Have you installed the OS? ( no moron, cant see the screen ...)
Do your mouse,keyboard,monitor work? ( READ!!!)

Please do not attempt to answer this question unless you've read my problem.

As you may be able to tell, im frustrated and annoyed with poor responses that dont even listen to what I say. Ive spent alot of money building this computer and I need it to work or need to know if I send in an RMA. Ive asked this question 4 times now and get the same mediocre answers. Does anyone REALLY know?

I have 4 computers in my house ... The one I built is not even for me or my family ... Im trying to sell it .... Dont answer my question with another question ...

Answer 1

First unplug power and check that your cards (ram, video etc) are firmly in place. Did you put heat sync paste on the cpu? Check that you have connected the 4 pin power plug to the board. (easily missed, as not used on earlier systems) Unfortunately your link does not work. Try disconnecting the power plugs and shorting the clr_cmos pins. If this does not help, as a last resort remove the cpu and visibly check that the pins are straight. On a recent Intel cpu install I found a few of the pins in the socket were damaged. Stray dropped screws under the motherboard can do this also.

Does your iPod indicate that it's plugged in? Is the green charging bar coming up on it or the little lightning bolt on the power bar icon in the upper, right corner? That's the first thing to check. Try rebooting the iPod, rebooting the computer, un-installing then re-installing iTunes, etc. I know those are pains in the neck, I've been through it all. But it can be worthwhile. Also, check to make sure your device is appearing on your computer. On PC you can do this by going to My Computer and your device should be there under "Devices With Removable Storage", on a Mac it should just appear on your desktop or if you go to Finder and go to your Mac User, it should appear as an icon there. If it's not there, then you know it's the computer's issue and you could work around that accordingly. And, if there's no indicator on your iTouch that it knows it's plugged in, it could be your iPod's problem. Try plugging it into anything else with a USB port to see if it recognizes those. That could help identify what electronic is the problem. Hope this helps! Happens to me a lot, ik it's not fun!

Make sure you have two power cables plugged into your mobo, I know it sounds simple but I ran into a similar problem (I plugged in the huge rectangle power cable, but not the little square one.)

For me, my problem was everything would turn on for a second then shut down. Also, I didn't relise that (stupid me), the motherboard had to be rasied a bit so the back don't contact the metal (of the case). Sorry that's my only experiences but it's better then "Make sure you device manager..." lol.

Good luck. Try a barebone setup: no graphics card, 1 stick of ram, no sound card, cd rom drive, hdd, etc. if it it's fine then, maybe - well maybe the graphics card to see :)

Does your mobo give beep codes?

p.s. gave everyone a low rating except the guy above me, which that may be your only recourse.

D.)PERIPHERAL WON'T WORK.

Peripherals are any devices that are connected to the motherboard, including I/O boards, RS232/UART devices (including mice and modems), floppies and fixed-disks, video cards, etc. On modern boards, many peripherals are integrated into the motherboard, meaning, if one peripheral fails, effectually the motherboard has to be replaced.* On older boards, peripherals were added via daughter boards.

*some MB CMOS's allow for disabling on-board devices, which may be an option for not replacing the motherboard -- though, in practicality, some peripheral boards can cost as much, if not more, than the motherboard. Also, failure of on-board devices may signal a cascading failure to other components.
1. New peripheral?
a) Check the MB BIOS documentation/setup to ensure that the BIOS supports the device and that the MB is correctly configured for the device.
(Note>> when in doubt, reset CMOS to DEFAULT VALUES. These are ) (optimized for the most generalized settings that avoid some of) (the conflicts that result from improper 'tweaking'. )
b) Check cable attachments & orientation (don't just look, reattach!)
c) If that doesn't work, double-check jumper/PnP (including software and/or MB BIOS set) settings on the device.
d) If that doesn't work, try another peripheral of same brand & model that is known to work.
e) If the swap peripheral works, the original peripheral is most likely the problem. (You can verify this by testing the non-working peripheral on a test MB of the same make & bios.)
f) If the swap periphal doesn't on the MB, verify the functionality of the first peripheral on a test machine. If the first peripheral works on another machine AND IF the set-up of the motherboard BIOS is verified AND IF all potentially conflicting peripherals have been removed OR verified to not be in conflict, the motherboard is suspect. (However, see #D below.)
g) At this point, recheck MB or BIOS documentation to see if there are known bugs with the peripheral AND to verify any MB or peripheral jumper settings that are necessary for the particular peripheral to work. Also, try a different peripheral of the same kind but a different make to see if it works. If it does not, swap the motherboard. (However, see #D below.)

Answer 4

Wow...the best way I can answer your question is to tell you this..the spark you see on the end of your finger when you have static is 30,000 volts! Your computer uses between 3 and 12 volts! so if you have static and touch the motherboard for example..? (did you wear any anti static device) no wonder your are frustrated with the answers you are getting..because we can only guess. Put a multi meter over your system or give to to a professional.
When you boot a pc it it goes through about 12 steps..looking for items in a certain order and it sounds like it is finding items as you say like hard drive, etc (don't know how you determined the ram it working when you are not ramming anything) but anyway, it sounds like your CMOS or peripherals bus.

Answer 5

I know with the HP computer I bought there was a base OS already on it, if you are able to open the cd drive I'd try putting an OS disk in there to see if that will start up the computer, other than that I don't think there is much you can do, is this a new computer or did you have to take the os off? If it is new I would call Dell or whoever to see if they might be able to help you out, I hope this helps out some, good luck

Answer 6

Hi. Zack. Try not to get frustrated. The link to Newegg did not work for me but the brand and model wouldn't help any way. There is no jumper to make the interface devices work. They just should. If you can get an RMA from Newegg (they are usually pretty good about this) I would return the board. PIA I know, but it sounds like you did all the right things. Stuff happens.

Answer 7

Sounds like possible something in the tower is broken or lose. Go one craigs list and find for your area a computer repair person. Computers are tricky one small inoccent thing can seem like a huge issue. GL

Answer 8

Did you go to that system's BIOS?
Usually you get there during "BOOT-UP" by continually pressing the "DELETE" key until the BIOS panel comes up. In there you will find switches (electronic) to turn on USB ports and other electronics in your computer.

With your attitude, you are lucky you got this many people to help you! Your attitude sucks big time.
Maybe this is a project you should have not started and let the pro's have done it for you. Armature.

Answer 9

Well my first question is, are there any yellow or red flags in your device manager?
if so, go to that device and try rolling back the driver(S) if available.

Obviously there is power to the ports if you are getting power to the devices.



Maybe post back with your results?

Answer 10

Is there software that comes with the things you are plugging in. You might have to download it before anything will work.
