Help me troubleshoot a very odd issue?

post #1 of 7
Thread Starter 
First off, thanks for reading and possibly helping.

About a month ago I had an Ultra X4 850W PSU blow out on me. Turns out one of the little flat capacitors blew off in a flash of smoke. So I RMA the bad PSU and ended up getting their upgraded version.

My problem now is, my damn system won't turn on. Won't boot at all!

I did a leak test on the system and plugged in all the Molex connectors. My lights, a few fans, the water pump, etc all worked. Leak test behind me I plugged in everything else. I double checked everything was still tight in their sockets - RAM, GPU, etc - and all cables were fitted correctly. Now this is where it gets strange. I have an Asus maximus mobo, the one with the water cooling built in. The board looks like it is getting power because all the LEDs turn on like they should. USB ports are also getting power.

My problem is when I press the power button on my case, it does nothing!

I verified that the cable to the mobo to turn it on is fitted well and has not come lose. I did various testing with only some items connected to power. Nothing. I changed the power cord for the PSU even!

Has anyone had this issue before? Anyone have any clue on how I can resolve this?

I had a Asus Blitz Extreme motherboard and quite some time ago now the psu blew up like yours. The lights on the board lite up and everything seemed fine but no go just like you, turned out the psu blow out killed my mobo ( 2 weeks old at time ). The psu had damaged several tracks within the pcb and fried 2 of the chips on the board, so the board would lite up but no chance it was gonna work again.

So it is possible that your psu has damaged some other component in your system that is not easily visible. Without having a bucket full of spare parts to hand you will have trouble diagnosing which part/s are damaged but i would suspect your mobo maybe fried. You seem to have a good trouble shooting mind and have tried to figure it out but if it is something other than the psu it will be hard to diagnose. Try removing the motherboard and look for burn damage. Sry for no better news frown.gif

Is there a Power Button on your mobo to circumvent the power switch on your case, shooting in the dark here?

Have you tried to unplug your PC and tried pressing the power bottom lots of times
Sometimes my PC wont turn on for some reason and that trick will work

As far as the extra button on the mobo goes, no, I don't think it does.

Thanks for the detail Mr-Mechraven. I wish I just had a way of testing to see if it's actually my mobo or not. I have looked at pretty much every chip and I don't see anything wrong at all.

I wonder where I should turn if my mobo died out in that way? Would I send it back to Asus under RMA or should I talk to Ultra about it?

Well if you could get hold of a friends motherboard or maybe buy one as cheap as they come to test with a cpu ? If you can borrow one then great, if not look on ebay or similar for a cheap cheap cpu & mobo combo that will at least get to post screen, that way you will know if it is or is not your mobo.

Btw my mobo looked fine as well, i could not tell just to look at it if there was damage or not. If your using a modern board which is likely to be multilayer pcb design in which case some damage will not be visible as the fine copper layers are inside the glass fibre layers and then under silk screen print making it impossible to tell. Even just looking at the chips on the surface wont show damage in most cases.

If the board is still under warranty then try by all means to rma for replacement either with Asus or original supplier, however i would not mention a blown psu as it likely they will not accept it.

Failing the above, strip the system down completely to all component parts , inspect, then rebuild step by step completely and see if it works.

Yeah, I am going to also go get a PSU tester just to make sure that it's not the PSU. It's possible not enough power is coming off the rail to power the system, but still enough to power the LEDs and fans. After that I am going to just do a rebuild. Failing that, I don't see what else it could possibly be other than my mobo.
