hello, sorry for my bad english but here it goes... e recently had a BSOD episode on my laptop when using internet sharing on my windows phone 8. Since then the CPU on my laptop sits at 100%. System process nt kernel 50%, explorer.exe 50% or sometimes System 50% svchost in all it's processes 50%. I have read the instructions on the first page off this thread, made my etl file, used windows performace analyzer and i narrowed it down to ntkrpamp.exe. But i don't have any clue what to do next, there are some functions i believe that are the culprits but i'm not shure. I almost forgot, there is another process that has a high count but it's marked with a question mark. I had the SPTD driver, but i uninstalled it and then made my tpl file http://www.sendspace.com/file/pcb2k0 Pls MagicAndre can you take a look at the tpl file? thank you
