| 1407620 | 2015-08-30 22:19:00 | Hi.One dead computer which was fine until I hit the Power button to start it on my return home. I had shut down the computer and gone out for the day yesterday. I have done all the obvious checks/swaps of power cables to the computer and all is good there. I have also reset CMOS, replaced CMOS Battery, unplugged every cable from PSU except for the 24 Pin and 4 pin CPU cables to Mobo, HSF and Front panel PWR +& -. Also, I have swapped PSU with others from working PC's and still no life. The PSU from non-working computer works perfectly in PC's I used PSU from to test if it is a PSU problem in my PC. In my PC, there are no Beeps, no red power LED glowing on front of case, no amber lights on keyboard, no fans start spinning..101% zilch. I'm dreading that this is CPU or Mobo failure because from past experience the symptoms point towards that being the case. Though I am hoping someone could advise on something else I can do to test for the cause of the problem I cannot swap out the CPU and HS/HSF to test in another computer because I do not have another PC that uses AM2+/AM3 CPU. Also, I removed and reseated the RAM. End result, PC still dead. Com specs are: Gigabyte GA-MA74GM S2 AMD Athlon 11x4 630 CPU 4GB Adata DDR2 800MHZ RAM (2x2GB Matched pair) CoolerMaser RS 550 PCAR-ES PSU Onboard graphics or Gigabyte 8500 PCI-e 4xSata HDD totalling 3.5GB and 1x IDE ATA 320GB HDD (all unplugged from PSU and Mobo) LG Optic drive (unplugged from PSU and Mobo) Windows 7x64 Professional fully updated I spent a few hours googling my problem but all suggested remedies I had tried. Any help well appreciated thank you. |

| 1407623 | 2015-08-31 00:28:00 | Thanks Speedy. I had tried that and still no go. Sorry, I forgot to add it to the list of things I had done.The 4 pin ATX12v is connected to mobo too. | kioti (17360) | ||
| 1407624 | 2015-08-31 00:31:00 | What about the ATX2v connector if its got the header? Try connecting the main hdd see what happens Are you in NZ or somewhere else? |

| 1407625 | 2015-08-31 00:32:00 | psycik, thanks. I had done both of what Speedy suggested and still Dodo PC. Thanks | kioti (17360) | ||
| 1407626 | 2015-08-31 00:46:00 | Only other suggestion, have a look at all the USB ports, make sure the plastic tab in one has not broken out the the pins inside are not bent thus causing a short. If they are this will stop it from booting. | wainuitech (129) | ||
| 1407627 | 2015-08-31 00:47:00 | Hi Speedy, I'm in Dunedin NZ. the ATX2v header? What I have connected is the 4 pin connector from the PSU to the appropriate connector on the3 Mobo. It is to run the CPU. And I did try connecting the main HDD and no other hardware (HDD's and Optics) | kioti (17360) | ||
| 1407628 | 2015-08-31 00:52:00 | Some mobos have the CPU 4 pin header and an ATX 12v connector which can be 4 or 8 pin. This SHOULD be connected if the mobo has the connection If this is your mobo (www.gigabyte.com)the ATX 12v connector is the 4 pin plug behind (I think it's the video / VGA port) top right in the pic thats on the site |

| 1407629 | 2015-08-31 00:53:00 | Thanks wainuitech. I will give the USB ports a looking at. I know that that some on the back have become loose meaning that when I plug a USB device in that they feel loose fitting in the USB port....wear probably. But there is one of the 2 USB ports on the front of the tower that has lost its casing around it and attempting to use a USB device (flash drive/keyboard/mouse) just does not work and the other one of the 2 has that 'loose' fitting feel to the device that I connect. I will check it out. Thanks | kioti (17360) | ||
