random bsod

Your .dmp files points to pctgntdi64.sys (PC Tools) as the cause of your crash... Completely uninstall this and Tuneup Utilities ... For the most part, these programs cause more problems than they are worth...

Try removing any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads

Good form old bean!

Yes, it can. Any hardware you suspect?

Upload the new dumps (if you get them, hope you don't!) and we'll take a look. Tew's advice was very good!
