CUBS!
Hi Guys,

I'm in desperate help and would really appreciate it if you guys could help me out here.

My computer randomly starts looping sound and my monitor turns off for some reason, mainly when playing games or music. I have no idea what's causing this crash. Compute specs below, if need more info, let me know.

Computer Specs:

Operating Software: Windows 7 Professional
CPU: Intel(R) Core(TM) i3 CPU 550 @ 3.20GHz
Motherboard: Gigabyte H55M-UD2H
RAM: Kingston HyperX Genesis Grey 16GB (4x4GB) DDR3 PC3-12800C9 1600MHz
Graphics Card: Sapphire HD 7870 GHz Edition 2048MB GDDR5
PSU: OCZ ZT 550W '80 Plus Bronze' Modular Power Supply
Sound card: Asus Xonar D2X 7.1 PCI-E Sound Card

Example Video of crash:

I only recently installed the sound card as I was hoping it may have been the onboard sound but it appears it's not.

Would be grateful if someone could assist me in resolving this problem, it's been occurring for months and I've just got fed up of it.

Cheers.
 
The first thing I would do would be MemTest the RAM, if you haven't already.

Edit: Could you get hold of another graphics card to test it?

The graphics was recently replace too but that didn't really help either.

I've never used memtest so will look at doing it now.

Yeah, MemTest is a handy tool. You'll at least be able to rule the RAM out as the cause, with an added bonus of knowing how to use MemTest.

Are you overclocking at all? Are you using an SSD? Possible compatibility problem? Has it been like that since you got/built the PC?

Failing that I would start to think about testing the PSU, not always easy I know. All you can really do is to replace each individual component with known working components.
 
how much dram and qpi/vtt voltage are you using? youll need a big bump in qpi/vtt with 16gb

99% sure its memory related qpi/vtt too low
 
It was all pre-configured as I bought it from Overclockers.

The CPU I think was overclocked, I can't remember lol.

I had to replace a OCZ Stealthxtream 2 500W PSU just before I replaced my GTS 450, the PSU was sparking and giving off a burning smell, perhaps it short circuited the motherboard?

I also use Truecrypt to encrypt my whole drive but I highly doubt this is the issue.

My internal HDD is a WD Caviar Blue 500GB SATA and I use 2 external hard drives. One WD My Passport 500GB USB 3.0 hard drive and a caddy to use 3.5 internal HDD.

Which memtest software should I be using, I see quite a few?
 
try memtest86 run three of four x of it to fill up 16gb

look in the bios for dram voltage and qpi/vtt voltages it will be in the m.i.t section and post back the amounts or look in easytune/voltage1 the power on and target amounts

I have no idea, I'm a noob at this, would you mind going over this with me?

Lots of things in this have been replaced, 8GB Kingston HyperX Blu were replaced with 16GB mentioned above. I have no idea if he reset the RAM in BIOS.
 
no you need to look in tuner/voltage1 i forget now but think its that

it will list all the cpu qpi/vtt voltages and say power on-target

set that to 1.315v and dont be scared to use that amount i have an h55 board that uses that much for 8gb of memory

who overclocked that machine? you could improve things to use power saving but thats another time first get it stable

you can also try enabling x.m.p for your memory if it supports it

^^ this is up to you but cpu clock drive is nearly always 800mv not 900,it might help


if you did want to use power saving where the cpu overclocks and downclocks itself in speed/voltages you need to set cpu voltage in the top screenshot to normal(youll see normal in voltage list) that unlocks dvid for adjustment then enter +0.1625v which gets added to your cpu's stock voltage of 1.1875v=1.35v at cpu load

but just set the qpi/vtt to 1.315v first then see if it locks up in games

Sorry, just to confirm, if I change CPU clock drive to 800, will I need to change anything?

I can enable XMP to "profile1", do I leave the settings to the default?

OCUK overclocked it, I bought one of the systems back in Aug 2011

Edit: qpi/vtt was set to 1.310v not 1.315 as that was not available.

first leave those and just change qpi/vtt voltage from auto to 1.315v and then test with some gaming and post back
 
I'd remove the overclock when fault finding.

Use Prime to test the CPU (+ram to some extent), memtest to check the ram, and the Heaven benchmark to test the graphics card.
