I've been having this problem from some time now. My computer randomly locks up, it's not shutting down or going to blue screen. It just locks up and stays there until I hard reset the entire computer.
My computer specs.
Intel Quad-Core i7-920 L3 Cache 8MB 2.67Hz 2.79Ghz 2793 Mhz.
Nvidia GeForce BFG OC MaXcore GTX 260 896 MB DDR3
6GIG OCZ Triple Channel DDR3
Gigabyte Technology Co, Ltd Untra Durable 3 DDR3 Freq 1366+
2x Terabyte Western Digital HDD
OCZ GameXStream Power Supply 750W
Micrsoft Windows Vista Ultimate x64
When I run SpeedFan 4.40 my CPU core temp for all 7 cores are sitting at about 42-45c without any applications running. While I'm gaming they normally hit about 50-55c. At first I though these crashes may have been caused by the CPU overheating to I was thinking about picking up an Hydro Series H50 CPU Cooler but I really doubt this would resolve the issue. My GPU cloaks at about 50-52c without applications running.. even that's rather high. But again, I don't think overheating is the issue.
I've updated all the hardware in my computer to the latest that was available and BIOS. This problem started happening a few months ago, and today alone I've had 3 lock ups in the last hour.
Any help would be great!
Thanks in advance,
