Hey guys,

Was just web browsing and the PC locked up. I opted to restart and went into a continuous power on - power off loop. Now I can't even get into any loop.

Specs are as follows:

MB: Rampage IV Extreme
CPU: Intel Core I7 3930k
RAM: 16GB G.Skill Ripjaws 2133
GPU: 2x Asus GTX670 DCII OC 2GB
HDDs: Samsung EVO 250GB (OS and Programs) + Crucial M4 128GB (Games) + Intel X25-M 80GB (Test VMs) + 3x WD 1TB (Mass Storage)
PSU: Seasonic X -750W

Here's what I have done so far:

Unplugged all drive except OS SSD.
Cleared CMOS - Taken out battery and placed it back and pressed the button at the back of the I/O
Pulled out one GPU and swapped them on each test.
I taken out the RAM and applied to each DIMM slot.

One plugged into power, I see the Start and Restart LED on the board light up.
The Bios light is on and have the ability to switch over pushing the button.
Green Lights are on the GPU signalling the OK for for it's connectivity.

If I press the Start button, nothing happens. I'm thinking that it's either the MB or PSU or even the H100.

Anyone have the same experience or insights on what this could be?

Greatly appreciated!!!

Yeah, it really sucks when it happens. I've experienced similar problems due to a bad PSU (a while ago). May be worthwhile to check it out. (Seasonic make great PSUs but ... you never know before you know, you know). Btw 750W seems a little low for your rig. Are you sure it's enough?

Other than that I'd check the cables (a/o possible shortcuts?) and finally take the MB out of the case and check if it would work out there. Good luck pal!

Hey WillyK, Appreciate your reply!

I have a feeling it's the PSU, It has been running rock solid in this particular setup for over a year and is solid during stress testing.

Perhaps it has run it's course, I may invest in a 950w or a 1000w.

I believe a little stronger PSU may be a good investment in any case (I'm currently using only AX1200/AX1200i on all my rigs). It'll give you peak capacity (rule of a thumb: never load more than 80% of your max PSU capacity 24/7), it'll be quieter, and it'll be more stable providing clearer power etc. It may even solve the problem if the cause is bad/insufficient power. Still, I'd have a look around for possible shortcuts or similar issues before disassembling the rig (last resort).

Could be your CPU I have the same issues you have. But my PSU is okay and so is my ram other options are the MB or the CPU. As my System sometimes runes normal , I guess it would hint a bad cpu. I would look at your cpu off the socket look at the pins reseat the cooler. Maybe that will help other then that PSU is a good point to start ^^.

I initially had the OS SSD mounted on the back of the MB tray and appeared to be shorting out.

I have since mounted into the drive cage and is working like a charm.

Looks like it's all back to normal for me.... Cheers!!

Well done and thank you for posting back the fix. Do you have any indication why the SSD has suddenly become conductive?
