That is decidedly "odd". I have no idea what could be causing the problem, or even how enacting non malicious code on a site could even have any effect. I would certainly think that it is something that is run on your PC in these circumstances that is doing the re booting.
When did it start?
Have you recently loaded any other programs.
Personally I'd do the Spike shuffle and run all of the clean up and a couple diagnostic programs.
My disk management is atrocious, so when anything untoward happens I hit it with a bloody big stick. I run Chkdsk, defrag, Update my antivirus and run it followed by Reg Cure, Spybot S&D, Adaware and if necessary PC Doctor (Deep scan) It's a decision born of panic, but for some odd reason, it's never failed me,.... YET!!
I have a saying and as far as I know it is a Spike original. My apologies if someone has beaten me to it.
