Hi guys, I just built a micro itx computer. The components are as follows: Mobo: AsRock Z77E ITX CPU: i5 2550k / Xeon 1230v2 (both tested) GPU: XFX 7850 2GB Ram: CORSAIR XMS3 8GB (2 x 4GB) DDR3 1333 (PC3 10600) Power Supply: Silverstone SST-ST-50F-P 500 Watt 80 Plus Bronze Cooler: Asetek (generic H50) 120mm cooler Temperatures for both cpu's idle: 28*C Load 60*C. Issue: Crashes and restarts to Windows (not even a BSOD) whenever I run Intel Burn Test, Prime 95, or even the last 3Dmark11 Combined test. No Error, no BSOD, no Error Codes etc. The 2550k was less tolerant than the Xeon 1230, and crashed instantaneously, the 1230 runs a bit longer (like 2 minutes). Everything stock. CMOS cleared. No overclock. Fresh windows 7 home premium install with SP1 and all updates. The Ram was tested on a different computer with memtest for 12 hours no problem and p95 for 24 hours. I tested both processors and the issue occurs with both. I thought it might be a short in the power switch I had made custom out of a momentary switch, but a different switch didn't fix it! I am going to borrow a power supply and test it again with a different supply to isolate if its the motherboard or the power supply. Do you guys have any suggestions? This is really frustrating.
