a) on both Memtest86 v3.3 and Memtest86+ v1.7 the RAM passed all tests continuously. B) I'm sure the SATA cables are fine as I used to use them, but I'll swap them over with some new ones now c) PSU should be fine, I've stress tested it recently with no problems Installation wise: a) Setup did detect the RAID and was able create a partion and do a full format. (Also there is no other HDD connected at this point) B) Install fails after it's final restart. i.e.: 1. Blue screen install where you select partition, format and copy over install files 2. GUI install with tasks on the lefthand side and where it would ask for network settings, CD key, timezone, etc (thats all automated though because i've entered all that info in the answer file using nLite) 3. After GUI section, the computer restarts, shows the Windows Logo on the black screen with the progress bar, then a low resolution, light blue background with a cursor, then blue screens c) I always get the following BSoD (last three variables may change, but the first is usually 0x7): BAD_POOL_CALLER 0x000000C2 (0x00000007, 0x00000CD4, 0x00000000, 0xE1600004) Hope this helps. I really appreciate your help.
