random freezing in Windows 7,cause of this?
Dear members,
I bought all new components 3 weeks ago,and my sistem is as follows:
MB: Asrock 990FX Extreme3
CPU AMD FX 8120 FX with stock cooler
RAM Kingston KHX1600C9D3 2X4GB @ 1600MHz.
PSU: Fortron Raider 650 W
HDD: WD Green 1TB drive (sistem)+separate 500 GB WD green
chasis: Aerocool VX-e
optical drive:Pioneer DVD-RW.
Only my graphic card is old one but worked normally in other pc.It's ATI HD 4650 512MB DDR 3
I tested my pc with all kinds of software (OCT,Intel burn test,aida64 stab. test) for voltage stability and temperatures.My cpu goes max 61 C in full load , in idle round 45 C.And voltages that I get under full load are stable.
I played some games,and first froze was in a pc game after like 15 min of playing,second and third while browsing over internet and forth while watching a mp4 video.It just hangs with weird sound and it freeze.I had to reboot it.It just happens maybe after 2-3 hours of work,but 3 x it happened in Windows.
I went through pc mark7 and 3d mark06 test went normal,no freezing.
This stock cooler is very loud and in some moments it gives me even 5500 rpm.After the reboot I went to BIOS to read temperatures,I got cpu temp round 46 C,mainboard 41 C I think.
I've tested RAM with memtest86 no errors,went through OCT with 1h test no errors.I've put xmp profile for RAM in BIOS.
I've installed all the drivers from a CD I got with my MB,and put cataylst newest drivers (before this beta release).
All the time I was downloading something so my network card was working (I've installed broadcom drivers too).
Any help what causing this would be much appreciated.The problem is I bought components in other country so it's hard for me now to ask for warranty...and I still don't know what is causing problems..
If anyone could know what could it be,I'd do as you say.
