I have recently completed a build for an HTPC where the system will freeze and then restart repeatedly, and I am trying to determine if the board should be sent back for replacement.
Board: Intel BoxDH67BLB3
CPU: Intel Core i5-2500K Sandy Bridge 3.3GHz
PSU: OCZ ModXStream Pro 500W Modular
Memory: G.SKILL Ripjaws Series 2X4GB DDR3 1333 Model F3-10666CL9D-8GBRL, installed to slot 1 & 3
HD: Hitatchi Deskstar 5K3000 HDS5C3020ALA632 2TB installed to SATAIII port internally
Optical: Samsung BluRay combo SH-B123L also sata III internal
Video: initially on board, but had multiple freezes with shimmery video with any version of intel display driver tried,
replaced with ASUS GT 430 DiretCU Silent PCI-e, driver from NVDIA site yesterday, no shimmery video now (HDMI for all video internal / discrete GPU)
OS: Win7 Home Premium SP1 installed clean via USB stick, windows update current as of today
BIOS: BLH6710H.86A.0125.2011.0705.1517 updated within the last week as part of troubleshooting
Software installed: using media center to record TV from silicondust HDhomerun external tuner (recorded a show successfully earlier today)
Google Chrome (latest)
Updated to .NET4 from microsoft site (required for external tuner software). Freezes occurred prior to any of this software being installed.
Currently no antivirus installed
Updated via Intel site for this board (yesterday) latest chipset drivers
Ran Intel Processor diagnostic today: passed
Consistently will hang when trying to 'rate' Windows system once it gets near the end in testing the processor. Other screen freezing (and then system auto restarts after approx 5 min) will occur when trying to install software (happened today installing Java).
Any suggestions / guidance are very much appreciated!
Please try loading the Intel(R) Desktop Utilities, to determine if there's any overheating on the system:
Also, try running the system with only one system memory module installed.
Finally, to discard any software issues, try running a clean OS installation; or use a different hard drive to create a new OS installation and test if the problem keeps happening.
