All but one of the dump files are STOP 0x124 - an error that's reported to Windows by your CPU. There isn't much information in the dump files - but it's certain that this is either a hardware problem (something is busted) or a compatibility issue.
Please read this topic for suggestions on how to troubleshoot it: http://www.sevenforums.com/crash-loc...-what-try.html
Additionally, one of the memory dump files is a USB driver issue - so I'd have to wonder if there's a problem with an attached USB device, the cables, or the USB ports themselves. I notice that you have a USB wireless device - and these are known to cause problems on many systems.
The issue about validation is that there's been changes to your core OS files - and that causes a problem with the analysis of memory dump files. It's not such a big issue because of the STOP 0x124 errors (it would be if there were other errors)
