Guys,
I just build a new box here are the specs

CPU: Intel Core i5-2500K Sandy Bridge 3.3GHz
SSD: Kingston SSDNow V+100 SVP100S2/96G 2.5
HD: Seagate Momentus XT ST95005620AS 500GB 7200 RPM 2.5" SATA 3.0Gb/s with NCQ Solid State Hybrid Drive
PSU: CORSAIR Professional Series HX750 (CMPSU-750HX) 750W ATX12V 2.3 / EPS12V 2.91
RAM: Kingston HyperX T1 Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 16006
MB: MSI P67A-G43 (B3) MB
HSF: Cooler Master Hyper 212 Plus (Artic silver 5)
GPU: SAPPHIRE Radeon HD 4850 X2 2GB
OS: Window 7 pro 64 bit

I have looked over the forums and have tried to over clock my CPU and every time I start to run Prime 95 "In-place large FFTs" test my pc will reboot in about 15 mins other Prime 95 test seem to work fine. It even does this at stock settings. That’s what has me worried that I may have something wrong.

The PC has never had any problems at stock setting. I play Star Craft 2, the Witcher 2 or any other game with no reboots no problems at all. Also other stress test like Intel Burn run fine no problem. My cpu temp never gets over 51 Celsius while using Prime or Intel Burn at stock settings and at 4.2 it never got over 61

Is this something I should just blow off to a wired glitch with my set up and prime 95 and I should just use Intel burn test to OC. Or is this something I need to look in to more? Anyone else ever have problem like this ?
