pantzdown Posted October 30, 2011 Share Posted October 30, 2011 Hello everyone, i just got my desktop delivered to me in the UK, it was shipped over from the US, it was built in the US. it was packed securely, no damage to the box it was shipped in or damage to the desktop it self, i have a corsair 750W in it, after powering it up both the power light and reset light cam on and stayed on there was no POST. so i unplugged the PC, opened it up, and replaced the CR2032 battery (thinking it might have drained itself) re started the PC, and the same thing happened, no POST. i then opened it again took out the memory(corsair)took out the video card(GT X 260), unplugged the HD and CDR and DVD drives only to have no POST and not even a beep code of any kind( PC speaker is there and plugged in, i am guessing that the motherboard or PSU is not working, i dont have any other parts to be able to test with, both the motherboard and PSU are still in warranty, what should i try next to deterime what is the issue ? thanks in advance Link to comment Share on other sites More sharing options...
Synthohol Posted October 30, 2011 Share Posted October 30, 2011 is there a 110v/220v switch on the back of the PSU? we have different voltages across the pond. it may be auto switching but im not certain. you could give it the paperclip test outside the case.

pantzdown Posted October 30, 2011 Author Share Posted October 30, 2011 It is a Corsair 750W PSU which i understand from this forum is an auto switching power suppply, i am using an adapter http://www.amazon.co.uk/Travel-Adaptor-Plug-Worldwide-European/dp/B000P0FIUM/ref=dp_cp_ob_ce_title_1 to plug the US PC cable into the UK wall outlet.

Synthohol Posted October 30, 2011 Share Posted October 30, 2011 hmm you may try one of these http://www.amazon.co.uk/Belkin-European-Mains-Cable-Style/dp/B000FO6I7U/ref=sr_1_19?s=computers&ie=UTF8&qid=1319990628&sr=1-19 instead. but in the meantime, try the paperclip test to see if the PSU will power a fan. http://forum.corsair.com/v3/showthread.php?t=63991 Link to comment Share on other sites More sharing options...
pantzdown Posted October 30, 2011 Author Share Posted October 30, 2011 i have one of those , i just thought i would use the adapter to be on the safe side, since it worked with my US dell laptop, i have also done the paper clip test it powers a fan, so i am guessing the power supply is ok, which now leaves the MB or CPU ? Thanks in advace Link to comment Share on other sites More sharing options...
Synthohol Posted October 30, 2011 Share Posted October 30, 2011 use the jumper on the MB to clear the cmos and try again. are there any lights on the MB when its plugged in? try jumping the power switch header on the MB manually in case the case switch is bonkers. if all that fails i would suggest removing the board from the case and testing it on a table on newspaper. i hope the X-RAY at the airport didnt damage anything. only because im brave i would try the paperclip test with everything plugged in just long enough to see if it posts.

