CPU failures are rare at stock speeds, but not out of the question. I've occasionally (rarely, but I've seen it) had a CPU with dodgy cache, that could have issues.
The first thing I'd do though, is greatly relax your RAM timings. Set them back to the more common 9-9-9-24. You said your CPU is stock, but your sig says 4.4GHz; if it is overclocked, go back to stock.
Secondly, if you have a spare hard drive, I'd try doing a fresh install. No RAID, just in case the striping has anything to do with it, just a single drive. This also means that if it doesn't work out, you've used a spare drive and can go back to your RAID.
Remove the GT240 and 8400GS if they are in the system, and run the big graphics card by itself. These are the things I can suggest. If none of those things work, I'd try and borrow a CPU you can swap to test with.Edited by LoneWolf15 - 8/22/11 at 7:50pm
