yeah lets first see if we cant hit the BSOD problem first though, i really isnt to cool to start overclocking with a system that isnt really stable
I would now move on to hard drive diagnostics >>>> go to your hard drive manufacturers website and download their free diagnostic utilty >>>> make sure to run the extended drive test too
after the drive test is done
download othos >>>>

run orthos for one hour and watch your cpu temps with this program
http://www.alcpu.com/CoreTemp/
then report back what you highest temp is during orthos and better yet did it BSOD with othos running ???????????????????
