Hi,
I brought a second hand PC that was not powering up, suspecting it was only a faulty PSU. The PSU was indeed faulty and I have replaced it, but the system still will not start up; the fans on the water cooling unit spin for half a second and then stop.
When I replaced the PSU I noticed the plastic around the two 12V pins on the 24pin connector were blackened and I had to force out the old PSU's connector and clear the fused plastic out of the mobo's connector. The two pins still look quite blackened though.
I have tried clearing the CMOS.
If I disconect the mobo and use the "paper-clip trick" on the PSU, all the fans start fine.
I figure the 2 main suspects are the male 24pin connector on the mobo or the mobo itself. Which means I'll either have to clean up/replace the connector or replace the mobo.
So my questions:
1) How would I clean up the connector pins?
2) Where could I source a replacement connector, could only find a couple of US sites selling them (not too keen on soldering, but sooner that than new mobo)?
3) Worst case, buy a new mobo; any recommendations on what I can replace a Asus p7p55ws supercomputer with that will support 3 graphic cards?
Some specs:
- Water cooling system (all gpus and cpu) - appears to be functional
- Two extra case fans - working
- 3 gpu cards, all ATI Radeon 59XX (look like 5970s), I only intend to move forward with 2 fornow though - status unknown
- Mobo is a Asus p7p55ws supercomputer - possibly faulty
- Not sure on the CPU, previous owner claims AMD, but mobo is a socket 1156
- Ram 2x4GB SK Hynix PC3-12800U DDR3-1600 - pulled from working PC, so should be ok
- PSU, corsair RM850x
The machine was kept in storage for 3 years prior to me buying it.
Any help/advice would be appreciated.
Thanks