pantzdown Posted October 30, 2011 Author Share Posted October 30, 2011 use the jumper on the MB to clear the cmos and try again. did that ... same thing. are there any lights on the MB when its plugged in? No, i dont see any lights that come on, on the MB try jumping the power switch header on the MB manually in case the case switch is bonkers. did that ... same thing. if all that fails i would suggest removing the board from the case and testing it on a table on newspaper. that was going to be my next step, but that will ave to wait until Tuesday. i hope the X-RAY at the airport didnt damage anything. why and what would the Xray damage ?. only because im brave i would try the paperclip test with everything plugged in just long enough to see if it posts haha i am not that brave right now .. lol Link to comment Share on other sites More sharing options...
Synthohol Posted October 30, 2011 Share Posted October 30, 2011 is the 8 pin power cable plugged in also? also "gigabyte" is very vague in your system specs, please add the model so i can try to help you further. Link to comment Share on other sites More sharing options...
pantzdown Posted October 30, 2011 Author Share Posted October 30, 2011 Yes the 8 pin cable is plugged in, i unplugged it an re plugged it back in, this is not a new build, i was a working system before it was shipped, yes i know things can happen in shipping, i just thought it should have made it with very little damage, and at least POST here is my MB http://uk.gigabyte.com/products/product-page.aspx?pid=3108#ov Link to comment Share on other sites More sharing options...
Synthohol Posted October 30, 2011 Share Posted October 30, 2011 unplug power to the MB and try the paperclip test. see if anything spins up. Link to comment Share on other sites More sharing options...
pantzdown Posted October 31, 2011 Author Share Posted October 31, 2011 hello again, i have taken the motherboard out of the case in preparation to do the paper clip test tomorrow, and the test you are referring to is the power switch header on the MB ? also i just sent Gigabyte the serial number to the MB i think its still in warranty,( possible good sign ) will know for sure once i get the email back. Thanks, Link to comment Share on other sites More sharing options...
Synthohol Posted October 31, 2011 Share Posted October 31, 2011 no, you could have left it in the case. see post #4 i suggested unplugging the 24 pin connector and use the paperclip as per the link. Link to comment Share on other sites More sharing options...
pantzdown Posted October 31, 2011 Author Share Posted October 31, 2011 oh well its out now, i am going to do the paper clip test in the AM, also test the board while its out of the case, i also needed the board out for the S/N of the board, plus the CPU fan was caked in dust, it needed to be cleaned. i will probably know where i stand in the AM. Thanks. Link to comment Share on other sites More sharing options...
pantzdown Posted November 1, 2011 Author Share Posted November 1, 2011 Good morning, well i did the paper clip test. with the fans connected and the only fan that came on was the PSU fan, i did the test several times, with just the PSU fan came on each time(spinning). earlier in the post when i had everything connected the system fans and the PSU fans did come on, did the paper clip test suggest that i have a short in the PSU ? Thanks. Link to comment Share on other sites More sharing options...
Synthohol Posted November 1, 2011 Share Posted November 1, 2011 if there is no power to the molex connectors yet the PSU fan spins i would use the "Request an RMA" link and replace it. sorry for the news. Link to comment Share on other sites More sharing options...
pantzdown Posted November 1, 2011 Author Share Posted November 1, 2011 Hey that's why i went with a corsair PSU, well thanks for the help, on the RMA link on the drop down box where it says 'select your product from the list' what option should i use ? 750W UK ? even though i brought the PSU while i was in the US ?. Thanks. Link to comment Share on other sites More sharing options...
Synthohol Posted November 1, 2011 Share Posted November 1, 2011 thats fine, in the comments section you can either re explain the pond crossing or provide a link to this thread and specify what model you are sending back and what model you need for your locale. again sorry to hear of your issue.

pantzdown Posted January 15, 2012 Author Share Posted January 15, 2012 Hello Everyone, i am back again. i have had my motherboard tested, got a new CPU, and i am still not getting a POST, (see Attachments and previous post) i was to send my PSU but the price to ship it was very expensive, i did all the test in the previous post and it was determined that i get a RMA for a replacement PSU. can i still get a RMA for the PSU? is there any thing i can go to get corsair to accept the shipping charges to them ? Thanks ps can i get an advanced RMA. Link to comment Share on other sites More sharing options...
peanutz94 Posted January 15, 2012 Share Posted January 15, 2012 You would have to call customer service and discuss that information with them. You can use the toll free line and if you are outside the US you can install SKYPE and use that to make the call. Link to comment Share on other sites More sharing options...

parsec Posted January 16, 2012 Share Posted January 16, 2012 FWIW, the manual for the mother board shows a -5V pin on the ATX 24 pin mother board power connector. A TX750 does not have a -5V rail. The picture and text for the connector might just be a copy and paste error from older manuals. This board was first available in early 2009 from what I can see, which is not that old. Could it really need -5V power, and fail to boot due to the lack of it? Link to comment Share on other sites More sharing options...
pantzdown Posted January 16, 2012 Author Share Posted January 16, 2012 Hello, Thanks for the reply, if the TX 750 does not have a -5v then why was this machine was working fine the last time i used it, (April 2010,)and was working since the build in April 2009, i have since move to the UK, had it shipped over, when i opened it up before i powered it up, i noticed someone had been inside it, loose MB, CPU was taken out and put in backwards, i have had the sent out and tested, i have replaced the CPU, so i am confused why its not posting,:confused: Link to comment Share on other sites More sharing options...
Synthohol Posted January 16, 2012 Share Posted January 16, 2012 the 5v ground was removed from the ATX spec a long time ago, its natural to see it missing. Link to comment Share on other sites More sharing options...

OMG, was your PC "searched" in customs? Who knows what else happened when it was opened up, that is a real shame. Would locking the CPU socket with the CPU in backwards damage the socket? So the board was tested? Assuming your PC was searched in customs, and they seemed to remove the CPU, IMO opening the PS would be rather obvious too. Are the warranty seals on the PS intact? What a disaster, good luck with that. Link to comment Share on other sites More sharing options...
