Motherboard problem

post #1 of 2
Thread Starter 
Hi, I have built a PC out of Corsair ax 850, 6gb of xms3 1600 ram, vapor x 5870, Swiftech 360 rad watercooled i7 930 on a Asus p6x58d premium on a slightly modded haf x case with shroud mods and push/pull fan setup. It was good for around 2 months of playing games like Crysis and Just cause 2 and Black Ops at max setting with temp of around 30c at load and 24c idle.

It was a great PC when it worked. Then it just went and messed out on me while i was transferring music files to my ipod. After I transferred some music to my ipod and removed it safely, the USB root hub started to act weird and kept saying there's a unidentified USB device and saying it has malfunctioned whenever i tried to reconnect my ipod, and it wont recognize my ipod at all on all the usb slots except for the two slots thats for my kb and mouse.

Somehow, those werent affected. So I'm thinking it's an ipod problem. I tested the USB ports out by sticking my WD Elements, no read. It will spin it, but wont recognize it. Then kingston data traveler, wont read that too. This was the same for all the usb ports except for the only two that was for my kb and mouse.

Somehow, when I plugged in the external hdds to the USB ports that the kb and mouse were plugged into, they worked. So I unplugged the kb and mouse and tried putting that to all the ports that was not reading the externals. The led light on the kb turned on when i plugged it into the ports but it wont type or work even though its a plug and play and before this happened, I used to unplug and replug it to different ports whenever i was at lan parties with this same PC with no problem before this happened.

So I tried a solution of using a ps/2 kb and mouse and uninstalling the USB root hubs and the host controllers and rebooting the PC. Reboot installed all the host and roots back, but same problem except now, NONE of the ports work!

So I uninstalled the roots and hubs again and reinstalled the ichor 2.0 and marvell 3.0 USB drivers and reboot...still not a single damn port works now. It still spins the external drives but wont recognize and now its not even lighting up the kb...wow.

So now I tried clear cmos reset switch at back of the mobo i/o panel for 15 seconds, then even just went to bios and set to defaults and cleared my oc'd ram settings. After doing that...whenever I try booting, it goes to Windows 7 logo, then bsod crashes and reboot itself. I fixed that part using win7 repair disk, and fiddled a bit more by rolling back drivers again.

That must have ticked it off even more somehow, as now I can't even turn the PC off by means of the case power switch. Now, the PC is bread-boarded. The p6x58d has a power and reset led switches thats on but it wont even post. I Cant even turn this on now..omg

Anyone with insight to this tell me what i did wrong and what was the problem and how do I fix it correctly later on?

What brand of motherboard should I get next time and if it's not my fault but this asus mobo fault (this one was a replacement btw, had another same one that stopped posting after two days of lan gaming), wow do I rma this from Asus?

First one got replaced through Amazon, but i've had this one for two months so i am over the return window.

Thank all of you who read this because it was a long post and I apologize for taking anyones time. This build with all the fan mods and minor case mod and custom watercooling put it at around $3000. I keep wondering why it keeps dying and the source of it keeps going to the same mobo. It's wonderful when it works though.

The board is most likely damaged in some way or form. If it starts out small and gets worse like what you posted, your board is failing, most likely the southbridge is going out.

What i would do first is check for physical signs of failure eg blown caps, scorch marks, things of that nature. If everything checks out, then its most likely the southbridge as pretty much all USB ports connect to their controllers on the soutbridge.

Replace the board, i dont think its worth saving anymore.
