A week ago a assembled an ECS bare-bones and computer kit. The included the following:

OS: Windows 7 Home Premium 64bit
MOBO: ECS A55F2-M3
CPU: AMD A8-5600k w/ integrated Radeon Graphics
RAM: 8gb (4gb x2) Kingston DDR3
PS: HEC HP485DR ORION 485W
HDD: 1TB eSata Seagate

Since the system's initial assembly, it has randomly shut down at various and unexpected times. This happens sometimes when the system is idle and other times while I am working on the computer. When these shutdowns occur, the computer is completely unresponsive, however all of the lights and fans continue to spin. The power and reset buttons do not work, and in order to restart the computer the power supply must be unplugged/turned off and subsequently turned back on. I have already done the following in order to weed out some problems:

1. Checked the RAM - both sticks are healthy and seated well in the MOBO
2. Checked the power supply - it runs at a consistent voltage, providing 1.3 - 1.5 volts to peripherals (hdd,
cpu, rom, etc.)

I loaded the BIOS and found that the CPU idles at around 50C with a CPU fan speed of roughly 2,800 RPMs. Using Speecy, I discovered that while in Windows the CPU averages anywhere from 50C to 65C with temperature spikes as high as 85C every few minutes. In order to resolve this I first ensured the the Heat Sink/Fan was in place, which it was. The problem persisted. I then cleaned the HS/F and the CPU and reapplied a new thermal paste (Arctic Silver 5), the problem still persisted.

What could be causing it to overheat? I've done everything I can think to do, I've even initiated a windows re-install, just in case the OS was at fault for some reason ( I ran scandisc check and found a few corrupt system32 files). I'm desperate. I NEED HELP!!!!!

Check in BIOS (Advanced tab) Cpu Smart Fan Control (Enabled) Smart Fan Mode (Normal) save and exit BIOS, also check to make sure the processor is not overclocked, you could reset BIOS to default values, save and exit. Do not know how you setup the BIOS from begining. 3.6GHz should be what it is running or 3.9GHz in turbo mode.

Knightdog, thanks for the reply! I was starting to get worried know had any advice! I have the bios set to "optimized settings" which have the cpu smart fan function enabled as and running in normal mode. Overclocking is also disabled. The bios indicates a rapid temp increase 30c to 55c in less than a minute or two upon startup. I noticed that the cpu is getting 1.40 - 1.45 volts. Is that normal voltage without overclock? It seems odd to me.

file corruption is likely a result of system crashes due to the heat. And the reason it shuts off but all the fans are spinning is so the system can cool itself off. 1.4 is standard voltage for your CPU.


Just ruling out the obvious:

If you crack open the case, can you actually see the CPU fan spinning fast?

Did you accidentally plug the case fan into the CPU fan pins?

Is the heatsink appropriate for the CPU (it's probably the stock one, but just making sure).

Thank you for the reply, Twelve25. Yes, the fan is spinning during operation. The fans for the cpu and case are plugged into the appropriate sockets. The heat sink is stock. I'm relieved to know that the voltage is okay.

Doesn't sound like any user error. I wonder if you have a metal burr on the bottom of the heatsink or something preventing full contact to the CPU. About the only thing left is figuring out why the heatsink can't cool your CPU. Even with a small overclock, you should be able to run without thermal shutdown.

A metal burr... Hmmm. You know, the last tine i had the CPU out i noticed a little rough area on the sides of the metal cap, not the top, but the "walls" of the cap. It wouldn't effect the contact of the heat sink, but maybe this is the problem. I'm not sure. Maybe you are speaking of a microscopic burr.

It would need to be a big enough one to leave a gap preventing much contact between the CPU and heatsink. Tiny ones would mean you have maybe 10% too high temps, not instant overheat. Something is going seriously wrong there, though.

You probably just need to decide if you want to RMA or pick up a nice heatsink on your own dime. Getting a new better heatsink should allow overclocking too, so it's not all a waste of money.

Well twelve, I bought the rig from tiger direct, and they are pretty good about returns. I called ECS about the problem and they want to "service" the mother board. I think I'll just send it back to tiger direct and get a new one, if i can. On a brighter note, i did reorganize my cables, and was able to get the temp stabilize at 50c in bios, but that is still way too high for a brand new system.

I hope they don't make you return EVERYTHING as a single unit that would be a nightmare. You will probably have to send back heatsink and CPU together, though. That might be nice as you can get a fresh start on both of those.

Do you have a rear exhaust or front intake fan on your case? I am surprised organizing cables made that much difference. Is your case really cramped?

The case was cluttered. It still over heats and shuts down, though. I don't have a front intake fan, just a rear exhaust. Just A quick update. I took the rear panel off the case to see if the temp would go down and noticed that the MOBO is bowed slightly at the precise location of the cpu. This would explain why A perfectly clamped heat sink and properly applied thermal paste would not be sufficient to keep temps down. The heat sink might not be able to make conduct properly. By God, I think e may have solved this problem!!! Tiger direct is sending a new MOBO... let's hope this works!

