GA-X58A-UD3R, no power..

Re: GA-X58A-UD3R, no power..

I am waiting for the replacement motherboard to arrive. It is delicate work to straighten pins, and the shop wanted $200 to do it, I told him I could almost buy a new motherboard for that price. He told me
that he diagnosed this situation by taking the cpu out of the motherboard. He said the system then had power, at least to the fans. I tried to duplicate this test when I got home, but all I got was the same old blue blinking lights (cmos clear and power button). Has anyone tried this test? I'm hoping that I don't have to replace the cpu too. They didn't have an extra cpu this new (i7) to swap out with. If there is such a test (no cpu), I'm thinking of trying it on the new motherboard before installing the cpu. I want to see a fan work, any fan.

Re: GA-X58A-UD3R, no power..

i dont think it would affect your cpu,you can try starting it without but i dont know if anything will spin up as i havnt tried it,maybe all the mb led's will light up

Re: GA-X58A-UD3R, no power..

Just RMA the board to Gigabyte, no need to pay $200 to him!!

If there is no CPU installed, nothing will work. He is just making things up and besides, for any fan on the motherboard to even spin the system has to start anyhow.

And I'm sure your CPU is fine, as long as it was not DOA when you got it.

Re: GA-X58A-UD3R, no power..

Eureka, It Lives!! I had 6 gigs of ram installed and it recognized all of it, also my Geforce 9600 Verto(for video editing and CS5) My monitor lit up and I could go into Bios Setup. The POST screen went by so fast I couldn't tell my Bios version, I didn't see it in Bios setup yet. I think I got those little two strand wires connected properly, the power switch and reset work. Thanks for your support, especially letting me know the cpu was probably good. I'm going to try to dual boot Windows 7 and Snow Leopard and that will be fun compared to having "no power" Also the psu short the green wire/black wire test was good advice. I have a Cooler Master V8 but the stock fan is installed.

Nice to hear you now have a working system! To check BIOS version press F9 in the MAIN page of the BIOS.

So, how did you end up getting it fixed, did they switch out boards for you or did someone fix your pins?

Re: GA-X58A-UD3R, no power..

I have the GA-X58A-UD3R, and I was watching TV and suddenly my headphones starting beeping for no reason. I noticed on the back of the case that the CMOS Reset light was blinking in sync with the beeping on my headphones. Now OBVIOUSLY this isn't a brand new computer, and it worked for 14 months, and stopped working when the computer was turned off. The PSU was obviously on in the back, but the computer itself was powered off. Now I removed all components and that did not solve the blinking light problem at all.

I then removed the large motherboard power plug, and the CMOS Light stopped blinking, as I assumed it would, without getting power from the PSU. Now this happened literally 27 minutes AFTER tech support closed for the weekend, for the company I got the computer from, so I kinda wanna get my computer back before waiting 3 days for the tech support people to tell me to do the same things I have already tried.

Since it was working fine for so long, and it died for no apparent reason while turned off, what are the possibilities here? Power Surge that somehow got past the surge protector, frying the PSU, causing it to behave at less than 100%? Same Cause, but instead of the PSU, the MB perhaps? If not a surge, which I doubt since I was watching TV and it is hooked into the same surge protector and I saw no sign of problems, then what could have happened when it is just sitting there turned off? It has me super stumped and I have built, and repaired my share of computers. I'm a retired Electronics Technician, and so far I have no found any shorts, bent pins or any problems that are readily visible.

I cannot turn the computer on by shorting out the power button pins, so I assume the power button is fine. The RAM, Video Card, LAN Card and Sound Cards all check out on another system. Any help would be greatly appreciated on this. I am down to PSU, MB(and/or Components of the MB) or possibly the CPU I suppose.

Re: GA-X58A-UD3R, no power..

try removing mb battery for 30 minutes or even leave out overnight to fully clear the cmos,try with only one ram stick in any of the white slots,test each white slot one at a time,could try and borrow another psu to try? try pulling out the fron panel audio and usb connectors from mb and try booting up,could be front panel problem?

Re: GA-X58A-UD3R, no power..

I pulled out all components, including ram, and tried each ram individually. I powered the PSU while unplugged from the MB by shorting the power pins on the plug. It powered the front fan control, all the fan and such. I tried pulling the USB connectors from the MB that I could get too, but I didn't think of it until after I put the video card back and it covers a few.

The front panel Audio and USB connectors I will try first, then I will remove the CMOS battery since I will have the Video Card out and will be able to get to it at that time. I don't have onboard video, but my computer will do something different if it is working, but has no Video card inserted correct? I really find it hard to believe it is any of the cards, ram or HDD's, as they have worked for over a year flawlessly. The USB connection sounds very feasible as they do get a lot of connecting and disconnecting of headphones, mouse and whatnot. Something completely retarded and probably a 1 in Million thing, but still.

Has ANYONE ever had a problem like this when the computer was off, and behaved like a new MB that has a problem with the PSU or short?

Thank you for the reply and help. I will let you know of the outcome of them.

Re: GA-X58A-UD3R, no power..

You were right, F_USB 1 connector disconnected and the CMOS Reset Light stays on steady and the computer turns on. Didn't need to remove the CMOS or anything, just unplugged all those USB connectors on the bottom of the board and found it was #1. The others seem to be fine. I can't really see the plug, as there is very little give, but the MB connection looks fine. I am thinking there was some overload on it.

Thank you again for the help, I was going nuts looking at everything else, and it was something simple as that one connector I didn't even think about until you mentioned it.

Re: GA-X58A-UD3R, no power..

It's probably a bad or faulty Usb lead from your cases front panel,you might be able to buy a replacement lead or rma/replace the case,if its not essential you can just leave it unplugged from your mb,I don't think its the mb Usb header but the case Usb lead,they are pretty poorly made on some cases

Glad you found out what it was though

Re: GA-X58A-UD3R, no power..

Thanks So much for this Thread.

I also had the blinking clr cmos issue reading that it meant a PS was not compatible saved my much tear down time.

Replaced the PS and my PC fired right up. I was about to disassemble and start over. ( My PS was brand new so i thought it would be the last issue)

Many thanks again

Re: GA-X58A-UD3R, no power..

You can still get a faulty or just incompatible psu even if its a top of the range make/model,so its always best to borrow and test with another if you can,in the case of the op,it turned out to be a faulty Usb front panel cable,glad you found the thread
