Hello, recently i purchased components to build a new unit. The first week i did not use the new unit very much, but when i started to i noticed that it randomly freezes, with no windows log or error; the unit fans and cpu fan keeps working, the power light is on, but the hdd one turns off, i can"t move my mouse or anything, i have to reset the computer.
Those are the specs:
PSU nJoy 600WRX 600W
Zeppelin 8GB DDR3 1600MHz Dual Channel Kit
Hard disk WD 1TB SATA-III 7200 rpm 64MB Caviar Blue
CPU AMD FX-8320 3.5GHz
Motherboard Gigabyte GA-970A-DS3P
GPU GeForce GTX260
NO OC
I also have a DVD-Writer LiteOn IHAS122-14 and no external USB devices except mouse. At the back i have a 5.1 surround sound system and at the front jacks headphones and microphone.
My first tought was temperature, they were all fine, cpu hovers around 20 when idling (with stock cooler), after 4hr of gaming it averages 55, max ever was 61. I also read a lot of topics around here, so i tried to find the problem. I checked the HDD for errors, 2 times with windows feature, once with HDD Tune and once with WD's software, everything ok. But just to be sure i also tried another HDD Seagate 650gb 7200rpm, same problem. I tried on each HDD Windows Vista, and a few versions of 7, no luck. I tried to change the GPU, switched it with an older GT9800 for a few days, no luck, problem was still there. I've been contacting the warranty company, and they suggested some memory testing, did it twice with windows memdiag and with MemTest86+, i've been letting it to pass 9 times, took almost a day and no errors were found. They suggested a stability test with Prime95, it also passed (worked for a good amount of hours). After all this i went with the unit to warranty, for a professional check, and it came clean...witch was weird...cause they called me after 6 hours to give the results; and i told them that it can work ok for a couple of days or freeze more than 6 7 times a day, mostly browsing, idling or ocasional gaming, and they said that it doesn't matter cause the unit performed ok in their tests.
What i've noticed is that the freezes are more rare after i switched the power settings to high performance, but it still happens.
Before sending the unit to warranty i also checked for software issues, i've installed only mobo's drivers from cd after a clean win install, and let the HDD mostly empty, still happened.
My keyboard has a ps2 connector, hope i got it right, it is a no name one, worked fine on other 2 pcs that i changed in the past 6-7 years, and a USB mouse, Hama URage Gaming Mobile, it also worked fine on my previous PC for 7 months and on a laptop.
Now i don't know what else i can do, not even the diagnosis helped. Maybe they just tested what i've been testing, i really don't know. Hope they also checked the mobo, maybe there is a bad capacitor messing things up...
Problem seemed to happen more often when the cpu came from high frequency(3.7 amd auto boost when not all cores are working) to idling frequency 1.4, but it is not a rule, only somethimes did that. It happened 4 5 times while gaming and a lot while listening to music,browsing on forums or youtube and while the pc was just idling and not being used. I also tried to wait for a recovery when it freezes, but after 15-20 minutes i restarted the unit, i didn't want to risk it.
Can you guys help? I am really out of solutions now...and the warranty can only cover broken components, which apparently they don't find...
Thanks for reading.
