BSOD causing by ntoskrnl.exe

Using your windows disc you could try to repair your installation not re-install, there is a a chance that you might need new ram though. You should try this first www.youtube.com/watch?v=2c0onEJXU2E

Thanks, i tried SeaTools for Windows and MemTest but no problem was found, i also repaired windows, run sfc scan, still no problem.
I will let you know if BSOD happen again  

Oddly enough I've been seeing a rash of these BSODs lately related to ntoskrnl.exe. Most of them had other underlying causes such as hardware but there have been a few that were actually triggered by an advanced form of malware or rougeware.

I would recommend running either MalwareBytes Anti-Malware or Super Anti-Spyware or even both to see if it kicks anything out.

I already have Kaspersky Anti Virus 2013 and run a full scan but nothing were found

Ok, after a week with no problem, my laptop get BSOD again, and still causing by ntoskrnl.exe
