Does a bugcheck 0x7F merit sending your PC for repair?

Well, that's what the Dell agent, via chat, told me: "I will be requesting for your system to be sent to depot for repair", 22 minutes after the chat started and after explaining to him to no avail all what I've done (testing, driver updates, etc.) after getting these blue screens. Apparently, not having straight answers to concrete questions prompt these agents to make this (ludicrous?) offer. After 35 minutes of not getting anywhere the "technical" chat came to an end. I made up my mind: I won't send my new laptop for "repair", not if I can help it. Mind you, I have used this system, as explained before, for running simultaneously several virtual machines, for watching movies, Internet TV, programming, etc. I believe there's is a driver (wish I knew which one) misbehaving and producing a kernel stack overflow specifically, in my computer, a stop error 0x7F: UNEXPECTED_KERNEL_MODE_TRAP with Parameter 1 set to EXCEPTION_DOUBLE_FAULT ((0x0000000000000008)... This incident reminds me when I took my first computer (some 20 years ago) back to the dealer because it was "not working properly", when in fact it was in perfect shape, not knowing, by that time, all the tricks and traps of the start up files (autoexec.bat and config.sys). You don't send a computer for repair, just because is not well configured. I've heard, in addition, that they may send you back a refurbished computer... Please note: after my previous post, when I declared no more blue screens, I got three of them in the same day, ten days later. Venue: a public library, as usual. Never in cafés, bookshops. Interesting...
