Help!!! Dimension 5100-wont power up after usb surge error

I recently moved and hooked up the comp. Plugged everything in while it was off. After booting, my friend asked about the printer. I blindly went to plug it in. I don't know if I touched a wrong port or something because I was reaching back behind the computer instead of visually inserting it. Noticing there was not any more USB ports I went to the front. She also tried as well saying it was plugged in back there. At this point the comp. was turned on. Then I got an error of a USB port hub overload (something along them lines)  I then shut down the comp. the proper way. Since then the comp won’t power up. I get the blinking amber LED in front, steady green on the mother board. I went out and bought a new power supply and have the same results. 

 

What does all this mean?

What does the solid green on the motherboard mean?

What are my next options?

 

I saw that those motherboards are limited and not easily replaceable with anything other than a dell.

 

Please help...

Thanks Tom

I would first check for physical damage to the USB ports.  Some people with a similar problem have seen shorting pins, "unshorted" them and got the machine working again.

Thanks.

I will give that a try but what does the the errors and lights exacly mean. I have read on it. I know the amber light not the steady green on the MB? Will that come on even if the MB is bad? And if that does not work where do I go from there?

It means there is some kind of power problem.  The PSU could be bad (but you checked that already) or there is something causing a power problem (e.g. a short on the motherboard, a drive or a USB connector/device).

I had a similar problem, and I've found a work-around, but not a complete solution: 

After I turn off my Dell E510, I cannot turn it on; the front power light flashes amber.

- When I disconnect all USB devices, and remove and reinstall the CMOS 3V battery, I can restart the computer provided that no USB ports are in use.

- Once the computer is restarted this way, I can plug in my USB devices and the computer works fine. BUT if I turn off the computer, the amber light resumes and computer fails to start again.

- It makes no difference which USB ports I use- front or back.

- I CAN do a soft reboot without problem.

- I've checked the USB ports to see if any prongs are bent, but all of them look normal.  I've removed all the dust from the interior, and there are no signs of any shorts that I can identify.

Well so far nothing has worked. How do I test the MB? Anyone know of a good replacement that isnt 300$?
Any other sugestions?

Basically, you have to determine the problem by process of elimination.  If nothing else is the problem, then it must be the motherboard.

 

You should be able to get one for less than $300 ($400 buys you a modern system with 20" monitor).  Google for it and/or check eBay.  I would think you could get a board like that pretty cheap because it doesn't support the Core processors.

I know exactly what you mean by process of elimination. Though thats where I'm lost. How do I go about that to get the end result I need. I guess I have eliminated the power supply. Though I get the same result with the old one as I do with the brand new one?

Any chance you could step by step me through it. I hope I'm not asking for to much....

And I dont know if you know the MB I have its a TD217 and its USB's are part of the MB.

I would try disconnecting things until all I have is the PSU and motherboard (without CPU ... I would pull this out last).  If the power light is still blinking amber and you tried a good PSU, then I would say it must be the motherboard.

Re: Help!!! Dimension 5100-wont power up after usb surge error

Did you try my trick with popping out the CMOS, and then putting it back in, and starting with all USBs disconnected?

Admitttedly not a permanent solution, but I've been able to keep up and running that way as long as I don't turn off the computer....
