I'm guessing it's the Auto installer for USB? don't want to get the wrong thing.

didn't run on boot up and only advice on the page is to " select USB to boot first" or something along those lines. Went into the BIOS advanced settings and hadn't a clue what to do and was afraid of changing the wrong setting , what do?;(

It's been a while but... the pc is still alive and I ran memtest today for 2 passes and got 0 errors. Still clueless as to what is causing these regular crashes.

ran another 2 passes today , 0 errors on mem test.

I read on a forum that the screen usually fills with errors on the first pass - I'll run it overnight tonight and see how many passes it's done :)