I will be interested how this turns out for you. I bought the same package, put it together over the weekend and am having the exact same issue. Kind of odd. Called both AMD and ECS. They both gave me a couple of things to try tonight.

Drago,i knew I was not alone! it's interesting that you Ecs was so quick to have the motherboard returned. It makes me wonder if that particular model has some type of dysfunction. I'm curious, what did AMD tell you might be able to fix the

Well, this was all before I found your posting. I tried TigerDirect first who said talk to ECS and AMD (before they will RMA anything). I called ECS first who said the stock cooler isn't good enough. I informed them I am not doing any OC so the stock should be fine. They suggested upgrading the BIOS. AMD said the problems sounds like a memory issue, if not then a CPU problem. I figured I would upgrade the BIOS, run Memtest overnight and go from there.

I've built quite a few combo kits for family/friends and have never experienced anything like this before. After I found your post, I was relieved to know I wasn't alone.

After trying things recommended by ECS and AMD, same problem. I found something interesting tonight though. I went into to the BIOS and disabled AMD Turbo Core under CPU settings (set to enabled by default) and my temps dropped from 64 to 47 while just sitting in the BIOS PC Health Status. If I disable the SmartFan function it drops even further.

I wonder if you will get the same results. Whatever is going on, it appears the stock cooler isn't enough.

I might just buy like a Coolermaster 212 or a TX3 and call it a day. Sure it's more money out of pocket, but so is shipping back for replacements 2-3 times until they figure out what it is.

The fact that you are excited to get 47 degrees in the BIOS (so no CPU activity at all) is pretty telling.

I had the same problem with it shutting down power button dead reset dead only way to fix it was cut the power to the computer it turned out to be windows 8 shuts down hard drive I disabled this setting to never and it has worked for 2 weeks now with no problem

I ended up ordering a CoolerMaster 212. Got it today and installed it. It made a huge difference. With Turbo Core enabled, temps dropped from 64 to 19-20. Looks like I am good to go now. Thanks.

Drago, It's good to hear that you got everything fixed. Unfortunately, even after replacing the MOBO and installing a CoolerMaster 212 Evo, the computer still shuts down. I even readjusted by power settings and told the HDD to never sleep, but that didn't work. I checked the BIOS and it now reads a cool 31C, however, when I check Speecy (the third party temp software) it reads 55C-65C. I trust the BIOS over Speecy, but I find it odd that there is a disparity. I'm at a lose. This one is a real stumper...

RedShirtArmy - Sorry I didn't post sooner. After about a week with the additional cooler, I started having the same problems again. Just random lockups. After swapping memory and the power supply as a test, I finally just gave up on the ECS board. I returned it and ordered a Gigabyte board. I have been running for about a week with no issues at all.

Could it be a bad CPU? I know AMD had a bad batch from the A10. Has the A8 had a bad batch?

The other problems I have read about similar to this is an outdated BIOS.

Hope this may help. I will look over some other sites and see if there is some other solutions.

Did anyone ever get this solved. It appears as if I am having the same issue.

Custom build:
ASRock FM2A75 PRO4-M MOBO
AMD A8 5600K

I'm not sure if it is due to overheating. I am using the stock fan. Windows 8 totally freaks out. My monitor looses it's signal and everything becomes unresponsive. Restart button won't work, I have to do a cold shutdown.

BIOS shows the CPU temp at over 52 C doing nothing with the CPU fan "Full On."

BTW while reading this I decided to install Speccy...

So far while reading this article
I have been running Prime95 for 45 minutes and installed Speccy and started up a few programs and all is rock solid, and completely responsive while at 100% utilization for over 45minutes now..
CPU is set on the minimum Bios over-clocking speed of 3900MHz
CPUz shows 1.344v

But per Speccy my CPU temp is 81 oC

I do not trust this as Speedfan gives me a steady 47-48 oC all the while I've been running Prime95
I also double checked by touching around the Heatsink/pipes and it was barely warm.
Clearly Speccy is not accurate (unless a reboot changed it).

I've been trying a few different systems out and am liking this APU processor (I'm not gaming with it).

My system:

ASRock FM2A85X Extreme6 MB
AMD A8-5600k
G.SKILL Ares 16GB F3-1866C10D-16GAB
Coolermaster 212 Evo with dual Arctic Cooling PWM 120mm fans (slow compared to most 120mm)
Coolermaster Elite 431 ATX case with two Arctic Cooling PWM 120mm fans (1 exhaust and 1 inlet)
500 Watt OCZ power supply with single 4pin 12v CPU power plug (for the 8 pin connector).

I also have the same problem and I also have that similar setup. My cpu temp fluctuates between 50-60 Degrees Celsius on HWMONITOR during idle and while running Prime95 it spikes up at 98-99 Degrees, which is really not common for a newly built PC. I tried lowering down my APU and the temperature during idle dropped from 50-60 to 50-55 which is still bad 🙁

AMD A8-5600k (Stock Speed), MSI FM2-A85XMA-P33, G.Skill Ripjaws X 2x4gb 1866, WD 500gb BLUE, CM Storm Scout 2.
