This computer works well except for two problems. CRC doesn't seem to work on this computer - when extractive archives or installing it often fails because it doesn't pass the CRC test. However if you force WinRAR or uniextract to keep broken files they work perfectly. The other problem is that the computer occassionally gets blue screens. IRQL Not less or equal with the 0x0A stop code. Doesn't point to any drivers, and I've reinstalled video drivers and have all other drivers installed. There's only one unkown device on the computer, don't know what it is but I know of a problem that can tell me... will have to do that later. I've attached some minidumps, if anyone is willing to check over them in their spare time and help me narrow this down it'd be great. I'm following all the steps in the sticky now. [edit:] Also ran memtest from UBCD and it passed alright. Didn't run any extensive 72 hour test or anything but it passed all the standard tests. Thanks.
