Has my new HX1200 PSU fried my machine?

Hi all,

I wanted to add a GTX Titan XP to my 2x1080Ti PC and I knew I needed a new PSU so I bought a Corsair HX1200 (my RM1000x wasn't powerful enough for the 3 GPUs).

First problem was that the new PSU wouldn't boot my PC, so I though oh well I've got a bad PSU.
I swapped the original one back in and now I'm getting constant BSOD with WHEA UNCORRECTABLE ERRORS. The setup is exactly the same as it was before.

Yeah. great huh?

While trawling google, one of the fixes is to remove the overclock on the CPU. Can anyone help me remove the overclock on my CPU to see if that helps? It was preinstalled when I bought it from PCS.

The machine I bought from PCS has been amazing and hadn't crashed in the 2 years I've owned it. So I'm a little surprised if the overclock is causing the problem but I have to try it.

I would ideally love to be able to have the 3 GPUs but I really just need it at least back to how it was for my work.

If anyone has any suggestions I'll be your friend for life.

Many thanks,
Donny.

As you’ve got a new PSU, the voltages will be a little different. I would try resetting the BIOS to defaults so it’s a clean BIOS by resetting the CMOS, then manually reapply the overclock profile and see if it’s more stable.

Hi,

Sorry for the late reply, I ran a memtest overnight and that returned 0 errors.

I reset the BIOS to optimised defaults but that hasn't helped, still getting WHEA BSOD errors.
For me to reset the CMOS, Im not sure how to do that. Do I just take the BIOS battery out for a minute or two? Would that do it?

Thanks for your help.

Yes that would do it, but make sure you've disconnected the power cord and earthed yourself

Hey,,

I reset the CMOS and set the BIOS to it's optimised defaults, but the machine is still crashing.
I don't really care about the overclocking, I just need my machine to work.

Im a little confused now. How can installing a new PSU (then removing it and putting the old one back in) render my machine almost completely useless?

I think it's quite a coincidence that a rogue driver update would have happened at the same time.

Anyone have any other ideas?

Thanks,
Donny.

Are there any dump files in C:\Windows\Minidumps or is there a dump file called C:\Windows\Memory.dmp? If so, upload these files to the cloud somewhere and post a link to them here. I'll gladly take a look to see whether they offer any pointers.

All the mindumps (all 8 of them) tell the same story, they're all WHEA_UNCORRECTABLE_ERROR failures with a reason code of Machine Check Exception. The failing driver is GenuineIntel.sys which means they're all CPU related.

I see that you have an overclocked system so the first thing to do is to disable the overclock and run everything at stock frequencies.

I've not looked at the kernel dump yet (it's still downloading) but I'm pretty sure I know what I'll find.....

Hey! Thanks for your help, sounds like we might be getting to the root of the problem.

I bought the PC from PCS with the overclock already on the CPU. I've reset the CMOS and restored the BIOS to it's 'optimised defaults'. Does that mean the overclock is off now? There's nowhere in the BIOS settings that says anything about disabling the overclock.

Thank you.

I'm afraid that's beyond my expertise. I'm sure others will be able to advise how to ensure the overclock is disabled.

For the record, the kernel dump told exactly the same story - interestingly the process involved was the idle process which basically just loops waiting for work.

Ok, that's a bit of a weird one. I'll maybe give PCS a call and see if they can help me disable the OC.

Having played with it, I am actually starting to be able to make it crash. I'm a designer and use a lot of 3D design tools, so every time I try run Maxon's C4D it crashes the system. And I've not installed any updates to that for months.

The weirdest thing is that I've been using the PC for over 2 years and it's been rock solid. Only since I tried to install my new PSU has it completely lost it's sh1t.

Thanks for looking at it.

Onwards...

Check that your RAM cards are fully home. Pop them out and reinsert them fully. It's possible that you disturbed them (or even something else) when you replaced the PSU.

That was my next step, then I was going to redo the cabling too in case that also got nudged.

I'll let you know how I get on.

Just re-seated the RAM, all nice and snug. All other cables nice and tight too.

Running out of ideas now. Anyone else got any suggestions they'd like to chip in with?

Can you still make it crash then? Any dumps?

Check the Nvidia website to see whether there is a later driver for your graphics card. Graphics drivers do change quite often and the Windows update libraries sometimes don't have the very latest version.

If it's a graphics intensive application that causes it to crash it's also worth popping the graphics card out and in - and any other cards too.

Yes, it's still crashing. Same WHEA errors. Here is the dump it created: https://we.tl/t-7WMiVZFfLv

I've taken the cards in/out, put one in; crash. Then two; crash. I've tried different slots on the mobo too.

Yep, it's the same BSOD and with the same GenuineIntel.sys driver. For some reason your CPU is not happy. Are you sure the new PSU was a direct replacement? Is there any way it could be connected wrongly? (Hardware isn't my forte).

If the only change you've made is a new PSU and now the CPU is unhappy then perhaps the CPU voltages are wrong somehow? The hardware wizards on here will know more about that that I do.

Yes, I think it has to be connected to the new PSU I tried to install. It was an upgrade in the sense that it's a corsair psu and all the cables and ports are exactly the same on both. Since I tried and failed to install it I've reset the CMOS and BIOS and it's still crashing. I've kind of stopped thinking about the new PSU. Im just trying to get it back to how it was.

Maybe I'll try updating the Nvidia drivers. See what that does.

UBUYSA, thanks for your help.
