Hello all, I hate to have to bother you all with my problems but I am just at wits end. (I also apologize if this in the wrong section) I just built a new rig for a friend last night and all was going smoothly. Assembly went well and Windows installed and booted with no problems whatsoever. I was about to let my friend know he could pick it up soon when the darn thing froze up, blaring audio full volume out of the speakers. After restarting, I reconfigured the sound drivers which seemed to fix that issue,so I moved on to running windows updates. While running the updates the system froze up again, not responding to any inputs whatsoever. When restarting the system it froze up yet again, this time during the splash screen. I updated all of the drivers and flashed the bios to the latest version and the system still freezes randomly, during boot and operation. I ran Memtest86 to see if the memory was faulty and around 86% through the first pass the machine just completely shut off, didn't freeze, just powered off.

I've been keeping an eye on the CPU temperature with the included Asus software and everything seems normal, never getting above 45C even under moderate load.

Google tells me it could be a faulty power supply or motherboard, but I really have no idea at this point. I will say the PSU makes a grinding noise, but I checked that and It's just the fan bearing.

I'm not as experienced as some people here, but this isn't my first build either. This particular one is my fifth.

Specs of the system are as follows- keep in mind that it's not a gaming rig

Motherboard- Asus B85M-G
CPU- Intel Core i5 4570 (with stock cooler)
GPU- MSI AMD Radeon 6450
RAM 2x4GB Patriot viper extreme (1600mhz)
SSD- Crucial M500 120GB (Windows installed here)
HDD- Western Digital Black 1TB (storage)
Wireless card- Trendnet N600 dual band wireless adapter
DVD drive/burner- just some asus drive, works fine
Case- Cooler master Elite 241 with included 550w power supply
Monitor- AOC 23inch LED IPS flat panel

Since you are also locking up and not just completly shutting off I would suspect that it is not the PSU, but since it could be just supplying undervoltage we can not rule it completely out.


Start by removing a memory module and test the computer wiht it out, then test that module in another slot, do this for all memory and all memory slots on the board until all ram and all slots have been tested.

If all memory sticks in all slots had problems then move on to testing other hardware. Try using integrated graphics on the board if it has it, try unpluging all unnecessary items (wifi card, dvd drive, etc), as well as any unneded periphial devices pluged into the computer, external drives, sd card readres, etc, etc

You obviously have a system of your own.
So my advice would be to test the new built with, a Psu out of your system that works well.
As a rule any power supply that comes with a case, are not tier one built power supply's.

If you say the bearing of the fan in the Psu sounds like its grinding or making a buzzing sound. it may be the cause of why the psu is shutting down.
It may be thinking through a protection circuit it is broken.

I don`t trust PSU`s that come with a case, because they are cheap Chinese ones just to get you started.

See if your psu makes the system stable.

It might be the PSU since the ones that come with cases aren't usually reliable but it may be another issue. I would check that all PSU cables to motherboard are firm in place. Also you might try it without the gpu and intel HD might be the same or faster in any case. Try removing the GPU and see if anything happens. Also since this is your 5th build, maybe try using another PSU and see if it works. GL.

Thanks everyone. When I get off work later I'll first try swapping the memory out, then if that doesn't help, I'll swap out the PSU. I'll try the GPU last because if the problem is with the power supply, removing some of the load might cover that up. If all else fails I can assume it's the motherboard then?

Sorry this response took a while, I've been sick the last few days. Turns out the main issue was the RAM; I swapped out the Patriot sticks for the Corsair ones in my brothers rig and it worked all day with no issues. I returned the defective ones and got some Kingston HyperX instead, works flawlessly. While I was at it I returned the case/psu combo as well as the GPU. I didn't notice it earlier as I initially used DVI, but the card's HDMI port was broken. I can't believe that I had that many defective parts, but I guess it happens. All is well now, brand new case, Corsair power supply, and ram. Machine is very fast even without the graphics card, Intel really has come a long way from the early extreme graphics days. It will hopefully last for years now as a light duty photo editing and organization rig, and general purpose PC. Thanks again!
